We all want to breathe clean air and keep our planet green.  One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test.  That’s because these vehicles can be big polluters.   Everyone wants their car to pass the test so they can continue their day-to-day driving routine.  But then comes that one day when they tell you your vehicle has failed.  Why does that happen? One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!).  The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go. Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air.  There are many reasons the catalytic converter may not ... read more

Shopping for tires in San Diego can be bewildering because there are many choices. Let's simplify. There are four main classifications of tires, each designed for different purposes.First off, there are summer tires. Those who buy summer tires in San Diego are looking for maximum summertime performance. The rubber is a little softer to help stick to the road on fast corners on CA roads. The tread has wide blocks at the shoulder to stiffen the tire in turns. The tread design can handle rain but really isn't set up for snow and ice. Next comes winter tires. San Diego people buy winter tires because they still like performance driving when it's cold and slippery on CA roads, so they need a tread design that'll really bite into ice and snow. The rubber compound is formulated to stay pliable when temperatures drop below 45 degrees F/7 degrees C so they get great traction even on dry roads. On the other end of the winter tire spectrum are tires designe ... read more

Ever wonder how your vehicle’s engine is able to take the 12-volts from its battery and ramp that up to as high as the tens of thousands of volts it takes to fire its spark plugs? The secret is something called an ignition coil.  Most newer vehicles have an ignition coil at each cylinder, but older ones have a coil that serves all of the spark plugs.  There are telltale signs that you have an ignition coil problem.  As you might expect, one symptom is it’s hard to start your engine or it won’t start at all.  If your engine is misfiring or not running smoothly or you see the Check Engine light come on, those all could point to an ignition coil failure. Several things can contribute to ignition coil trouble in addition to normal wear and tear. Moisture and dirt may have gotten inside the coil, plus the heat and vibration of your engine over time can contribute to them going bad.  Bad spark plugs or plug wires can also be a cause.   While ig ... 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

Ever wonder how your vehicle’s transmission is connected to your wheels? After all, when you hit a pothole or some other uneven part of a road’s surface, there has to be something that can maintain the connection between the transmission and the wheel yet keep everything moving at the same speed.  That very cool device is called a CV joint, a kind of driveshaft running to each wheel.  The CV stands for constant velocity because it keeps the drive wheels moving at a constant speed (velocity).  They’re used mostly on front-wheel drive vehicles but also in rear-wheel and all-wheel drive vehicles. The joints move up and down and adjust to bumpy surfaces.  Plus, they are covered in a rubber boot which protects them from road debris and also holds lubrication in.  There’s a CV joint and boot on the transmission side and one on the wheel side.  Unfortunately, the spot that usually fails first is that rubber protective cover (the boot).&nbs ... read more

Most drivers love how easy it is to turn their vehicles, and they have power steering to thank.  Engineers have figured out a way to take some of your engine's power to help you turn. Without it, steering can be quite a chore.  New power systems are electric, but there are still plenty of the older hydraulic power steering systems out there, and it's wise to keep them working the way they should so you don't find yourself stranded without power steering. Those hydraulic power systems use a fluid under pressure that is pumped to a device that helps you turn your wheels more easily.  It's that pressure that presents the challenge.  After your vehicle's seen a few years on the road, you may find your steering isn't quite as easy as it was.  You may hear a groaning or humming sound when you turn.  One component that can fail is the pressure hose that carries that fluid from the power steering pump to that turning assist mechanism.  The hose is made of rub ... read more

You know that sinking feeling when you realize one of your tires has a problem.  It may be making an odd noise or behaving oddly when you're driving.  You may hit a pothole or curb and one suddenly goes flat.  Or you may head back to your vehicle and discover it has one tire deflated without a clue of what must have happened to it. With a lot of different tires hitting the streets these days, the issue of whether to have a tire repaired or replaced can be tricky, and we strongly recommend you have a trained technician help you make that decision.  One of the most common causes of flat tires is picking up a screw or nail in the tread area.  Many of those can be patched and plugged if the puncture isn't more than ¼ inch/6 mm in diameter. Most tires can handle two of this type of repair, but any more and you should buy a new tire.  If there's a puncture or bulge in the sidewall or shoulder, the rule of thumb is it's not repairable.  The sidewall d ... read more

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

If you have a front-wheel-drive vehicle, it has components called CV joints which enable you to turn your wheels smoothly. The CV stands for “constant velocity.” In essence, it’s a set of gears that connect a shaft that allows power from the transmission to be sent to the wheels.  When you turn the wheels, no matter what angle, the input velocity rotation will be equal to the output. Thus, the name, CV (constant velocity) joint. Other vehicles with 4-wheel drive and all-wheel drive also use CV joints.   If one of your CV joints isn’t working right, you may find your vehicle difficult to handle.  If one breaks, your vehicle may stop moving.  So, it’s important that CV joints be in top working condition.  The joints need a lot of lubrication, so they are surrounded by grease.  There’s a rubber enclosure around them called the boot which holds the grease in and protects CV joints from the elements.

In a year marked by unusually heavy flooding in North America, drivers are very aware of the possibility they may find themselves driving where water has come over the road.  It can be a daunting and frightening situation.  Flooding waters can move quickly and unpredictably, so you have to keep your wits about you when you encounter that situation. Here a sample of one vehicle manufacturer's guidelines on what to do.  First, the vehicle is designed to go through some water, but you must be careful.  Never attempt to drive through water deeper than the bottom of your tires. You can get out of your vehicle to check the depth of the water, but you can never be sure that you aren't going to drive into a spot where the road has washed away.  You can't see below the surface of the water, and suddenly you could find yourself in a place where the road drops off unexpectedly.  In swift moving storm runoff, your vehicle could literally be floating away with the curr ... read more
