Whenever they hear the term "exhaust service," most San Diego residents think about exhaust pipes and mufflers. Well, actually, exhaust service at Pacific Highway Auto Repair 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 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.

It's one of those things that can happen on a multi-day road adventure or a quick trip to the grocery store.  You hit a pothole, go too fast over a speed bump, nail a curb.  When it happens, you think, "I wonder if that was hard enough to do any damage?"  But things seem ok and you continue on your way.  Keep in mind that any blow to your vehicle's suspension can throw it out of alignment.  It can be a hard knock from the road or from another vehicle, such as being involved in a minor accident.  When your suspension is out of alignment, it means that the wheels aren't all pointing where they should.  And after a while, it can make your tires wear unevenly and cause problems with steering and handling. Let's go back to that pothole or curb you hit hard.  Even though you think there was no damage done, if you wait until you see tire wear, you may need to replace all four tires, not an inexpensive proposition. That's why it's a good idea to make sur ... read more

  Today we're going to be talking about serpentine belts for our San Diego, CA, 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 CA in the summer.The power steering and power brake pumps are driven by the serpentine belt in most San Diego residents' vehicles. Those pumps provide 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 ... read more

San Diego auto owners may know that most automotive failures in San Diego, CA, are tire related, but do you know the second most common cause of vehicle failure? Nope, it's not teenagers. It is the coolant system. But if you take good care of your vehicle coolant system, it will take good care of you.A vehicle's engine creates a lot of heat - so much heat, that if it is not properly cooled, the engine can lock up, resulting in massive damage and repair bills. But when everything is working right, your vehicle engine operates at the proper temperature and all is well. Without antifreeze in your cooling system, the water could freeze and cause vehicle engine damage. This could be very expensive, not to mention inconvenient.The right mix of water and antifreeze protects the engine against damage from freezing and overheating. Antifreeze also protects the coolant system against corrosion that could cause the system to fail. The thing to remember is this: coolant system failure is ver ... read more

The timing belt rotates the cam shafts which open and close the valves that allow air, fuel, and exhaust to flow through the engine as it powers your car when you drive around San Diego.An old timing belt can lose a “tooth” in the belt allowing it to slip. The engine could stop or misfire. Timing belt slips – or a broken timing belt – can be disastrous on some engines. In “interference” engines, open valves can get in the way of the piston when the timing belt breaks or slips. When that happens one or more valves can be bent requiring expensive engine repairs.It is important for San Diego drivers to replace their timing belts as recommended in their owner’s manual to avoid unnecessary breakdowns. Ask the team of professionals at Pacific Highway Auto Repair in San Diego if it’s time for your timing belt to be replaced.

Mirror, mirror on the door, why is my vision there so poor? Well, you could have a broken outside rearview mirror that's disabled your blind spot vision there and endangering your ability to see some of the traffic around you.  Outside rearview (or door) mirrors are important safety devices that are thoughtfully designed to help drivers see.  And there are a variety of ways those door mirrors can develop problems. One is when the glass is broken in them.  Sometimes it's caused by an accident or vandalism.  But without your ability to see in that mirror, you could be driving blind, unable to see drivers approaching from the rear in adjacent lanes.  Sometimes it's as simple as having the glass replaced.  You'll greatly enhance your safety if you do. Then there's the door mirror that you can't adjust.  First, let's look at a common scenario in later models, the power mirror.  They're great when they're working, awful when they're not.  Sometime ... read more

So you thought you only had two brake lights.  Look again and you'll see one in the center at a higher level than the two on either side of the vehicle.  They're sometimes in the inside of the vehicle behind the back window, or they could be in the deck lid, on the roof or on the spare wheel carrier, But why is that third brake on your vehicle? Experts say it helps prevent rear end collisions. Tests done by installing the third brake light in taxis and fleet vehicles showed fewer rear end crashes in the ones that had the extra light. The third brake light was mandated in new passenger cars in 1986 in the US and Canada.  The requirement was added to new light trucks and vans in 1994. Sometimes it's difficult to know if your third brake light is even working.  Many vehicles have bulb warning systems that alert you to non-functional bulbs, but not all do. Your vehicle service facility will often check to see if all your turn signals, taillights and headlights are worki ... read more

Sometimes busy San Diego residents dream about going back to the “simpler” days of our grandparents. But if you could travel back in time and take a road trip around CA in a Model T, you might change your mind. The improved designs and quality of today's automobiles have significantly reduced the amount of time San Diego residents spend at the side of the road during breakdowns. With proper maintenance, today's vehicles can stay on the road longer than ever before.Some of those improvements, however, have led to higher repair costs. For example, older cars often broke down from vapor lock. Gas vaporized while traveling from the gas tank to the fuel pump. No gas, no power. The car quits going. The solution was simple — you just sat by the road until the car would start up again. Today's San Diego drivers would hardly tolerate that kind of inconvenience, and it's likely that yesterday's San Diego drivers didn't care much for it, either. So on today's vehicles, the ... read more

You've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information.  There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on.  Let's check out this example found on an SUV: P245/70R17 108T. The first letter, P, means it's intended for passenger vehicles.  If there's no letter, it means it's a metric tire.  If there's an LT at the beginning or end that means a tire designed for light trucks. Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall.  The number that follows in our example, 70, means the height of the tire is 70% of its width.  The letter after that in our example, R, describes the type of tire (on this vehicle, radial).  Following that is the diameter in inches, in our SUV example, 17 inches.  How much load the tires' sidewalls are designed to take ... read more

There are some boots that don't come in a shoe box and aren't worn on your feet.  They are called axle or CV boots, and they can be important parts for many vehicles. That CV stands for constant velocity.  CV axles are mainly used in front-wheel drive and all-wheel drive vehicles. They're also used in some rear-wheel drive vehicles with independent suspensions.  They have two CV joints, one inner and one outer, placed between the axle and the drive wheels.  That way the vehicle's engine power can drive the wheels, no matter what angle they are.  They also adjust for the different speeds wheels turn as they go around corners.  Because roads are full of all sorts of hazards (dirt, oil, water, grime), these CV joints need to be protected.  They also have grease in them to keep the bearings moving smoothly.  That's the job of the rubber boots that are supposed to keep that debris out.  These CV or axle boots are made of rubber or plastic and usu ... read more
