Not So Hot in Brea

When the weather turns cold, it's nice to crank up the furnace and enjoy the heat. But if your home's furnace doesn't work, it's not too comfortable. Same goes with your vehicle. When the heater's not working, things can get miserable. It could also signal some major problems, which we'll discuss later.

A vehicle's heating system is fairly complicated. It's made up of several parts, including a blower motor/fan, a heater core and some mechanical and electrical components. In basic terms, a vehicle's engine warms up coolant which is then sent to the heater core (which is kind of like a small radiator) behind the dash. That blower motor sends cold air through the heater core which heats up the air. Voila! Heat.

Diagnosing problems in this system takes a trained mechanic because of the different possible issues. Your heater core may need replacing; they are sometimes in tight spots and may be difficult to work on. Another possible problem could be a defective thermostat, which regulates how the coolant flows through the engine. You may have a leak somewhere in your cooling system. Those leaks may be something as simple as a detached hose clamp or as serious as a bad head gasket. A knowledgeable technician at Star Auto Service & AC will be able to track the problems down.

For those reasons, it's wise to get your vehicle's heating system repaired. Not only can driving an unheated vehicle on a cold day freeze your fingers, some related engine problems that are not repaired could leave you stranded.

Smart drivers keep up the maintenance on their vehicle's cooling system; it's a hot tip to prevent a cold vehicle.

Change is Good (Oil Change)

You've heard that expression, change is good.  When it comes to your vehicle's oil, change is not only good, it's vital for the health of the engine.  But there's one question that puzzles many drivers: how frequently should my vehicle's oil be changed? There is not one simple answer, but here are some guidelines that will help.

It used to be pretty much a rule of thumb that vehicles got their oil changed once every 3 months or 3,000 miles/5,000 kilometers.  But times have changed.  Oil formulations have gotten better and engine designs have made longer oil change intervals possible. 

Most experts advise you to read the recommendations that come from the manufacturer that designed and built your vehicle.  Their designers and engineers know more about your vehicle than anyone else.  They spell out their recommended oil change interval and type of oil in your owner's manual.  Many automakers say you can go at least 5,000 miles/8,000 kilometers between oil changes and many recommend even longer intervals now.  If you use synthetic oil, it doesn't have to be changed as often. 

Ever wonder why you have to change your oil?  Your vehicle lives in a dirty environment.  Contaminants build up in your engine oil and, after time, they inhibit the lubricating properties of the oil.  Without optimal lubrication, increased friction inside the engine starts wearing down the metal parts, shortening the engine's life.

Not only do vehicle manufacturers recommend oil change intervals in the manual, many also now alert drivers by a light or other electronic indicator on your dash.  It doesn't exactly say, "Hey, time get your oil changed. This oil's starting to wear on me." But it does give you a pretty good hint.  Some of these warning systems simply measure the distance you've traveled.  More sophisticated vehicles have sensors that measure temperature, driving time and engine revolutions to determine when the oil is getting past its useful life.  Here's one situation where it's easy to see the light.  Do yourself a favor and don't wait too long before coming in for an appointment at Star Auto Service & AC. 

Oh, and driving habits matter, too.  Short trips with a lot of stop-and-go driving will stress your engine and oil more than longer trips at highway speeds. 

And here's one more plus side to getting your oil changed regularly at Star Auto Service & AC in Brea.  Our technician will also keep an eye on the rest of your vehicle to spot anything that might need attention.

The bottom line is this: Oil changes are good for your vehicle in so many ways and probably the most important maintenance service you can get.

Tire or Re-Tire? (Getting Tires Ready for Hot Weather)

Heat isn't easy on vehicle tires, and as the seasons change, make sure yours are ready to take the heat. 

Let's talk first about inflation.  Heat causes air to expand, so heat alone can raise the pressure in your tires.  If you are driving on overinflated tires, they won't have as much contact with the road surface.  In that case, it will take you a longer distance to stop.

On the other hand, you don't want your tires to be underinflated during hot weather, either.  That can cause your sidewalls to flex.  Friction will then hike up the temperature and your tire can be in danger of blowing from the added heat.

Other things can cause problems, such as uneven wearing.  Your service advisor knows the signs to look for and can diagnose where the wear is and what is likely causing it.  Another thing a technician will look for on tires is tread depth and the condition of the sidewalls.  Any cuts, cracks or bulges could be indications that your tire is not healthy. 

Oh, and one other thing.  Your tires could have plenty of tread left on them but still be dangerous.  And that is because rubber ages, gets brittle and cracks after time.  (Ever run across an old rubber band in a drawer that has never been used but breaks the second you try to stretch it? 'Nuff said.) Some tire manufacturers recommend replacing tires after 6 years of their manufacturing date.  Your service advisor can read a manufacturing code and tell you how old your tires are. 

Tire manufacturer Michelin used to have an ad slogan that said, "Because so much is riding on your tires." That includes you and your passengers.  Always keep healthy tires on your vehicle and make sure they're ready for whatever season it is.

Don't be Fuelish (Signs Fuel Pump is Failing)

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.
