Making Sense of the O2 Sensor (Oxygen Sensor Replacement)

As you know, today’s vehicles rely on a lot of computers in them to keep them running clean and efficiently.  Those computers depend on information delivered by several sensors throughout the engine and exhaust system.  And one of the most important is the oxygen sensor.   Known as the O2 sensor for short, it looks for too much unburned oxygen that has made it into the exhaust. That signals something isn’t right with the engine’s air-fuel mixture.  The sensor sends signals to the engine’s computers, which can then make adjustments to make sure the engine is running as it was designed to. Some vehicles can have several O2 sensors, and since they can measure oxygen at various points in the combustion/exhaust process, the computers can pinpoint where the problems lie.  For example, an O2 sensor can detect how much oxygen is coming out of the engine’s combustion chamber, and another one can measure oxygen coming out of the catalytic co ... read more

Steer Clear (Power Steering Pump Replacement)

When it comes to ease and precision of steering, today’s vehicles are engineering marvels.  One of the keys to just how good steering is lies in the refinement of power-assisted steering which we know simply as power steering.  At the heart of the system is an electrically or belt-driven power steering pump.  It can apply hundreds of pounds of hydraulic pressure to the steering gear so you can turn your heavy vehicle with little effort. The more time and distance your vehicle travels, the more wear your power steering pump experiences. One sign your pump may be aging is that you hear a whining or groaning sound coming from your wheels when you turn. You also may feel a vibration through the steering wheel, or the wheel is harder to turn or responding more slowly than normal.  Another sign of trouble with the power steering pump is power steering fluid (reddish-brown) leaks on the ground around your vehicle. If you encounter these symptoms, have us check your v ... read more

Beginning to See the Light (Check Engine Light Diagnostics)

It's a light many drivers fear they'll see turn on at the most inopportune time.  It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine. The truth is that Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine.  Don't ignore it because it's there to help you avoid an expensive repair it is designed to alert you to, to tell you something's not quite right. Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light. If it's flashing, that could be serious. Look at some of the other warning lights or gauges such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right ... read more

Why Maintaining Your Windshield Wipers and Washers Matters (Windshield Wiper and Washer Inspection)

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

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

I Want a New Vehicle. Or Do I? (Vehicle Maintenance Payoffs)

Spring is a peak season for vehicle sales; companies aggressively market new models and offer all sorts of incentives.  So you may be tempted to buy a shiny new beauty.  But should you? If you've regularly maintained the vehicle you're driving now, you probably don't NEED a new one.  Even if your current one needs some repairs, how do those costs compare to what you'd spend on a new vehicle? A brand new vehicle starts to depreciate the second you drive it off the lot. How much? Experts say you'll lose half of its value during the first 5 years of owning a new vehicle. So if you pay $30,000 for a new one, you'll lose $15,000 in 5 years.  That's a lot. If you have paid off your current vehicle, think of having to start making car payments again.  Let's say your new payment would be $350 a month.  Bet you can think of a lot of things you can buy with an extra $350 a month. Many considering a new vehicle don't factor how much their insurance and license tag fe ... read more

Not-So-Common Sense (Sensor Failures)

So your vehicle won't start.  What's the first thing that comes to mind?  Battery dead? Starter motor worn out? Out of gas?  Well, those are all reasons that make sense.  But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it.  Here's how that works. You have lots of computers in your vehicle.  They need to know the status of things so there are several sensors monitoring various things going on.  These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel.  They know when things aren't quite right and prevent you from starting your engine if that's going to damage it.  Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly. Here's an example of a sensor doing its job.  Your engine needs oil to lubric ... read more

Bad Vibes

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something. There are a few things that can cause your steering wheel to vibrate as you drive down the road.  One of the most common is out-of-balance tires.  You may not only feel that wobble in your steering wheel, you might also feel it in the tires.  Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds.  So what is tire balance anyway?  Well, you have a rubber tire that fits around a metal wheel.  It should have the same weight all the way around.  If it doesn't, it will start getting the shakes.  Ever load your washing machine so that all the clothes are at one side of that drum that spins?  When it hits the spin cycle, it can throw that washer against the wall.  Th ... read more

Out with the Old (Vehicle Parts that Wear Out)

Some drivers don't pay any attention to their vehicles until something breaks.  Others take them into their service repair facility for maintenance even before a problem develops.  Still, even if you fit into the second group, there are some parts on a vehicle that will simply wear out over time. Your vehicle has gaskets in several places.  They use a flexible material to seal the gaps between metal parts that fit together. After time, that material shrinks or gets brittle and fails.  Eventually, after time, you will have to get gaskets replaced. Same goes for belts.  Your engine has belts that help take the mechanical energy of the engine to drive other parts such as the generator and air conditioner.  Heat and age will eventually cause these belts to wear out or break, so you'll need new ones at some point. You'll also find yourself buying brake pads.  As much as you may try to go easy on them, brake pads work by wearing off a little bit of them eac ... read more

Taking the Heat (Heater Hose Maintenance/Repair)

If you have an internal combustion vehicle, you know it has a lot of hoses that carry various fluids.  And if you have a heater in your vehicle, you'll have heater hoses. A heater hose connects to and from the engine so some coolant can be circulated through a little radiator called a heater core.  In cold weather, that heater core acts as a heat exchanger to heat up your cabin. Even in the hot weather, the heater hoses can prove problematic.  That's because they may remain pressurized even though you're not running your heater.  Heater hoses are made out of tough materials since they must handle heat and pressure.  But even the durable rubber, plastic and metal they are made out of can crack or leak from years of use.  That means coolant can be sprayed out into the engine compartment or leak onto a driveway or garage floor.  You may be able to see a puddle of coolant under your vehicle or perhaps smell the odor of the coolant under the hood.  So ... read more
