Power Steering Service in San Diego

Most San Diego drivers are too young to remember life before power steering - cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let's look at how it works. 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 for San Diego drivers to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why power steering 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 owner's manual for the right type - or just ask your friendly and knowledgeable ... read more

TCB your PCV (PCV Valve Replacement)

Your gasoline engine goes through some exhausting work.  Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve. Did you know it's a series of explosions that creates the power in your engine? The spark plugs ignite a mixture of gasoline and air and BANG! A whole bunch of those and you're engine is humming away. Leftover vapors from those explosions go into your crankcase, which is also a place where engine oil goes.  Those vapors still have a lot of unburned fuel in them, and if they had nowhere to go, they'd turn your oil into a thick mess called sludge, not good for a smooth running engine.  Engineers came up with an idea. Re-direct those gasses building up in the crankcase into the engine's air intake and mix them with fresh air.  That way the unburned fuel could go through the engine again and produce p ... read more

No Strain, No Gain (The Basics of Oil Filters)

Ever wonder what one of the best things is to ever happen to your vehicle's engine?  It's the little thing that usually looks like a can, the oil filter. Just like your kitchen sink strainer filters out errant particles of food from clogging your drain, the oil filter cleans out small particles that could cause your engine harm. Your engine operates in a dirty, hot environment and gathers a lot of tiny contaminants like dirt, dust, little metal shards and unlucky bugs that get sucked in.  Get those things circulating in your engine and those little particles can cause friction, which starts wearing out those finely machined metal parts.  You know how important it is to change your oil regularly.  It's vital that you change your oil filter at the same time to keep the oil as close to brand new as possible. Most oil filters look like a metal can with some holes in the bottom.  Inside there are carefully chosen materials that can screen out the contaminants while ... read more

It's Brake Time (Brake Calipers)

Race car drivers have demonstrated the advantages of disc brakes, so most modern vehicles use them.  Sometimes just the front wheels have disc brakes, but many vehicles now have them all the way around.  A major component of the disc brake is called a caliper.  It works by squeezing brake pads against the disc or rotor, kind of like a bicycle hand brake.  The brake pads themselves are what contact the rotor, causing friction to build and the wheel to slow down, but it's the calipers that apply the pressure to the pads. Caliper design has evolved over the years, and there are two common types.  One is called a floating caliper.  It has one or two pistons on one side of the disc. When you push down the brake pedal, the piston or pistons in your caliper put pressure on that one side.  A mechanism connected on the other side of the disc applies pressure as well, squeezing your disc so the vehicle stops.  Floating calipers are less expensive since the ... read more

How Much is Enough for San Diego Auto Owners? Tire Tread Depth

Most San Diego drivers know that tires wear out and that the wear has to do with tread depth. Most of us have heard that “bald” tires are dangerous, but most of us picture a tire with no tread at all when we think of a bald tire.

And how can you tell? Tires are and their condition is important to the safe handling of a vehicle, so it's for San Diego vehicle owners to know the answers to these questions.First of all, it's important to understand that there may be a legal limit to tread wear.

The Last Gas (Fuel Pump Replacement).

You're heading down the road and you notice your vehicle is sputtering, like it's running out of gas.  But the gauge show's it's still got a quarter of a tank.  So what gives? It could be that your fuel pump is failing, meaning your engine is not getting enough gas to run properly.  While fuel pumps are built to last a long time, sometimes they fail.  Other symptoms you may have a bad fuel pump include your vehicle stalling and then refusing to start again, the engine overheating or a hum or whirr coming from around the gas tank.  Or, your Check Engine light may come on. Most fuel pumps are in the gas tank. They have a small electric motor in them.   When you bring your vehicle to our service center, a technician will run tests to confirm the fuel pump is getting power to it but has failed.  Some vehicles have an access panel so the fuel pump can be removed and replaced.  But in some vehicles that don't have that access panel, the technician ... read more

Recommended Service Intervals at Pacific Highway Auto Repair

Most people in the San Diego area are aware that automotive manufacturers have recommended service intervals. Following recommended service intervals is very important. The engineers that design our vehicles have tested the various systems and components to meet durability and safety standards. Some of these standards are self-imposed and others, like those for emissions components, are government mandated for areas in CA.The maintenance schedules are designed to achieve the standards.

The Part You've Never Seen (Flat Tires and Solutions)

They say your vehicle has one, but you've never seen it.  And you might not even know it if you stumbled on it accidentally. We're talking about the jack, that tool that allows you to lift one corner of the vehicle up so someone can change a flat tire. So you say you'd never try to change a flat anyway, so you don't care where it is.  But one day, you may find yourself in a spot where you're stranded with no cell service and you'll need to at least know the basics of what to do. Well, here's the ironic part.  Many of today's vehicles don't even have jacks and spares!  Recently, manufacturers have been saving weight by supplying another solution for a flat tire, such as an inflator kit that has a tire sealant in it, or a small compressor.  If your vehicle has one of those, it's a good idea to get to know how to use it before you need to use it.  Hopefully you'll be able to call roadside assistance and they can take care of things, but circumstances may prev ... read more
