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 ... read more

What's in a Number? (What Tire Numbers Mean)

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

Rear Window?Not the Movie! (Why Some Rear Windows Don't Go All the Way Down)

Alfred Hitchcock once made a mystery thriller film called "Rear Window." It had nothing to do with the rear window of today's cars, SUVs, CUVs and light trucks.  But there is one thing that some drivers DO find mysterious.  Why don't the rear windows in the second row of many of these vehicles go down all the way? You've probably seen or owned one or two. That rear side window only goes down about a third, a half or three-quarters of the way. Yet there are some similar vehicles where the window goes down all the way.  What gives? There was the rumor going around that the restriction on how far those windows could go down was a child safety feature.  The thought was that if those windows couldn't open up fully, a child (or pet) would be less likely to fall out.  But it turns out the real reason is that the way the rear doors were designed, there was just no room for the window to go down all the way into. Many vehicles are configured so that the rear wheel arch ... read more

Unlock the Secret (Malfunctioning Door Lock Actuator)

What a convenience power door locks are on a vehicle.  The latest don't even require you to push the button on the key fob; all you have to do is have it with you.  But sometimes there's a component of power door locks that can fail, especially when they are used several times each day.  Those are called the door lock actuators. The actuator is an electric part that works with others (like motors and gears) to lock and unlock doors.  You can hear them work, sometimes with the little whirr of the gear or the quiet clunk of the lock finishing its cycle.  And it's good to pay attention to that sound because if it starts to sound different, it could be a signal that your lock is on the brink of failing. Another sign of a failing power door lock actuator is they start working intermittently or quickly and erratically.  The driver's door is often the first to start acting up since it's the one that usually gets the most use. When you start to notice these signs ... read more

A Cool and Smooth Transmission in San Diego

When it comes to preventive maintenance on our vehicles, most of us San Diego drivers remember to get our oil changed. But services that occur at longer intervals — like transmission service — sometimes get overlooked. Yet transmission service is part of car care. A poorly maintained transmission will fail and lead to repairs.The transmission transfers power from the engine to the drive wheels. When it's clean and well-lubricated, it gives maximum fuel efficiency. But when it gets dirty or worn down, your transmission will suffer. Your transmission relies on transmission fluid to keep everything running well.This is why the transmission fluid must be changed periodically. Your owner's manual will give you a recommended time schedule for this service. Or, you can ask your friendly and knowledgeable John's Automotive Care service advisor. Generally, the interval is around 35,000 miles (55,000 km) or every two years. But the interval for your vehicl ... read more

Fuel for Thought

If you're like most people and drive a gasoline-powered vehicle, you need to be up to speed on its fuel-related components.  They're pretty basic: the fuel, the fuel filter and the fuel pump. The fuel's the easy part.  You probably gas up your vehicle yourself and, if you're like most drivers, price is a big factor in what you put in your vehicle. Maybe you think it doesn't matter what kind of gasoline you buy, but one major automobile association has found it does make a big difference.  Their study showed that the additives that are put in different brands can affect your vehicle's performance.  Certain gasoline retailers sell gasoline that meets performance standards called Top Tier.  The detergents used in Top Tier gasoline help protect newer engines from carbon buildup and deposits on intake valves, all things that can affect how smoothly your engine runs, how it accelerates and what kind of fuel economy you get.  You can check online or ask your serv ... read more

NOT JUST ANOTHER CUSTOMER (Finding the Right Service Facility)

You might remember a hit TV sitcom that was set in a bar, a place where "everybody knows your name."  The idea, of course, is people feel more comfortable where they aren't just another customer among many; they're special because their relationship goes back a few years.   That comfortable relationship can extend to professionals you deal with, too.  Think of your accountant, your dentist, your doctor.  Most people try to stick with the same person or firm in those businesses.  They have grown to know their work over the years and they've learned to trust their professionalism, the quality of their work and their track record.    Ideally, you should have that same relationship with your automotive service facility, like your friends here at John's Automotive Care. You may have tried several facilities over the years until you found one that did good work at a reasonable price.  The longer your relationship with your service facility, the better ... read more

The Power Behind your Engine (Alternator Diagnosis and Repair)

There's nothing like that sinking feeling when you turn the key and nothing happens in your vehicle.  A lot of us are quick to blame the battery.  But it may instead be your alternator that's failing. Your battery supplies power to start your vehicle, but the alternator is what sends power when your engine is running.  The good news is alternators last a fairly long time, and it's not unusual to get seven years out of one. But they can give up the ghost thanks to the harsh conditions in the engine compartment. Alternators have bearings inside them that keep things turning smoothly.  Debris, liquid, dirt and more can team up with the high temperatures your engine generates to cause those bearings to seize up.  That's not good, and if that happens, you may even be able to hear the bearings grind. Other symptoms of a dying alternator are a squealing noise in the engine compartment or your headlights may go dim and bright, dim and bright.  You might even notic ... read more
