Hi San Diego residents. Let's talk fuel injectors. A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine. Because fuel injectors are such precision instruments, dirt and contaminants are a serious detrim ... read more

Sometimes we hear people in San Diego say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's vehicles are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most San Diego drivers don't realize how high tech automotive fluids have become,  fluids such as engine oil, transmission fluid, coolant and brake fluid.Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and distances march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories we've heard t ... read more

Today in the Pacific Highway Auto Repair auto care blog, we're going to talk to San Diego drivers about oil change intervals. It seems that as engine technology advances, oil change intervals become longer for Pacific Highway Auto Repair customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).In real world San Diego driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at Pacific Highway Auto Repair in San Diego.The vehicle manufacturers began to offer an extended warranty to cover sludge damage. B ... read more

All those automotive fluids can be confusing for San Diego drivers. Recent years have brought new grades of engine oil, types of transmission fluid, coolant and brake fluid. The right fluid protects your vehicle and helps it perform at its best. The wrong fluid won't work as well and could even cause damage.In addition to new grades of engine oil, many vehicles now leave the factory with synthetic oil. People in San Diego should always use the grade recommended by their manufacturer. All coolant, also called antifreeze, used to be green. Now there are several other colors of coolant sold at Pacific Highway Auto Repair in San Diego. Each type is designed to protect the cooling system components that are particular to your vehicle. The wrong stuff can void your vehicle cooling system warranty and could even cause engine damage.Most passenger vehicles on San Diego roads today use either DOT 3, DOT 4 or DOT 5 brake ... read more

A lot of San Diego, CA, folks are hoping to make their cars last a lot longer.Fortunately, with the current state of automotive engineering and manufacturing, there's no reason a modern vehicle can't be made to last for a 150,000 miles (250,000 kilometers) or more for smart San Diego drivers.The old adage: 'a stitch in time saves nine' is really true for San Diego residents when it comes to car maintenance.

When your experienced Pacific Highway Auto Repair technician changes your oil, he will also inspect your air filter. You shouldn't need a new air filter at every oil change, but you will need to change it regularly. Heed your technician's auto advice if they tell you to change your air filter.An air filter does what its name implies: it filters stuff out of the air. Air is drawn into your engine through the filter because your engine needs air to burn fuel. If the filter weren't there, a lot of dust and debris would come into the vehicle engine with the air when you are driving around San Diego. That dust and debris would get hot, burn and produce all kinds of ash and gumminess that would eventually clog up your engine. Drop in an air filter and voilá! Problem solved. But air filters themselves get clogged up with all the junk they clean out of the San Diego air. This doesn't allow the junk into the vehicle engine, bu ... read more

When San Diego drivers think about preventive maintenance, what usually comes to mind is oil, fluids and brakes. We don't generally think about our shocks or struts, but these auto parts keep our tires on the road.San Diego drivers don't think about shocks as often as oil changes because shocks and struts last a long time and wear out slowly. They don't need to be checked as often as our brake pads or air filters. By the time your shocks have 50,000 miles (80,000 kilometers) on them, their performance will have noticeable degraded. If you want to restore the handling and ride designed for your vehicle, try replacing your shocks and struts.Of course, if you drive off-road around San Diego, carry heavy loads, tow a trailer or put in a lot of mileage on poor driving surfaces, your shocks or struts will wear out more quickly. You'll need to replace them more often or upgrade to better shocks.Your suspension system uses springs and shocks to absorb the “shocks” a ... read more

The exhaust system on a vehicle is more complex than most San Diego residents realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All CA folks know a properly functioning exhaust system is good for the environment, but sometimes we forget that a damaged exhaust system can be deadly. That's why preventive maintenance on your exhaust system is so important. We can help you with that at Pacific Highway Auto Repair in San Diego.The exhaust manifold is the first component in your exhaust system. The manifold is attached to the engine. It collects the gases that are produced by the engine and directs them into the exhaust pipes. At this point, these gases are both hot and chemically dangerous.One of the gases produced in your engine is carbon monoxide. This gas is colorless and odorless. Breathing it can cause headaches, dizziness, nausea and drowsiness. Continue breathing it and you will die.To keep t ... read more

Is your vehicle sometimes hard to start early in the morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your vehicle's fuel system starts with the 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 San Diego vehicles 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 San Diego residents are interested in buying fuel system cleaners that they can pour into their 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. For that, you need to see Pac ... read more
