Why did my vehicle fail its emissions test?

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

Bump in the Road (Alignment)

There's something you can do that helps your tires last longer, wear more evenly and your vehicle handle better.  "Sign me up," you say! Wondering what that is? It's aligning your wheels, and it will literally point you in the right direction when it comes to a better and safer driving experience. When your vehicle was designed, the engineers made sure your tires were all pointing the same way by designing the suspension to make optimal contact with the road. That way the ride is smooth, you don't feel vibrations or shimmying and your vehicle travels in a straight line, without pulling to one side or the other. Unfortunately, your vehicle is not brand new; time and distance take their toll.  After hitting countless bumps, potholes, or the occasional curb, your suspension gets knocked a little out of kilter.  Those precise angles the engineers planned on for your vehicle? They get out of whack Uneven or premature tire wear is one of the first signs your alignment may be o ... read more

Lubricate Driveshaft

See if any of these are happening to your vehicle.  You feel it vibrating excessively underneath when it’s running, or you hear strange clunking, grating, or grinding sounds coming from beneath.  Maybe it’s hard to turn your vehicle, or you can hear squeaking when you’re going slow.  Perhaps you feel a shudder when you step on the throttle.   Any of those could be signs that your vehicle’s driveshaft might need lubricating, and it’s important to have one of our technicians check it out. Your vehicle’s engine puts out a lot of twisting power.  That force is called torque, and the driveshaft is the part that handles the job of transferring all that torque from your engine to the wheels.  If it’s a four-wheel or all-wheel drive vehicle, it will have driveshafts front and rear.  Some driveshafts have different segments which are connected by couplings called U-Joints.   So that everything can glide along fine ... read more

Timing is Everything (Timing Cover Replacement)

There’s an important part in your vehicle that shields your timing belt, timing chain or cam belt from the debris and gunk that can be kicked up from the road.  It’s called the timing cover.  It’s important because the timing belt or chain is what coordinates parts of your engine called the camshafts and crankshaft.  When they’re in sync, all runs smoothly.  When they’re not, it can cause some serious engine problems. If your vehicle has a timing belt, without the protection of the timing cover, that belt can come loose from the timing gears or break.  If your vehicle has a timing chain, the cover keeps engine oil circulating around it which lubricates it.  When that starts to leak because of a bad gasket, the chain may not be getting adequate lubrication.   If your vehicle has a timing cover problem, you may notice engine oil leaking if a gasket is not sealing tightly.  You may hear a strange metallic sound coming f ... read more

Putting a Stop to Brake Problems (Brake Service)

It's safe to say that most drivers take their brakes for granted.  You press on the brake pedal and the vehicle slows down or stops.  It's easy to see why it is so important for your vehicle's brakes to be working correctly.  Brakes are an important safety feature of any vehicle. When it comes to your brakes working correctly, maintaining them regularly will ensure that you will always be able to slow or stop your vehicle in any situation, whether on a sunny day on dry pavement or a bad weather day on slippery surfaces.  And that is why regular brake service is such a sound investment for all drivers. The combo of brakes" and "surprises" doesn't usually end well. You might already know about some of the parts of your braking system.  Terms familiar to you might be pads, rotors, and calipers. In short, the calipers press the pads, which in turn contact the rotors.  The resulting friction slows your vehicle.  Another type of brake uses a drum and brake ... read more

Do I Need Brake Service? (Brake Service)

Think of how many times you put your foot on your vehicle’s brake pedal every day.  And think of how much you rely on your brakes to slow down and stop your momentum.  When it comes to safety systems, your brakes are at the top of the list, and that’s why it’s so important to keep them in top condition. Brakes are something you make sure you keep maintained before they start showing signs of problems. Some of those signs are a grinding sound when you step on the brake pedal, your vehicle pulling to one side when you brake, you don’t feel your brakes stopping you as quickly as they used to, or you notice the brake light is illuminated on your instrument panel.  We ask a lot of our brakes.  They have to work no matter how hot or cold it is outside.  That means whether it’s sunny, snowing, raining, or icy; you’re traveling at highway speeds or school-zone speeds; or when suddenly you find yourself trying to avoid hitting another ... read more

Motor Oil?The Synthetic Advantage (Synthetic oil vs Conventional)

You’ve probably already heard that regular oil changes are extremely important for the health of your vehicle’s engine. That’s sound advice.  But what you might not know is when it comes to motor oil, the real thing may not be the best thing for your engine. There are different types of motor oil:
•    Conventional oil, extracted from the ground and refined.
•    Synthetic oil, manufactured from high-quality base oils and artificially-made chemical compounds.
•    Synthetic oil blend, a mixture of conventional and synthetic oils. The first thing you need to know is that most new engines require synthetic oil.  If synthetic oil is recommended for your car – you MUST use it. For the rest, there are many advantages to using synthetic oil over conventional oil.  •    Synthetic oil provides better protection for your engine while helping it to perform better.
•    Co

(Timing Belt)

You may have heard about an important part of your vehicle's engine called a timing belt, and many know that if that belt breaks, it can cause some very serious engine problems.   Not all vehicles have them, and the ones that do generally have smaller engines.  The timing belt keeps the engine synchronized so that every time a spark plug fires, the crankshaft, camshaft, pistons, and valves are all working together.  Timing belts will eventually have to be replaced, and most vehicle manufacturers recommend when that should be.  Typically, it's around every 60,000-100,000 miles, or 100,000-160,000 km. It's a good idea to stick to your vehicle's schedule or be alert for signs that the timing belt may be failing prematurely. Some of those symptoms? Maybe your engine won't even turn over when you try firing it up. You might hear a ticking or banging sound under the hood.  Perhaps you spot an oil leak or notice the engine misfiring.  If any of those are happenin ... read more

Full Stop (Brake Master Cylinder Replacement)

When you step on your brake pedal, you want to feel confident that your vehicle’s going to stop.  If your brakes aren’t working right, it’s a risk to your safety and the safety of others on the road.  After all, you’re driving a machine that weighs thousands of pounds, and you have to be able to stop that big machine quickly and with control, especially with some of the speeds you travel on the highways.  The heart of your vehicle’s brake system is the master cylinder.  When you apply the brakes, the master cylinder has pistons, springs, and brake fluid.  That fluid amplifies and distributes the force of your foot through brake lines to calipers at all your wheels.  Those calipers squeeze down on rotors or discs, which is what slows down and stops your vehicle. For safety, a master cylinder has two cylinders, one for two wheels, and the other for the remaining two wheels.  That way, if there is a failure in one, you&rsqu ... read more

Flat Tire? Three?s the Charm (Tire Repair)

For most drivers, at some point you’re going to have a flat tire. Depending on how it was damaged, it may have to be replaced.  But sometimes, a repair will do the trick, as long as the puncture isn’t on the sidewall and the hole is smaller than ¼ inch/6.35mm in diameter. Here are the three common ways your tire can be fixed. One way is to put a plug in the hole.  Since most tires are damaged by running over sharp objects such as screws and nails, the small hole from which the air is escaping is on the part of the tire that touches the road. If it’s in the sidewall, it most likely can’t be fixed.   In the plug method, a technician inserets a rubber plug.  It is covered with some sticky, gluey stuff, and is pushed into the hole from the outside. That plugs the hole and stays in place, thanks to the glue. Friction from driving heats it up and seals the deal.   Another method is to patch the hole.  For this, your tire has to fir ... read more
