Drivers that "T" Us Off (Bad Driving Practices)

We've all seen drivers who do things that—let's be frank—really irritate us.  They're inconsiderate, can put people in danger and make the road a much less friendly place.  They really "T" us off.  These are the bad drivers who fit their description to a "T."  The Tailgater.  You've seen this terrible driver who follows a few inches off the bumper of the vehicle ahead.  We all know what's going to happen if the driver ahead of the tailgater has to slam on the brakes.  And we've all been that driver followed by the tailgater, whose vehicle fills up your entire rearview mirror.  The tailgater is likely not in a great frame of mind and, thanks to his or her stupid driving practices, the "tailgatee" is getting pretty ticked off as well.  That's a formula for a big problem. Know anybody who respects or likes a tailgater? Didn't think so The Texter. All sorts of people think they are perfectly capable of texting while driving.  I ... read more

I Had No Idea! (Four Things You Didn't Know About Vehicles)

Bet you didn't know: Some of the earliest rearview mirrors were marketed as "Cop Spotters" so drivers would know when police were following them. Who wants a ticket, anyway? According to eBay Motors, Elmer Berger first patented a rearview mirror that was mounted on the front fenders, on the spare tire secured to the side of the car of at the top of the driver's door frame.  About 80 percent of your vehicle is recyclable. So says The Balance. That means four-fifths of most vehicles can be recycled.  Much of that recycling is done by automotive aftermarket recyclers.  Between the U.S and Canada, they reclaim enough steel to produce 13 million new vehicles. The man who invented the first modern cruise control couldn't even drive a car because he was blind! His name, says Smithsonian.com, was Ralph Teetor.  Blinded at a young age by a knife accident, Teetor was inspired to create a speed control by a couple of things.  One, the U.S. imposed a mandatory 35 mph/55 kp ... read more

Passing the Test (How to Prevent Emissions Test Failure)

Vehicle emission testing has become ubiquitous in North America and for a good reason.  Clean air quality is important for the environment and all of us.  Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won't needlessly pollute. Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde.  Emissions control systems reduce these gases if they are working properly.  The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key.  So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong. Let's start on the easy one.  Your gas cap could be loose, allowing vapors to escape into the atmosphere.  The most common solution ... read more

No Fueling! (Fuel Filler Location)

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

Not Too Hot and Not Too Cold (Temperature Gauge)

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

If You Drive Like a Maniac (Aggressive Driving is Bad for a Vehicle)

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

Wash Me, Wash Me Right (How to Wash a Vehicle)

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

Cold Weather Vehicle No-Nos (Items to Avoid Storing in a Freezing Vehicle)

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

Weather Station on Wheels (Vehicle Sensor Maintenance)

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

Don't Start with That (Bad Starter Motor)

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
