Vehicle Warranties

If you own a CA vehicle with a warranty, beware! Many dealers and manufacturers suggest that you need to get your car 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 manufacturer from voiding your warranty just because you got parts or services from a non-dealer. In fact, a manufacturer 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 manufacturer can prove that the replacement parts or service lead to a vehicle failure, they can void a portion of the warranty. Of course, Conv ... read more

PCV Valve Replacement

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

Exhaust Service

Whenever we talk about exhaust service, most people normally think about exhaust pipes and mufflers. Well, actually, exhaust service is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations. Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your vehicle manufacturer recommends you have your emission system checked out by a qualified San Diego exhaust technician regularly to make sure everything is working right - usually every 6 months or 10,000 miles/16,000 kilometers. If your Check Engine light comes on, especially if it's flashing, get your car looked at right away. Technicians at Convoy Auto Repair handle emission pro ... read more

San Diego Exhaust And Emissions Service

Sometimes when we talk about exhaust service, 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 Convoy Auto Repair is really a lot more comprehensive these days. For example, in the U.S., the federal government mandated catalytic converters for all cars in San Diego in 1976 and on-board emission control computers in 1990. CA 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 Convoy, regularly to make sure everything’s working right – which is usually every six mon ... read more

Coolant Service at Convoy Auto Repair

Our cars have to operate in a wide range of temperatures and our engine coolant must be able to perform 'no matter what'. Think for a moment about the environment where the coolant works.

Keeping Your San Diego Air Fresh When Driving With A Clean Cabin Air Filter

What is a cabin air filter? Is it: Clever you, it’s C. A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out common San Diego air particles like dust, pollen, spores, bacteria, pollutants, exhaust gas, odors and even sparrows. These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns. Not all vehicles in San Diego have cabin air filters. They are fairly new on the scene. About forty percent of new vehicles sold in San Diego 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 our San Diego 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 conditioning flow can become restricted. The filter can even get kind of smelly. Check your owner’s manual for recommended repl ... read more

Professional Fuel System Cleaning

Getting enough fuel to your engine is very important for performance, fuel economy and safety. In order to accomplish this, your fuel system needs to be clean. Today’s production cars have fuel injectors, rather than a carburetor. The injectors need to be cleaned from time to time in order to deliver the fuel with the correct pressure, spray pattern and volume. You can buy fuel system cleaners that you just pour into your gas tank that can help maintain an already clean fuel system, but can’t do a major cleaning. For that, you need to see Convoy Auto Repair. They have the tools and chemicals to do the job right. Convoy can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. You’ll enjoy more power, better gas mileage and reduced exhaust emissions. The cleaners also help prevent rust and corrosion in your fuel system and lubricate vital engine parts. And, as with all car maintenance ... read more

Tire Tread Depth for San Diego CA

So, when are your tires actually worn out? This is a question a lot of us in San Diego ask ourselves. For many, the answer is 'when they no longer pass a safety inspection'. But waiting that long can have a serious impact on your safety. The U.S. Federal government doesn’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at Convoy Auto Repair to find out what your requirements are in the San Diego area. Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give you enough safety? Well, Consumer Reports issued a call to consider replacing tires when tread reaches ... read more

Fuel Filter Replacement

You would never like to drink a glass of mud, right? Well, your car feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter's job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won't start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your car will still run. But, then the contaminated fuel can plug your fuel injectors and allow damaging particles into your engine. A car with a partially clogged fuel filter might run well around town, but sputter and strain on the highway because it's starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive and the gas you buy. If you drive a lot on dirt or gravel roads in rural CA, your fuel filter will have a harder time keeping the fuel clean. And, we hate to say it, but buyi ... read more
