If you've ever gotten in an unfamiliar vehicle, maybe a rental car, you may have pulled up to the gas pump and wondered, "Which side is the fuel filler on?" Here's a tip for you.  There is usually a little arrow on the instrument panel near the fuel gauge that points to the side where the fuel filler is.  But why are the fuel fillers not all on the same side, anyway? There are lots of reasons.  At one time, many manufacturers tried putting them in an easy-to-reach spot: in the center of the vehicle's rear end.  Some even hid them behind a hinged license plate door.  Cool place, but it turned out not to be a good idea.  When a vehicle with a fuel filler in the rear was hit by another vehicle from behind, it was much more prone to catch fire and explode. Safety regulations now dictate that the fuel filler doors be placed within crumple zones and away from where they can drip fuel on hot exhaust pipes or near electrical connections.  But why do manufactu ... read more

You know your body temperature is supposed to be 98.6 degrees F, 37 degrees C.  Your vehicle has a normal temperature, too, and if you pay attention to it, that can save you some big headaches down the road. Many vehicles have a temperature gauge on the dash that takes the temperature of the engine's coolant.  Some have a thermometer symbol, some read C-H (cold to hot). Many will have a red zone that shows when water temperature is getting into the danger zone.  Others are digital and have a red warning light that signals overheating.  And some vehicles have a light that goes on when the engine temperature is out of the normal range. If your vehicle has a gauge, pay attention to it.  If you need help locating it, ask one of our John's Automotive Care experts to give you a quick explanation.  Chances are when the vehicle has been running for 15 minutes or more, the temperature gauge will settle into its own "normal" zone, often just below the midway point ... read more

When someone mentions driving like a maniac, they're not talking about you, surely? Besides the safety issues of aggressive driving, you should know that your vehicle will last a lot longer if you'll just mellow out a little.  Here are four traits good drivers follow if they want their vehicles to go the extra distance. Cool—The driver who can't wait to get to the next stoplight is just shortening the life of his or her vehicle.  Jackrabbit starts and uneven acceleration hurts your engine because the valves and cylinder heads are stressed more.  All of those moving parts will wear out faster as well as other components that are connected.  That means things like the air conditioner, power steering pump… just about anything that attaches by a belt or a pulley.  Oh, and you'll be generating more heat.  Heat is one of a vehicle's worst enemies. Warm—If you get in your cold vehicle which has been sitting overnight, start it up and rev the en ... read more

Most would agree they'd rather drive around in a clean, shiny vehicle than one coated with a layer of dirt.  When warmer weather comes around, some of us are bound and determined to wash our own vehicles.  And to protect the paint and its luster, there are a few things to keep in mind when you get out the bucket and soap. Cool body.  It's not a good idea to wash a vehicle when the body is hot.  If it's been sitting out in the sun or you've been riding around on a sunny day, make sure you cool your vehicle off by either moving it to the shade or wetting it down with cool water. The problem with washing a hot vehicle is that it's going to dry so fast, minerals in the water can form hard-to-remove spots on the paint.  And some of those can be really difficult to get out.  Best to avoid it. Slippery when wet.  Make sure you wet your vehicle down thoroughly before you get the washing mitt out.  Experts keep a couple of buckets of soapy water on hand ... read more

It's always easier to leave a few things in your vehicle so you'll have them on hand.  But in cold weather, while it's a good idea to carry items such as a phone charger, blanket and shovel, there are some things you shouldn't store in your vehicle. Medicines and drugs.  Cold temperatures can affect the chemical makeup of some drugs.  Avoid leaving them in a vehicle, especially those in a liquid form like insulin, eye drops and cough syrup. Latex paint.  They are water based, and when they freeze, they get lumpy and lousy.  Your paint job will not be what you had in mind. Cellphones and computers.  Most of these have lithium ion batteries.  If they get colder than freezing (0 degrees C, 32 degrees F), if you try to charge them, you'll more than likely ruin the batteries.  Bottled water, soda, wine or beer.  OK, here's the scoop.  All of these can freeze and split the container they're in.  Yes, soda, wine and beer will take a lowe ... read more

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool. First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond. Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient tem ... read more

We've all heard that expression, "That's a non starter." When it comes to your vehicle, that's not music to a driver's ears. That sickening sound when you start the ignition and instead of hearing the engine crank, you hear it slowly turn over and your dash lights go dim.  There can be many reasons a vehicle won't start, so here's a little history of how the starter came to be an important component of modern vehicles. You have to move the engine's components to start it. The first cars had a crank that the driver would insert into the front, then start turning things over by hand.  When the engine started, you had to release that crank immediately or risk a broken arm.  Yes, it happened many times.  So, they came up with a better idea: an electric starter, which was a big advance in automotive technology. With this system, an electric motor rotated a series of gears that turned the gasoline engine's crankshaft so its pistons and parts moved and the engine drew in a ... read more

When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades.  You have spark plugs that require enough power so a spark can jump across a gap at its tip.  Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing. The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off.  That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers.  Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers. The next evolution came in the 80's when the distributor ... read more

There's a gauge that many vehicles have that says RPM on it.  And there are a lot of people who either don't pay any attention to it or don't even know what it is. Here's why it's a good gauge to know about. It's called a tachometer, and that "RPM" label means it is measuring how many revolutions per minute (RPM) the engine is turning.  Automotive experts know that a vehicle's engine can be damaged if it turns too fast (revving too high) or too slowly ("lugging" the engine). A tachometer (sometimes called a tach) is almost a "must-have" gauge for vehicles with a manual transmission; the driver has to manually change gears; the tach helps the driver know when revolutions are in the optimal range. Some say you don't need a tachometer if you drive a vehicle with an automatic transmission. It's true that most drivers of automatics don't even look at it.  But there are times when paying attention to the tach can help you prevent an expensive repair. Here's a good example.&nbs ... read more

This may have happened to you.  You drive somewhere and get out of your vehicle only to try closing the door and it just won't stay closed!  What a helpless feeling.  You can't lock it; you can't leave it like it is. Or, let's say you head down to your vehicle to head out to work in the morning and you can't open the door.  What are you going to do now? Vehicle doors take a lot of abuse.  They are opened and closed hundreds of times and we expect them to just keep working perfectly all the time.  They do require a bit of tender loving care.  Let's take a look at two different scenarios of stuck doors. First: the door that won't close.  It's a security issue.  It's also a safety issue.  You can't really safely drive a vehicle with a door that won't close. What if you or a passenger is tossed out?  Sure, some people try to tie a stuck-open door closed or bungee it, but that's dangerous.  It's best to get that vehicle to the serv ... read more
