Auto Repair in Camarillo

A driver of a large SUV loaded with equipment was heading on a 7-hour work trip when he stopped at a gas station to refuel.  When he went to restart his SUV, it turned over but wouldn't catch.  Try as he might, he was never able to get it started again. 

Of course there are many things that can cause those symptoms, but the next day he had his SUV towed to a service repair facility.  Using their test equipment, they were able to pinpoint the problem.  His fuel pump had failed.  The pump, which was located in the fuel tank, had to be replaced, and after awhile he was back on the road, delayed, but happy to be up and running again. 

What had happened is that the pump was not strong enough to deliver adequate  fuel to his engine, vital to being able to start it.  It had delivered just enough pressure in the morning to get it started the first time, but it was on its last legs.  He had been having trouble starting his SUV in the days leading up to this trip, a clue that something was wrong. 

The engine relies on a certain pressure of fuel from the pump to run properly, and there are some other signs to be aware of that your fuel pump may need to be replaced.  If you are putting strain on your engine, such as going uphill or hauling a big load, and the engine sputters, it may be a sign that the pump isn't delivering that consistent pressure.  Another warning sign is if your engine is running hot and then stalls.  That could mean your fuel pump is getting weak.

Sometimes you might notice your vehicle suddenly speeds up on its own or your fuel economy goes from good to poor in a short time.  If your fuel gauge shows you have plenty of fuel in the tank and your engine stalls, that's another possible sign of a failing fuel pump. 

Technicians have special equipment to see where the fuel problems are, and there are many possibilities.  Have your vehicle checked before you're left stranded.  Oh, and one more tip to prolong the life of your fuel pump.  Since it is cooled and lubricated by the fuel in your tank, make sure you keep at least a quarter of a tank of fuel at all times.  Avoid your "low fuel" light going on and you may be helping yourself avoid having to replace your fuel pump.

If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent.  But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should.

The oxygen sensors measure how much oxygen is in your exhaust.  If there's too much, it means there's a problem with the mixture of fuel and air.  The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency.  It does this constantly. 

Many vehicles have multiple oxygen sensors.  Some have one close to the engine, another close to the muffler.  Two measurements are better than one since they allow readings to be more accurate.  You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors.

Your oxygen sensors can fail.  One thing that can damage them is contamination from bad fuel.  The sensors can simply wear out, though they usually last a long time.  It's not unusual for an oxygen sensor to last 100,000 miles/160,000 km. One more thing that can cause an oxygen sensor to fail is residue from an engine that's burning oil.  Plus contaminants from the road like salt can also cause problems. 

Here are some signs that your oxygen sensors might be failing.

• The Check Engine light goes on.  In this case, your service facility can plug in a device that will read the code in your engine's computer to see if that's the problem.
• The engine is running roughly.
• Black, sooty smoke is coming out of your tailpipe.
• Your fuel economy is noticeably lower than it used to be.

Head to your service facility and tell your advisor what symptoms your vehicle is experiencing.  They have the equipment and training to track down the issue.  Note that simply replacing the oxygen sensor is often not enough since it doesn't get to the root of the problem; other repairs may be needed. 

So make sure your oxygen sensors are working the way they should be.  Oh, and back to the question of what gas makes up most of the Earth's air?  It's nitrogen, which comprises 78 percent of the air we—and our engines—breathe.

You notice when your smartphone's battery starts to go weak on you.  It runs out of juice faster than it did when it was new.  Bet you pay attention to that pretty closely.

Unfortunately, many of us don't pay the same attention to the battery in our vehicles. If your battery got you through the cold-weather months, you might be thinking you're all set until next winter. But you might be surprised to learn this: Hot weather is harder on a battery than cold weather.  (Note: we're talking about a conventional vehicle here, not an all-electric, plug-in one.)

 The way your vehicle's battery holds a charge is that it has chemicals inside it, and they react with each other to produce electricity.  A vehicle battery discharges electricity and then needs to be recharged.  Unlike your smartphone that you plug in each night to charge, the way a vehicle's battery gets recharged is by using the mechanical energy of the engine.  It's a pretty cool system that's been around for a while.  An alternator changes the mechanical energy into electricity that then charges the battery.  And your vehicle is designed to charge it just the right amount with a voltage regulator. If your battery constantly gets too much voltage, it could stop holding a charge. 

Another way a vehicle battery loses its ability to hold a charge is when it gets hot.  In warmer weather, some fluids in your battery evaporate which can damage some of its internal components.  Then, you've got a dead battery.

Back to your smartphone for a second, it probably has a little indicator or maybe an app that shows you how healthy it is or how much charge it's holding.  Well, your service repair facility has equipment that can test your vehicle's battery for the same things.  If that test shows you need a new battery, then it's probably time to replace it.

A technician can also check to see your battery is being charged at the correct rate.  If you have a battery that is not sealed, a technician can check to see it needs more water added to it.  The technician will also make sure dirt or other contaminants aren't acting as electrical conductors and discharging the battery.  Plus, your battery's terminals may need cleaning.

Most people just forget about their vehicle's battery until there's a big problem with it. Here's one rule of thumb: expect a battery's life to be about 5 years. Just like you wouldn't want your smartphone to leave you without any way to make phone calls or send texts, you wouldn't want your vehicle to leave you stranded with no way to start it, would you?   

When it comes time to make that new battery choice, your service advisor can offer you some good options, taking into account the climate you drive in, what you use your vehicle for and what your budget is.  Hey, your smartphone's battery is all charged up.  How about calling your service advisor for an appointment right now?

If you hear a squealing noise when you turn your vehicle, it's trying to tell you something is wrong.  After all, it never made that noise before, right?  The sound  you hear may becoming from a few sources.  Let's take a look (or a listen) to some of the possibilities.

First, you almost certainly have power steering in your vehicle. Without power steering, you practically have to have arms like Arnold Schwarzenegger to turn, so automakers have technology to assist your steering, either mechanically or electrically.  For a long time, the most common power steering has been hydraulic, using a belt to supply power from the engine that turns a power steering pump full of a fluid that helps you steer. 

Sometimes that fluid gets low because of a leak or some other problem.  The belt could wear out and start squeaking, and you might feel the steering start to become harder.  Your service repair facility can figure out the problem and offer some solutions.

Another cause could be in your suspension.  Some components may not be getting lubricated like they should.  Or you may be hearing your tires squealing when you are turning. 

Properly working steering is a huge safety factor for your vehicle's operation.  Your steering affects handling, vital to your well-being as well as that of drivers around you.  So take your vehicle over to your repair facility and have it checked out.  You'll be doing everyone on the road—including yourself—a big favor by listening to your vehicle. When it comes to steering, silence really is golden.  Get that squealing repaired and get back to safe driving.
