Don’t be embarrassed if you don’t know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Costa Mesa California, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. You might even have two or three.

As you might guess from the name, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner near your Costa Mesa California home. Your inside wheel has a shorter distance to travel than the outside wheel as you go around the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power. Without a differential, our tires would scrub and hop along the pavement during turns.

You’ve probably noticed the big bugle in the middle of the rear axle when you’re behind a truck. That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. Front-wheel drive vehicles’ differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complicated. But you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but they need to be properly lubricated in order to stay strong. So from time to time, you need to have your differential serviced. The used fluid is drained and replaced with clean fluid. Some differentials also require special additives to be installed.

The rule of thumb for the time and mileage interval for servicing your differential, can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your Costa Mesa California service advisor or your owner’s manual for recommendations.

How and where you drive will have an impact as well. If you drive on dirt roads or through streams around Costa Mesa California, you’ll need to service the differential much sooner than if you always stay on the pavement.

Tires do a lot of work. They transfer engine power and braking forces to the road; they handle steering control; and they cushion all those bumps and jolts. They also support the entire weight of the vehicle, including you and your passengers. With such critical work to do, you want your tires to do their job well. And since replacing tires is fairly expensive, you want them to last as long as possible.

There are three keys to long, even tire wear:

• Proper tire inflation
• Proper wheel alignment
• Regular tire rotation and balancing

The front tires on a car take the brunt of the steering forces. As they push through turns, the shoulders of the front tires wear down more quickly than the rear tires. Rotating front and rear tires allows them to all wear at about the same rate. That’s especially true of front wheel drive vehicles whose front tires steer, and put the power to the road.

SUVs and pick-ups, especially four wheel drives, also tend to wear their tires more unevenly than cars because of their suspension and drive train set-up. Your owner’s manual will likely contain a schedule for tire rotation. It’s usually every 5,000 miles or so.

Also, there are different rotation patterns for different vehicles. Bimmer & Benz Specialists will know which is right for your vehicle. That brings us to wheel balancing. When wheels are balanced, they spin on the axle evenly. When they are out of balance, they wobble a bit. That makes the tires wear unevenly and may transmit a vibration to the car. Your service technician at Bimmer & Benz Specialists puts weights on your wheels to balance them out so that they turn true and smooth.

Tires are a big investment for any vehicle. They’re critical for keeping you safely on the road. The cost for regular rotation and balancing is more than made up in extended tire life. And, can you really put a price on your safety and that of your passengers?

Today we’re going to be talking about serpentine belts for our Costa Mesa California customers. Let’s start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That’s the device that makes electricity to power the vehicle and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you’re driving around Costa Mesa California in the summer.

The power steering and power brake pumps are driven by the serpentine belt in most vehicles. Those pumps make the pressure that assists your steering and braking.

In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around Costa Mesa California, the water pump is driven by the timing belt.

The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That’s really a lot of work for one belt.

But modern engine design has a single belt that snakes around the front of the engine and drives most if not all of these accessories. Serpentine belts do a lot of work, but they’re tough and can last for thousands of miles.

Just how long will they last? That’ll vary for each individual car in the Costa Mesa California area. Your manufacturer will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection can reveal a belt that’s getting close to failing.

Bimmer & Benz Specialists can look at the belt: if it has more than three or four cracks per inch it needs to be replaced. A deep crack that’s more than half the depth of the belt – replace. Frayed, missing pieces, a shiny glazed look? It’s out of there.

What’s involved in replacing the belt? First the old belt is removed. Then a new one is fitted around all the pulleys for the accessories and the drive. There’s a special pulley called a tensioner.

This pulley is mounted to the engine block with a spring loaded arm. Its job is to apply the correct amount of tension to the belt to keep it from getting loose and maybe slipping off. Because the spring in the tensioner pulley wears out, AutoNetTV recommends replacing them at the same time as the belt. It just makes sense.

What are the warning signs that there’s a problem with the serpentine belt? You may hear a squealing sound from under the hood when accelerating around our Costa Mesa California streets. A loose belt might give you a slow, slapping sound.

What do you do if your belt breaks? If you’ve actually had that happen on our local Costa Mesa California freeway, it can be a little scary. Often the first thing you notice is that you have no power steering or power brakes. Don’t panic – you can still steer and brake, but you’ll have to do the work. It’ll be harder to steer and you’ll need more time and effort to stop, so plan accordingly.

Your dashboard will light up will all kinds of warnings. You’ll see a warning about your cooling system if you have a water pump that’s driven by the serpentine belt. This is very critical because without your cooling system working, your engine will overheat. If you don’t stop you’ll have massive engine damage, maybe to the point that you need a new engine. Pull over as quickly as you safely can. Open your windows and turn the heater on full blast to provide a little engine cooling and pulled over as soon as possible.

The battery light will come on because the alternator isn’t working. If your car’s water pump isn’t driven by the serpentine belt, you’re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car won’t run and will just shut off. You don’t want that to happen while you’re driving in our local Costa Mesa California traffic.

Remember, this does not have to happen if you replace your serpentine belt on schedule. Ask your technician at Bimmer & Benz Specialists to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.

With the recent focus in Huntington Beach on improving fuel economy, we’ve been told how important it is to maintain our tire pressure.

Everyone in Huntington Beach knows that tires wear out, but we all want to make them last as long as possible because they’re fairly expensive to replace. In addition to saving gas, properly inflated tires last longer. Under-inflated tires will wear out more quickly.

Some people in Huntington Beach wonder if there is benefit to adding a few extra pounds of pressure when they fill up their tires. But actually, there isn’t. In fact, there are very good reasons not to over-inflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling.

Come in and see us about tire maintenance for your Costa Mesa, California vehicle.

Every vehicle in the Huntington Beach area has a sticker on the driver’s side door jamb that tells you the manufacturer’s recommended tire pressure. This recommendation is an integral part of the vehicle’s suspension tuning. A lot of engineering actually goes into the recommended tire pressure, so it’s important to follow it.

What else do we need to know about tire maintenance? Tire rotation and balancing are very important. Let’s start with rotation. Because the front tires handle the brunt of turning forces, the shoulders of the front tires wear more quickly than the rear tires. We rotate the tires so that they all get to do some duty on the front and they’ll all wear evenly over their life.

For most vehicles, front tires are rotated to the rear and vice versa. Others recommend a cross rotational pattern. Some vehicles use an asymmetrical tire so those tires need to stay on either the right or left side – it’ll say which on the tire. Some high performance cars have asymmetrical tires and different sizes on the front and rear. These can’t be rotated at all. Your owner’s manual will have details for your car.

How often should you rotate your tires? Your owner’s manual will have a recommendation. Your service advisor at Bimmer & Benz Specialists can do a visual inspection to let you know if it looks like it should be done. The interval is typically around 5,000 miles.

You know, some people don’t think new tires need to be balanced. What they aren’t taking into account is the wheel. Between the wheel and the tire – even a new tire – there’s enough variation to require balancing.

When you add the valve stem and tire pressure monitoring sensors required on new cars, balancing is definitely in order. When a tire’s out of balance, it’s actually hopping down the road. You’ll feel the vibration through the steering wheel if a front tire’s out of balance and through your seat if it’s a rear tire.

Proper wheel balance promotes tire life and increases safety. Historically, lead weights have been attached to the wheel to bring it into balance. Lead gives some environmental concern, so steel weights are starting to be substituted.

Also, always use the same size tire on an axle. Different size tires on the front or on the back can lead to some real handling problems. And tire manufacturers recommend that when you get two new tires, they be installed on the rear because that’s where you need the most traction to avoid spinning-out.

Sometimes when we talk about exhaust service in Costa Mesa, we think about exhaust pipes and mufflers. And if you can see smoke, or if it’s too loud. But, exhaust service at a place like Bimmer & Benz Specialists is really a lot more comprehensive these days.

For example, in the U.S., the federal government mandated catalytic converters for all cars in Costa Mesa in 1976 and on-board emission control computers in 1990. California and federal emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations. Cars sold in Canada follow the same guidelines.

So, exhaust service has really become exhaust and emissions service. High-tech computer-controlled emissions devices are now a big part of that. And because it’s so sophisticated, your vehicle manufacturer recommends having your emission system checked out by a qualified technician, like the ones we have at Bimmer & Benz Specialists, regularly to make sure everything’s working right – which is usually every six months or 6,000 miles.

If your ‘check engine light’ comes on while you are driving around the Newport Beach area, especially if it’s flashing, then you need to get your car looked at right away. Chances are it’s an emission related problem. You might have exhaust or emissions trouble if your car is hard to start, runs rough, or if it’s noisy or smoking.

So let’s review the exhaust system. Everything starts with the exhaust manifold. That’s the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe.

The exhaust gaskets help seal the connection with the manifold and other joints along the way. Now, if the manifold is cracked or loose, or a gasket is leaking, then dangerous gases could escape into the passenger compartment, where you ride. Carbon monoxide can be deadly, so it’s important that your exhaust system doesn’t leak.

The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next comes the catalytic converter. This part actually looks like a muffler. It changes chemicals that are dangerous to your health, and to the local California environment, into harmless carbon dioxide and water. Now it doesn’t require any maintenance itself. But eventually they wear out. If it has, you’ll probably find out when your car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car’s sound with different mufflers – which is pretty cool because you can change the look of your car, and the way it sounds.

Rusted or road-damaged mufflers can actually leak and they need to be replaced right away. The exhaust system is attached to the car by a series of hangers and clamps that hold the system in place. And when these hangers come loose or break then hot exhaust components can touch and melt wires, hoses and lines. Just think of the damage a hot curling iron can do – but worse. It’s not good to have that waving around.

And finally, we end at the tailpipe. Appropriate name. This is the final outlet for the exhaust. And one other component is the oxygen sensor. It monitors the oxygen content of the exhaust so the engine-control computer can adjust the fuel-to-air mix to keep the car running right.

We hope this hasn’t been too ‘exhausting’ of a discussion, but these things impact everything from life and death safety due to exhaust leaks, to just fine-tuning the sound of your ride. And talk with your service advisor at Bimmer & Benz Specialists if you feel you need any of these items inspected on your vehicle, because a quick look can sure save a lot of pain down the road.

Auto Tips Videos provided for Bimmer & Benz Specialists by AutoNetTV

So you have some exciting plans for the California weekend. You’re going to take some of your Costa Mesa, California friends out on the boat for some water skiing. Of course, you’ve gotten the boat all ready. And you haven’t forgotten about your tow vehicle. You’ve gassed it up and even vacuumed it out. But you want to make sure that your sedan maintenance is up to date.

Think about it – heavy traffic on the way out of Costa Mesa. There’s hilly terrain as you get to the lake. Some dirt roads – and its going to be pretty hot in Costa Mesa this weekend. And all the time you’ll be towing around several thousand extra pounds. That all adds up a lot of severe strain on your engine, brakes and transmission.

Let’s just consider the transmission. It’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What’s a fun little blast to the local California lake for you is really severe duty for your transmission.

It’s important to have enough transmission fluid. If it runs low, the transmission will run hotter and won’t have the protection it needs to cope with the added stress of towing. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced at Bimmer & Benz Specialists on schedule to make sure it runs efficiently.

An automatic transmission contains a maze of passages through which the fluid has to pass to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems.

Neglect your transmission for too long, and it can fail. You really don’t want to pay for a major transmission repair.

This reminds us of how much of our driving around Costa Mesa, California is under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips, driving in very hot or very cold weather. Dusty roads and city driving around Costa Mesa, California add to the strain. Basically, any driving that’s not at highway speeds or under ideal conditions.

While you have your vehicle in, ask for a trip inspection. Your Costa Mesa, California service technician at Bimmer & Benz Specialists will check your belts and hoses and let you know if your brakes are in good shape.

Now, don’t forget the sunscreen.

No matter how well they’re made, vehicles in Costa Mesa, California will have design or manufacturing problems.

And when the government thinks a problem is really serious for people in Costa Mesa, California, they require the manufacturer to issue a recall notice and fix the car free of charge. The manufacturer then tries to contact everyone in Costa Mesa, California who owns that type of car to get the recall work done. Perhaps you have received a postcard notifying you of a recall issue on your car.

Because these recalls always affect safety, Newport Beach drivers should take them seriously. This isn’t difficult to do because it’s easy to see if a vehicle’s being recalled.

The government has links on its websites, or just visit AutoNetTV for links.

There are many websites with free recall information and searches. There’s CarFax, AutoByTel and the DMV.

Recalls are serious, but not all that common. But sometimes there are less significant issues, and for these, auto manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like Bimmer & Benz Specialists how to repair a frequent or difficult problem.

The pros get updated information through subscription plans, also available in consumer versions for a reasonable cost.

So when auto manufacturers recalls occur, get the work done, and keep you and yours safe.

Our cars have to operate in a wide range of Costa Mesa, California temperatures and our engine coolant must be able to perform ‘no matter what’. Think for a moment about the environment where the coolant works. Very hot, high pressure, corrosive…

And all the while, it has to protect the components of the cooling system from corrosion. These components are made from steel and aluminum, plastics and rubber. The coolant has to be formulated to protect against corrosion for all of these different materials. That’s why different manufacturers recommend different types of anti-freeze for our Costa Mesa, California vehicles.

There are several different ‘families’ of anti-freeze available to us here in Costa Mesa, California. Your owners’ manual will tell you what kind you should use. Of course, Bimmer & Benz Specialists will know what to put in your car.

It’s important to stay on top of this because coolant system failure is the most common mechanical problem people have here in Costa Mesa, California. Regular service at Bimmer & Benz Specialists needs to be done to avoid failures and also to keep your warranty in place.

While the specifics of the service required may vary from vehicle to vehicle, your service consultant at Bimmer & Benz Specialists will know what to do. You’ll be advised to replace the coolant at specified intervals.

Some manufacturers may recommend periodic coolant system flushes. A flush adds a cleaning step to the fluid replacement process. Again, check to see what your service consultant recommends.

Someday, you may have to deal with an overheating problem, so you need to know what to do if your coolant temperature warning light comes on or your temperature gauge is in the hot zone.

Now, overheating can be very expensive. You can literally melt down your engine and have to replace the whole thing. So take the warning signs seriously and take immediate steps.

First turn off the air conditioner. This will lower engine temperature right away. Next turn your heater to maximum heat and run the fan at high speed. You might need to roll down the windows, but this will take a lot of heat off the engine.

Pull over as soon as you can safely do so, especially if you are stuck in slow-moving traffic, and shut the car off. It may take as much as 45 minutes for the engine to cool to the point that it’s safe to operate the car again.

If you need to add water or antifreeze, be sure to wait until the car cools down. Opening the radiator cap or even the overflow bottle when the coolant is hot and under pressure may result in serious burns.

So after the engine has cooled for 45 minutes or so, look to see if the coolant is low in the overflow tank. If so, you can cover the overflow tank cap with a large cloth and open the lid. Then start the engine and pour in some water or antifreeze. Pouring it in when the car is running will circulate the new, cool fluid with the warmer fluid in the engine and avoid engine damage.

Of course, overheating is a serious problem and you need to get it fixed right away. Bimmer & Benz Specialists can make sure the coolant is right before you drive home.

Those spring and winter inspections really come in handy when they head off a cooling system problem. And don’t forget that severe service driving conditions, like towing or hot, dusty driving around Costa Mesa, California, mean that you’ll need to service your coolant more frequently.

At AutoNetTV, we suggest that you have Bimmer & Benz Specialists inspect your coolant system to find small problems before they become big, and to change belts and hoses before they fail. After all, we don’t want you to lose your cool out there in Costa Mesa, California.

If you’ve ever been in a car accident around Costa Mesa California, even a minor one, you know how upsetting it can be. It’s hard to think straight and know what to do.

Let’s review what you should do in case of an accident in Costa Mesa, California:

When an accident occurs, you should always stop. Leaving the scene of an accident is considered a crime in California – even if it’s not your fault. And hit-and-run penalties are fairly severe, possibly resulting in steep fines, loss of your driver’s license or even jail time in our local Costa Mesa lockup.

Most states, including California require that you try to help someone who is injured by calling for help or performing first aid if you are able.

Warn other Costa Mesa motorists by putting out flares, using your flashers or lifting your hood.

Call 911 as soon as possible. Tell the operator if medical or fire help is needed.

Always file a police report. It’s tempting to skip this if everything seems to be ok. But without a police report, the other guy can say whatever he wants about the accident later, and you won’t have an objective report to help defend yourself.

Discuss the accident only with the police. Emotions are strong after an accident and we naturally want to talk about it – don’t. Never admit fault or guilt to anyone including the police officer. Sometimes we may feel at fault, but in the eyes of California law, the other guy may be responsible.

Truthfully give the officer the facts: such as “I was going 35 miles per hour” not “I wasn’t speeding”. Remember, anything you say to the officer or anyone else can be used against you.

Also get the officer’s name and badge number and ask where you can get a copy of the accident report.

Get the facts on the driver and owner of the other vehicle:

• Name
• Address
• Phone number
• Date of birth
• Driver’s license number and expiration
• Insurance information

Also take down a description of the other vehicle, license plate and vehicle identification number. Most insurance companies don’t record license plate numbers, so the VIN number is the best way to track the vehicle.

Ask witnesses, including passengers, to wait for the police. If they can’t wait, ask for contact information and request that they write a brief description of what they saw. If someone refuses to leave their name, write down their license plate number so the police can track them down later if necessary.

Always call your insurance agent or your California auto insurance company’s 800 number.

Call or see your local Costa Mesa physician if you think you may have been injured.

We here at Bimmer & Benz Specialists hope that you never have to use this information and wish you happy travels.

If you’ve ever heard a squealing sound under your sedan hood, chances are it was your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems in your sedan. Let’s go over them.

First, the serpentine belt drives your air conditioning system. It spins the compressor that makes the cool air that takes the edge off the summer heat in Costa Mesa.

More importantly, the belt powers the alternator. The alternator creates electricity that’s used by your sedan’s electrical systems and also charges your car battery. Without the alternator, the battery will go dead in a few miles.

The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost).

And, on most sedans, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within optimal operating temperatures. On some Costa Mesa cars, the water pump is powered by the timing belt instead of the serpentine belt.

When they understand what it does, Costa Mesa auto owners realize that if it breaks, it affects a lot of systems. That’s why vehicle manufacturers outline recommended replacement guidelines in the owners manuals. If this important maintenance component is not included in your owners manual, come see us at Bimmer & Benz Specialists.

At Bimmer & Benz Specialists in Costa Mesa, your service advisor can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon. If the belt has more than three or four cracks every inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.

If it has lost a significant amount of thickness, it also needs to be replaced. There’s a special spring-loaded pulley attached to the engine called the tensioner pulley. Its job is to make sure there’s a constant tension on the serpentine belt so that it doesn’t slip. The spring can become worn and no longer provide the necessary pressure to keep the belt tight. At Bimmer & Benz Specialists, we recommend that the tensioner be replaced at the same time as the serpentine belt.

As mentioned, a squealing sound could alert you that the serpentine belt needs to be replaced. It may be loose if you hear a slow, slapping sound when idling your sedan.

All in all, the serpentine belt’s is critical to the operation of your sedan. And it’s not that expensive to replace at Bimmer & Benz Specialists – so it’s good to do so before it fails.
