San Diego Auto Repair

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? Can you see the smog? 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, to mix with the fuel and be burned. Without a filter, the inside of your engine would be extremely dirty from all the gunk that was burned in the cylinders. In fact, for every ... 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 car 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 San Diego automotive service center. That is why manufacturers recommend a belt ... read more

This is something really amazing: For every gallon of gas your car burns, it uses 12,000 gallons of air. All of that air has to be filtered to keep your engine clean. That’s like a hundred gallons of air every block! The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly car engine problems. Of course, your manufacturer recommends intervals for changing your air filter. But like most service intervals, where and how you drive your car affects when your filter needs to be changed. Dusty conditions in and around San Diego or polluted city driving means you’ll need to change your filter more often. Your Convoy technician can check your filter for you. In fact, it’s often a routine part of an oil change. When you think about it, a clogged air filter won’t allow as much air through as a clean filter. Your ... read more

With the recent focus in Mission Valley on improving fuel economy, we've been told how important it is to maintain our tire pressure. Everyone in Mission Valley 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 Mission Valley 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. Every vehicle in the Mission Valley 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 tun ... read more

Today we want to talk about timing belts. They’re something that many San Diego drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most San Diego car owners remember because it’s not well understood. Let’s review what a timing belt does. As you know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust ... read more

Today we’re going to be talking about serpentine belts for our 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 San Diego CA 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 San Diego CA, 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 desi ... 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 San Diego car owners making sure we follow the manufacturer's recommended maintenance schedules. Extend Vehicle Life with these Simple Tips Every time you go a couple thousand extra miles between a car oil change, you ... read more

Is your car sometimes hard to start? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your car's fuel system starts with the car air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy. Most of today's cars have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system. Some CA drivers are interested in buying fuel system cleaners that you can pour into your gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning ... read more

Hey San Diego, are your tires worn out? What is the standard for our CA streets? How can you tell on your sedan? While there may be legal requirements for the San Diego area, there are safety concerns that go beyond meeting minimum replacement mandates. 2/32 is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently. We're referring to the Consumer Reports call to consider replacing tires when tread reaches 4/32 of an inch, or 3.2 millimeters. And the recommendation is backed by some very compelling studies. The issue is braking on wet surfaces in and around San Diego. Most of us think of our brakes doing most of the work, but if you don't have e ... read more
