Can you think of anyone who likes getting a flat tire?  Of course not.  But when one of your tires winds up with a flat or leak, whether it be from things like hitting a curb, running over a nail or picking up a sharp stone, it's time to have someone who knows what they're doing take care of it. If you're thinking you'd like to avoid having to buy a new tire, you wonder if a patch or plug will suffice.  It depends where the puncture is and how big the hole is.  Most tire experts will say if the hole in the tire is less than ¼ of an inch or 6 mm, a patch can work.  But a patch likely won't work if the compromised part of the tire is on its shoulder or sidewall. Here's why.  The shoulder of a tire is the part between the sidewall and tread and it's usually rounded.  It's under a lot of pressure, more than even the sidewalls. And because of that curved shape, it's hard to get a patch or plug to hold. The sidewall is the side of the tire.  Sid ... read more

If your vehicle had something in its design or production that the manufacturer had figured out had an unanticipated problem, you'd want to know about it. And you'd want it fixed. There is something that can help drivers with just such a scenario. It's called a Technical Service Bulletin, or TSB. Here's what a TSB is. Vehicle design and manufacturing is a very complex process. Aftrer every vehicle is introduced, the more units there are on the road, the more likely weaknesses in parts or design will start to show up. Automakers gather data on the issues and how best to fix them. Then they send out TSBs (usually in the first year of the new model) so technicians will know to look for those problems and what to do about them. There may be more than one cause of a problem with a vehicle so there may be more than one TSB for an issue. A TSB can be issued for anything from failing water pumps to strange noises to smelly headliners. A TSB and a recall aren't the same thing. A recall is issue ... read more

It's no fun when your vehicle just doesn't run the way it used to.   You may notice (especially in cold weather) the engine won't start easily or when it does start, it doesn't run smoothly. It may not have much power at all. You also may have had to stop at the gas station more often, a sign your fuel economy isn't what it used to be.  There could be a few different things that cause those symptoms, but one culprit could be a bad ignition coil. The coil takes the voltage from your battery and multiplies it before that power is sent over to a spark plug. That allows the plug to fire off a good jolt of electricity that ignites the fuel in your cylinder and powers the engine.  There's usually one ignition coil for each cylinder (or sometimes for a pair of cylinders). If only one of them is not pushing out enough electricity, it can cause big trouble with your engine performance.  Other signs of a bad ignition coil include engine backfire, an oil leak and your Che ... read more

You know how heavy your engine and transmission are, so you can imagine how tough the parts that hold them onto your vehicle's sub-frame must be.  Not only must they support the weight, they also have to isolate vibrations and noise from the passenger cabin.  Pretty tall order, wouldn't you say? The parts that face that task daily are called the motor mounts, or engine mounts.  They are usually made of rubber with steel brackets.  Others contain a liquid for vibration and sound isolation.  Most vehicles have three or four motor mounts, and while rubber or hydraulic liquids do a good job of damping the vibrations from the engine, they also have their limitations.  The problem with rubber is that it gets old and brittle.  Plus, if there's an oil leak anywhere in your engine and oil gets on the rubber motor mounts, rubber will deteriorate even more quickly.  As for the liquid motor mounts, they can develop leaks and stop working.  Here are sign ... read more

Perhaps you've found yourself driving when something all of a sudden splashes on your windshield, obstructing your view. You know that sinking feeling when you try to turn on the windshield washers and no fluid comes out. Now you're blinded even more. What can you do? The best thing is to make sure your windshield washer fluid is always topped off and ready for these situations. You probably figure you'll grab a bottle of that blue stuff you see in the store. But is that really the right choice? One thing you know isn't the right choice is plain water. It can freeze when temperatures drop. Plus, when it's close to the freezing mark outside, spraying water on your windshield can freeze, turning it literally into frosted glass and blinding you suddenly. Water freezing in your vehicle's washer lines can also damage them. There are different types of windshield washer fluid made for different climates. Many have alcohol to prevent them from freezing; their label will usually tell you at wh ... read more

Hello TRUCKEE! Did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in CA vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission.  It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.If the escaped gases mix with the engine oil in the ... read more

If you've ever had a flat tire, then you know welcome it is to have a spare tire that is properly inflated, in good shape and easy to get to.  Problem is many of us don't even give our spare tire (if we even have one) a second thought. If you have an SUV or truck with a spare, it may be mounted outside the vehicle, such as on the tailgate or underneath the vehicle.  All of them, especially those underneath, take the brunt of debris, moisture, salt and dirt from the road surface, a potpourri of corrosion potential.  The hardware that holds these on can rust into a solid mess, making it hard for you or even a roadside assistance service to get off.  If you have one of those, have it checked and maintained at your vehicle repair facility on a regular basis.  They should be lubricated and cleaned periodically, and some recommend doing this service every time you have your tires rotated.  If the spare is the same size as the tires on the vehicle, it may be a go ... read more

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

With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin.  Some vehicles offer remote starting that let you do that from the comfort of your home or apartment.  But is letting your vehicle idle like that good for it? Manufacturers say it doesn't harm the vehicle.  They say it's because modern vehicles are made differently from those in the past.  Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders.  The engine gets only the fuel it needs, taking conditions into account. Older vehicles, on the other hand, used to use carburetors.  When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions.  Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil. So yes, you ca ... read more

At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving.  But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off! It helps to know the basics of what's happening when you honk your horn.  There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn.  Bingo.  Sound.  When the horn sticks on, one of these parts or the wiring has developed a problem.  With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm.  Try pushing the horn several times; it may un-stick the switch if you're lucky.  If not, there are a couple of things you can try. First, if you can, pull your vehicle off the road and into a spot where you're not disrupt ... read more
