What is a cabin air filter? Is it: A filter for a house in the middle of the woods? A fresh, piney scent? A filter for the passenger compartment of your car? Clever you, it's 3. A cabin car air filter cleans the outside air before it comes into the passenger compartment. It filters out dust, pollen, spores, bacteria, pollutants, sparrows, exhaust gas and odors. These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns. Now not all vehicles have cabin filters. They are fairly new on the scene. About forty percent of new vehicles in CA come with cabin air filters, but the number is growing every year. Cabin air filters can make for a very nice driving environment. Your car can be a haven during allergy season with very little dust and pollen getting into the cabin. However, the filter eventually gets clogged. When this happens, your heating and air ... read more

The last new car sold with a carburetor in North America rolled out of the dealership in 1990. Since then, all new vehicles have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injection is a much more precise way of delivering fuel than carburetors. That translates into better fuel economy and power. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure. A few auto makers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection syst ... read more

We would like to give you an update on some of the things happening in automotive fluids. You know, cars are becoming more sophisticated everyday - and fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace. The do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many CA car owners rely on the advice of their service consultant to not only get the correct family of fluids, but to suggest the formulation that is best for their car and the way they drive. Proper Vehicle Fluids Let's start with engine oil. If you have been paying attention, you will have noticed a number of new oil weights on the scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in te ... read more

The government mandates a lot of equipment on cars: emission devices and control computers; safety equipment like airbags; and crash worthiness requirements. All of this is great for the motoring public, but it does add quite a bit to the price of a new car. Because new cars are more expensive, CA drivers are using their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge - but they need a little help to keep on going. Some owner's manuals don't specify higher mileage service requirements. That doesn't mean it doesn't have to be done. In fact, it's more important than ever to stay on top of routine car maintenance for vehicles with more than 120,000 miles/190,000 kilometers. Just extend regular serv ... read more

For most of us, it is hard to remember life without power steering - cranking those great big steering wheels? It was a pretty good workout. Now power steering is standard. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine - a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump. These hoses can develop leaks, so it is a good idea to inspect them at every car oil change. Low fluid can damage the power steering pump. That is why fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owners' manual for the right type - or just ask your service technician. The fluid cleans, cools and lubricates ... read more

Power steering is standard on nearly every car and truck in San Diego these days. Now there are some exotic, new types of power steering systems, but for the most part, the heart of the system is a pump that’s driven by a belt powered by the engine. The pump generates boost that assists you as you steer your sedan around San Diego, CA. Power steering systems use hoses to move pressurized fluid back and forth. These hoses can develop leaks so it’s a good idea to inspect them at every oil change. A check of the power steering fluid level is on the list for every full service car oil change because low fluid can damage the power steering pump. And the fluid needs to be compatible with the hoses and seals, so you need to use the correct type –just ask your service consultant at Convoy Auto Repair. In addition to providing boost, the fluid cleans, cools and lubricates the power steering system. The lubricants and ... read more

So you’ve bought a used car in the San Diego area. How do you know what you’re getting? It is hard to know what you’re getting because people in the San Diego area sell cars for different reasons. Think about why you’ve sold cars. Did you just want something new or were there problems that you wanted to run away from. Maybe it was a little of both. Used cars with 25,000 to 35,000 miles on them are often lease returns, corporate program cars or vehicles that have done duty in rental fleets. We feel pretty confident because they’re newer and may still be under warranty. But how well have they been maintained? If you plan on owning a car for a long time, you’ll keep up on the car maintenance so that you can avoid expensive repairs down the road. But, if you know you’re only going to have the car for two or three years, you may not be so committed to maintenance. It would be easy to think that skipping an oil change here and there wouldn’t ruin a brand new en ... read more

Richard Petty once said “You’ve gotta have good brakes. If you’ve got good brakes you can keep yourself out of a lotta trouble.” That’s why a regular brake inspection is on every San Diego car’s maintenance schedule. An inspection at Convoy Auto Repair will check your brake system and let you know if there are any problems. Of course, if you’re having trouble with your brakes, get your car into Convoy right away for brake service. Here are some symptoms to watch for: If you are experiencing any of these, it’s time to get your brakes checked. There are two types of brakes: disk and drum. Disk brakes have a rotor that’s attached to the axle. Calipers straddle the rotor, kind of like the brakes on a bicycle. Drum brakes are more common on back wheels. Both types have pads or shoes that press against the brakes and slow the vehicle. Brake pads and shoes are made out of very tough material to withstand the heat and force generated when stopping your car ... read more

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common, it is easy to prevent with radiator service. The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then goes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it's back to the engine again. There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is a mixture of water and antifreeze. The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage. Another very important coolant issue that is often overlooked is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted ... read more
