Every vehicle on CA roads has a differential, and it is important to the proper operation of the vehicle.  But most San Diego residents don't have a clue what it is.The differential compensates for differing wheel speeds. For example, when you turn, the inside tire on the turn travels a much shorter distance than the outside wheel. So the inside wheel of the vehicle must move at a slower speed than the outside wheel. Without a differential, the wheels would hop and scrape while turning.Have you ever seen the large bulge in the middle of the rear axle of a truck? That's the differential. In a rear-wheel drive vehicle, the differential is located on the back axle. Four-wheel drive vehicles and SUV's have differentials on both the front and the rear axle.You might expect that the differential is located on the front axle of a front-wheel drive vehicle. You'd be right. But the differential is called a transaxle on a front-wheel drive v ... read more

San Diego drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.Also, if it's freezing outside in San Diego, the water in your engine could freeze while your vehicle is sitting out in the CA cold.So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point than ei ... read more

Perhaps you've found yourself driving when something all of a sudden splashes on your windshield, obstructing your view. You know that sinking feeling when you try to turn on the windshield washers and no fluid comes out. Now you're blinded even more. What can you do? The best thing is to make sure your windshield washer fluid is always topped off and ready for these situations. You probably figure you'll grab a bottle of that blue stuff you see in the store. But is that really the right choice? One thing you know isn't the right choice is plain water. It can freeze when temperatures drop. Plus, when it's close to the freezing mark outside, spraying water on your windshield can freeze, turning it literally into frosted glass and blinding you suddenly. Water freezing in your vehicle's washer lines can also damage them. There are different types of windshield washer fluid made for different climates. Many have alcohol to prevent them from freezing; their label will usually tell you at wh ... read more

During an inspection at Pacific Highway Auto Repair in San Diego, your friendly and knowledgeable automotive service technician will check for worn, broken or missing parts. Here's a quick rundown of suspension system components: There are the springs which hold the weight of your vehicle. There are several varieties of springs. Springs are heavy duty parts that rarely break or wear out. Shock absorbers work in conjunction with springs to smooth out the ride and help keep the tires on the road. Good shocks are essential for handling performance and ride comfort. You've probably heard of struts. They combine a shock absorber and a coil spring in one unit. Shocks and struts will wear out over time. If your tires develop a cupped wear pattern, your shocks or struts may be wearing out. This is from the shocks bouncing unevenly. You may notice a floaty or drifting sensation when cornering. If the front of your vehicle dives excessively when ... read more

  Today we're talking to San Diego drivers about shocks and struts. They're so easy for CA folks to forget about because they last so long and wear out so slowly. But your shocks are really responsible for keeping your tires on the road – so they're very important.Without shocks, your wheels would be bouncing over bumps and lifting on corners. The shocks push the tire down to the road to maximize traction. Good shocks equal good ride quality and safe handling for San Diego drivers. There's a difference between shocks and springs. Springs support the weight of the vehicle, keeping it suspended up off the axles. The shocks moderate the rebound motion as wheels hit bumps. Now a strut combines a shock and a coil spring in one compact unit. It's best to replace all four shocks at the same time. That way you'll have even, predictable handling at all four corners. Anything less could be dangerous. Visit Pacific Highway Auto Repair to have y ... read more
