Gas Smell! (What Causes Gasoline Odors)

If you've ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents.  There are many things that can cause a vehicle to give off a gasoline odor.  One of the easiest to track down is the gas cap.  It could be missing or it doesn't seal well any more (they do wear out).  That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis. Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It's the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they're made out of rubber or metal).  They can leak gasoline, too. It's always a good idea to check the garage floor for any gasoline puddles.  Note the location of the puddle in relation to ... 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

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 Byte Stuff (Your Vehicle's Computers)

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception. The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit.  But it's not just the diagnostics that are computerized.  Everything from your vehi ... read more

THE IMPORTANCE OF VISIBILITY (Cleaning Vehicle Glass)

We've all been through it. The vehicle ahead of us kicks up mud, slush, snow or salt on our windshield and we can't see a thing.  And not being able to see a thing when we're driving?  Not a good thing. Debris on a vehicle's glass can be blinding when driving directly into the sun.  And other things can ruin visibility: scratches on the glass, fogged windows, mineral deposits.  So lets make one thing clear:  Your windows.  Here are some tips. Number one rule, don't use abrasives on glass. That means no gritty cleaners that are made for metal.  Avoid at all costs those dark green abrasive pads on some kitchen sponges that are made to clean metal pots and pans UNLESS the manufacturer specifically says they can be used on glass. Use the appropriate cleaner for the substance that's being cleaned off. Special automotive glass cleaners are available, and your John's Automotive Care service advisor can make recommendations. Vinegar can work wonders. Sometim ... read more

Out with the Old (Vehicle Parts that Wear Out)

Some drivers don't pay any attention to their vehicles until something breaks.  Others take them into their service repair facility for maintenance even before a problem develops.  Still, even if you fit into the second group, there are some parts on a vehicle that will simply wear out over time. Your vehicle has gaskets in several places.  They use a flexible material to seal the gaps between metal parts that fit together. After time, that material shrinks or gets brittle and fails.  Eventually, after time, you will have to get gaskets replaced. Same goes for belts.  Your engine has belts that help take the mechanical energy of the engine to drive other parts such as the generator and air conditioner.  Heat and age will eventually cause these belts to wear out or break, so you'll need new ones at some point. You'll also find yourself buying brake pads.  As much as you may try to go easy on them, brake pads work by wearing off a little bit of them eac ... read more

The Key Won't Turn! (Ignition Problems)

You've just arrived at the store shopping and you're ready to head home.  You put your key in the ignition and… oh, no! The ignition won't turn! What do you do now? Don't panic.  There are some things you can do to get going again.  The first thing to do is see if you have a locking steering wheel, an anti-theft feature that was introduced around 1970.  Sometimes it sticks.  Move the steering wheel side to side while you try to turn the key and you might be able to get it to release.  Another thing to check is to see if your vehicle is in gear.  Most vehicles will only allow you to start the ignition if it's in park or neutral.  If you have an automatic transmission vehicle and it is in park, try jiggling the shift lever and try the key again.  Sometimes the safety mechanism doesn't properly make contact or gets a little sloppy.  If both of these don't work, it could be your vehicle's battery is dead.  Some newer electronic ... read more

DOG FOOD IN YOUR ENGINE (Keeping Rodents out of your Engine)

A technician was telling us the other day that he was servicing an engine and spotted something he'd never seen before: A collection of dry dog food siting on a horizontal metal ledge near the base of the engine.  It was neatly stashed and was in a spot where the food pellets couldn't have simply fallen down in there. Even though it's the first time he'd seen dog food in an engine, he immediately knew what was going on.  Critters like mice or chipmunks had found the dog food somewhere nearby and had used the engine as a nice storage unit.  Mice, squirrels, chipmunks—you name it—like the heat of the engine.  And they'll use that to store up supplies of food for use in cold weather when outside food supplies are scarce.  The problem is they'll also chew on engine components while they're there. And they can do a lot of damage if they start gnawing on the wires.  Depending on how much of your electrical system needs to be replaced, repairs can mou ... read more

The Best Book that's Not a Best-Seller

Sometimes the movie is better than the book, sometimes it's the other way around.  But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance. And yet, it's amazing that some people will own a vehicle for years and never even crack this book.  They'll only read it when they absolutely have to, for things like finding out how to change the clock.  Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover.  We know that.  But just think of what you can get out of it. Consider this.  Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it.  They know more about your vehicle than anyone, period.  They know how long a part is likely to last and what ... read more

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
