Regardless of whatever current gas prices may be, if you could use less gas, wouldn’t you? Well, here are 10 things that are robbing you of better fuel economy that you can change for the better:    •    Not enough air in your tires.  Underinflated tires have a smaller rolling diameter and more resistance to rolling.  Keep them inflated properly, plus ask us about more fuel-efficient tires.    •    Faulty oxygen sensor.  A faulty or dirty oxygen sensor can cause your engine to burn too rich a mixture of air and fuel.  That can also trigger a Check Engine light.  Have us check yours.    •    Oil age and type.  Contaminated or improper viscosities of engine oil can create more resistance in your engine.  Have regular oil changes and consider newer high-mileage oils.    •    Bad wheel alignment.  When your wheels aren’t lined up straight ... read more

You may have never thought about it, but when you turn a corner, the wheels on one side of your vehicle turn at a different speed than the other side.  What is this magic? The answer is something called the differential.   A differential is a gear box placed between the drive wheels and needs lubrication to work.  Over time, that fluid can become contaminated, reducing its effectiveness. You likely won’t be able to detect any signs that it’s happening, though it may get a little noisier over time.  If you continue to drive with contaminated and degraded differential fluid, the gears may wear prematurely. That can also contribute to excess wear on the drive-wheel tires.    Two-wheel drive vehicles have one differential while all-wheel and 4-wheel drive vehicles will have two or three.   Your vehicle’s manufacturer has guidelines on how often you should have the differential fluid changed, and we recommend you follow those.   Chan ... read more

When you’re driving and you hear a squeal or groan when you turn, it may be a sign your power steering pump is on its last legs.  The same is true if you feel your steering is slipping or doesn’t respond to your hands like it used to.   Precise, responsive steering is, of course, important when it comes to safe driving, so this is something you should have one of our technicians look at sooner rather than later.   There are different types of power steering pumps, and they all perform a similar function.  They make it easier for you to turn the steering wheel with little effort as the power steering system multiplies that force so you can precisely aim a vehicle that weighs thousands of pounds.   The type of power steering pump your vehicle has depends on the power steering system it uses.  One works by hydraulics, taking energy provided by belts driven by the engine which pressurizes power steering fluid to the wheels.  There are a lot of ... read more

Your vehicle has a few filters you might be somewhat familiar with.  There’s the oil filter that removes impurities from your engine’s oil, and a couple of different kinds of air filters that prevent contaminants from getting into the engine and the cabin. But you may not know that your vehicle also has a fuel filter. The fuel filter keeps contaminants such as particles and other foreign substances from making their way into the engine.  They can result from using lower quality fuel, driving in dirty or stop-and-go conditions, or simply what happens after many weeks and months of travel.  At some point, your fuel filter will start to get clogged up and won’t let the fuel get to your engine easily.  You might notice some signs of that: your engine doesn’t have the power it used to, it may misfire when you accelerate, it may be harder to start, or it may stall while you’re driving.  You may notice your vehicle vibrating a lot when yo ... read more

What do mud, bird droppings and frost all have in common? When they’re covering your windshield, they can temporarily obscure your view of the road, leaving you driving blind.  And when you can’t see the road clearly ahead of you, it can be really scary.  That’s one of the reasons it’s important to maintain your windshield cleaning system, which includes your wipers, blades and washers.  They’re three vital components that work together to ensure you’re clearly seeing what’s going on with the road and drivers around you. Your wipers are doing the physical work on the surface of your windshield’s glass.  The rubber or silicone is what touches the surface of the glass, and after time and exposure to the elements, wiper blades can get brittle, lose their flexibility, rip and tear to the point where they simply can’t clear the glass.   What holds the wiper blades close to the glass is important, too.  Conve ... read more

It’s always a good idea to keep your cool, and that’s especially true when it comes to some components of your vehicle.  One is the engine.  It’s hot under that hood thanks to the mini explosions that are occurring in the internal combustion engine when it’s running.  Your vehicle has a cooling system which takes the heat out of the engine by moving a liquid coolant to a spot where the heat can escape (the radiator).  The part that keeps that coolant moving is the water pump, which could probably be more accurately called the coolant pump since water is only one component of the fluid that does the cooling. If the water pump fails, your engine can overheat quickly, and that can cause significant and expensive damage to your vehicle.  Water pumps can be driven by belts (mechanical) or electricity (electric). Your vehicle’s manufacturer recommends mileage intervals when you should consider replacing your water pump even if seems to b ... read more

One of the hardest working components of your vehicle is its transmission, shifting gears up and down when you need it to.  The transmission is vital to your vehicle driving properly, and if you start to see signs of problems in it, it’s best to have them fixed earlier rather than later. (Since nearly all new vehicles have automatic transmissions, we’re leaving manual transmissions for another time since their issues are different.) One sure sign your transmission has a problem is when you notice it’s not changing gears like it used to.  Or perhaps you observe when it does change gears, they slip when you are driving.  Gear change problems could be as simple as something wrong with your transmission fluid, but it could be more serious, so get this one checked out soon. Another trouble sign is when you feel your transmission shaking and vibrating as you’re accelerating, decelerating or trying to maintain a constant speed. Hearing odd noises when yo ... read more

When you are comfortably headed down the road, you may not realize how many of the imperfections in the driving surface are being smoothed out, so you hardly feel most of them.  You can thank your shock absorbers for a lot of that comfort, and it’s important to make sure you keep your shocks in good shape. Newer vehicles have shock absorbers in the back wheels with another shock absorbing assembly in the front which may also have a spring component as well, called struts.   Shock absorbers not only keep your vehicle traveling smoothly and comfortably, but they also contribute to its stability.  Increased stability will help you be able to handle sharp turns and sudden stops more easily.  Shocks also prolong the life of your tires because they’ll grip the road more tightly.  And a nice side benefit of that is your tires should last longer.   After months hitting a lot of bumps on uneven road surfaces, eventually your shock absorbers will start t ... read more

When you see some liquid sitting underneath your vehicle, your mind starts churning.  Is that normal? Is that something serious, or did I just spill my drink? Here’s a quick list of what those fluids look, smell and feel like, as well as what they might be. No, we don’t recommend you taste them to verify.    •    Clear and underneath your air conditioner or under the end of your tailpipe. It’s likely something as simple as condensed water.  This probably doesn’t need immediate attention, but you should keep checking periodically.
   •    Oily, brown, golden or black.  That could be the sign of engine oil leaking.  Oil may also smell if it has been leaking on metal and burning.  This is one you should have checked out fairly quickly.
   •    Green, blue, red, yellow, purple or orange and watery under the engine.  Smells sweet.  May be coolant (antif

When it comes to brakes on your vehicle, we all know how important it is to keep them working well because they are vital safety equipment.  After all, if you can’t slow down and stop, you can’t drive safely.   While many vehicles use what are called disc brakes, there’s another type of brakes that are used on the rear wheels of vehicles that have something called drum brakes.  Drum brakes were the original type that were invented in the early twentieth century.  The term drum comes from the part of the brakes that is a housing connected to your wheel.  Inside there are parts called brake shoes that press against the drum when you step on the pedal, and the friction slows and stops your vehicle.   Signs your brake shoes might need replacing are your rear brakes make noise when you step on the pedal and they vibrate when you brake.  Another sign of bad brake shoes is that your hand brake stops working.  If you notice one or both ... read more
