If you own a CA vehicle with a warranty, beware! Many dealers and manufactruers suggest that you need to get your maintenance services at a dealership in order to keep your warranty. That simply isn't true! You can have your vehicle serviced at your trusted, local service center without affecting your warranty. A federal law, called the Magnuson-Moss Warranty Act, prohibits a manufactruer from voiding your warranty just because you got parts or services from a non-dealer. In fact, a manufactruer can't require you to use their brand of oil filters, lubricant, or any other part in order to maintain your warranty protection. This protection is true for aftermarket extended warranties purchased on new or used vehicles. This protection also applies to leased vehicles. There are similar laws in Canada as well. If a manufactruer can prove that the replacement parts or service lead to a vehicle failure, they can void a portion of the warranty. Of cours ... read more

We live in such a disposable society. It's amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days people were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough - they had to do without. Most people couldn't afford new cars very often, so they had to make them last as long as they could. It's a good thing that cars are more reliable these days. They just don't break down as often. And the good news for us CA penny pinchers is that a modern car can easily go 200,000 miles/320,000 km with proper care. The engineering and the manufacturing quality is tremendous. The missing ingredient is us Van Nuys car owners making sure we follow the manufactruer's recommended maintenance schedules. Every time you go a couple thousand extra miles between an oil change, you have created an opportunity for sludge to be formed and clog passages. Then some p ... read more

The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Sludge is one of the biggest enemies of your engine, clogging it up, eventually leading to expensive failures. Also, the pressure build up would cause seals and gaskets to blow out. Therefore, these gases need to be vented out. Gasoline engines used to simply have a hose that let the poisonous fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. Diesel engines are not required to have these valves. The positive crankcase ventilation, or PCV, valve routes crankcase gases through a hose and back into the air intake sy ... read more

Don't you hate it when you hear that squeal from under the hood? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator-which charges the battery, the water pump-which cools the engine, the air conditioning and the power steering pump. All pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components. Serpentine belts are especially tough. They can last for years and go for tens of thousands of miles. But, with time they wear out. If your belt breaks while you are driving, everything will come to a halt within minutes. You have to stop the car or it will overheat, potentially causing major engine damage. And it probably won't be at a convenient time or place. You might even need to get your car towed to a Los Angeles automotive service center. That is why manufactruers recommend a belt replacement on ... read more

You may have found yourself in the following situation: You go to get your oil changed and the service adviser recommends you get a new engine air filter. You say yes, but because you didn't know what an air filter is or what it does, you were too embarrassed to ask. First of all, you did the right thing by getting a new one. And, you should never be too embarrassed to ask for more information. It's your money and you have a right to understand what you're paying for. Let's review what an air filter does. Air is the focus of this discussion. What is the air like outside right now? Is it full of pollen? How about dust? Anyone with hay fever can tell you that there's plenty in the air that you can't see. Well, it's the engine air filter's job to clean that air before it goes into your engine ... read more

All pilots have checklists for every aspect of flying. They always use their checklists even if they only have two steps on them. They do this simply because a checklist is a great way to not forget important steps. It is also how you can assure a predictable outcome. That is why Sherman Oaks and Encino automotive service centers have procedural standards for each service they perform. Technicians are trained step by step. And they perform the procedures step by step, the same way each time. By training to procedural standards, centers can assure a quality outcome. The job is done right every time and you are happy with how your car performs. Each company trains its technicians to standards. The industry as a whole is very committed to standards of excellence and encourages individual service center operators to apply them to every vehicle they service. An example is how service technicians grade problems and communicate their recommendations. If a technician tells you that a repair ... read more

The price of gas has got everyone talking. It seems that people who need a bigger vehicle to carry family and gear, or provide four wheel drive, are especially hit hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy. First let's start with how we drive. People may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster too. Another thing is to drive slower - but only when it's safe. Sometimes on the highway we drive an extra five ... ten . . . twenty ... over the speed limit. We do it to save time ... read more

A lot of our viewers have asked whether or not they should use their severe service maintenance schedule, which is listed in their car owners' manual. It can be confusing. Let's clear the air on this subject. Cricket Killingsworth is from QMI/Heartland, a manufactruer of automotive products and fluids. She's been in the automotive business for 20 years and is a speaker, a trainer, and a writer. Cricket says there's so much confusion on this topic because, "Most owners' manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service'. Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement, and transmission service be done more often: either in fewer miles or in less time. Manufactruers create these specific schedules for each vehicle they make. So there isn't on ... read more

If you're like most of us, you want your car to handle well. That's the job of your suspension system. There are different types of suspension systems, but they all work on the same basic principles. First, there are the springs, which bear the weight of the car. The most common springs are coil or leaf - although we see air springs and torsion bars more often. The springs do most of the work. But if all you had were springs, your vehicle would be bouncing around like a bobble head. That's where the shocks come in. They control the rebound of the springs and smooth out the up and down motions. They also keep the tires on the road, and you in control. Some cars use struts. Struts are a combination of shocks and springs, together in a more compact system. Shocks wear out slowly over time, so it's hard to notice when they get badly worn. One way to tell is to look for an uneven, cupping wear on your tires. If the shock or strut is leaking fluid, i ... read more

Ever heard the sad tale of a staggering repair bill from a broken timing belt? Bad news. Let's take a lesson from their woes and remember to think about our timing belt. First, let's review what a timing belt does. The top part of the engine, over the cylinders is called the cylinder head. The head contains the valves. There's at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves - that's 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It's called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything's in sync. The timing belt is a toothed rubber belt . But some cars use a timing chain ... read more
