A Fluid Situation (Check Fluid Levels)

There's one fluid in your car you are always careful to keep at a certain level: the fuel. If you don't have fuel, you're not going anywhere.  Your vehicle has other fluids which are vitally important to proper and safe operation, too.  So, here's a "level" headed approach to those "other" fluids. Engine oil.  This one's probably the most important fluid to maintain at the proper level. Without enough oil, you'll wear out your engine prematurely.  Sometimes vehicles have warning lights on the dash that will tell you to get your oil checked.  Don't ignore that one; get it checked immediately.  Certainly don't go on a long trip at high speeds with your oil level low. Oh, and it's not good to have too much oil in, either. Our pros at John's Automotive Care can advise you on oil levels and tell if you if you should be concerned about abnormal fluctuations.

Steering You Right (Power Steering Signs of Problems)

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the "good old days."  Today, we take our steering for granted: until something goes wrong, that is. Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches.  Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid. Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for: A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn. Signs of hydraulic fluid leaking, such as wet spots under your vehicle. The smell ... read more

A Sticky Brake Situation (Parking Brake Service and Maintenance)

We've all been there.  You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands.  So you decide you'll use the parking brake.  When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on.  It's stuck.  What do you do now? Welcome to the world of infrequently-used parking brakes.  Yes, they do stick for several reasons. It's common for components to corrode and get locked up.  Sometimes if you have applied it extra hard, it can jam.  Could be a rusty cable, could be a spring that doesn't return the brake to its disengaged position.  Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick. There are a few things you can try to unstick it.  Carefully rock your vehicle by putting it first in drive and then reverse.  You ... read more

A Head Start on Starting (Battery Testing)

If your vehicle isn't starting or doesn't sound like it used to when you crank it, the culprit may be the battery.  You may have left a light on, or something plugged into one of charging ports.  Maybe you accidentally left your vehicle in the "on" or "accessory" position when you last got out. Maybe you've left it in the garage or driveway for a long time without starting it.  That can spell the end for a vehicle battery. It's also possible that your battery is just simply too old. There's no standard lifespan of a battery, but 3-5 years is about average, even though some people only get 2 and heavier duty batteries may last many more. It's possible your battery is defective, too.  And it could be your vehicle's charging system isn't recharging the battery.  Whatever the cause, if you're having problems with your battery, it's a good idea to bring it in and have us perform a thorough battery test.  With state-of-the-art testing equipment, a technician wil ... read more

Emergency! (Vehicle Emergency items)

"I never expected it could happen to me." Countless drivers have said that after they've had an emergency turn their lives upside down. So before that happens to you, let's thinking about planning ahead for an emergency with a few things you should keep in your vehicle. Road flares. If you've ever driven by a disabled vehicle sitting at the side of the highway at night, you know how terribly hard it is to see, especially in bad weather like rain.  If you are the one in that broken down vehicle, you run the risk of being hit by a vehicle whose driver literally may not be able to see you.  The best emergency signal includes one or more road flares.  There's a reason police officers and firefighters carry them in their vehicles.  When you see a series of burning red flares at the side of the road, you know something serious is going on.  These are far more visible at a much longer distance than nearly any other portable signal device.   Fire extinguisher ... read more

To Fix or Not To Fix: That Is the Question.

No matter what vehicle you drive, when certain things break, you have to make a decision.  Should I get it fixed now, later or never?  Air conditioning is one of those things.  You can certainly live without air conditioning, but it sure is nice to have on a sweltering day. Let's say your air conditioning breaks in the fall and you live in a climate where it gets quite cold in the winter.  Should you get it fixed now, wait until spring since it won't get warm until then or maybe not get it fixed at all? That can be a tough decision.  There are several reasons air conditioning in vehicles break.  One is fairly simple: It could be an electrical problem, perhaps a relay or solenoid is not turning on the system.  It's also a fairly inexpensive repair and doesn't require hours of labor. Or, the problem is that the coolant has leaked out.  Your service facility can find the leak and replace the parts that are leaking.  With a refrigerant recharge ... read more

The Flat Fix that Fits (Tire Repairs)

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

A Hot Mess (AC System-Compresser)

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most.  Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails.  It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon).  That makes it hotter, so it then goes through a condenser that cools it off.  Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator.  That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day. Of all these parts, one that does a lot of work is the compressor.  It has to compress that refrigerant and circulate it through the system.  It turns on and off several t ... read more

When Your Air Bag Light Comes On (Illuminated Air Bag Light)

There are some dashboard lights you should pay more attention to than others.  One is the air bag light.  If it's on and your vehicle is in an accident, your air bags probably won't do their job. Automakers began installing air bags in the late 1990's since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt in combination with an air bag gives passengers the best chance of surviving a crash and minimizing serious injury. The air bag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated air bag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off." Different things cause the air bag light to come on.  Your vehicle may have been in an accident during which, while the air bags didn't inflate, crash s ... read more

Round and Round (Wheel Balancing)

In a perfect world, all wheels and tires would be perfectly round and weigh exactly the same at every point of the wheel.  Unfortunately, they're not, and if they're out of balance, they can reduce the lifespan of your tires, make your vehicle shake like a carnival ride, and maybe even damage a few suspension parts along the way.  You don't want that! Wheel balancing, sometimes known as tire balancing, is a process by which a technician makes sure your tire/wheel assembly has evenly distributed weight.  If it isn't, it can give your ride bad vibrations.  If you feel your vehicle's steering wheel shaking, it can mean unbalanced wheels in the front. If you can feel a vibration in your seats, it could be unbalanced rear wheels. In addition to your vehicle vibrating at higher speeds, there are other signs that your wheels are out of balance. You may see uneven tread wear, or you may notice you aren't getting the kind of fuel economy you used to.  When you experienc ... read more
