Ask Joe Mechanic - Getting Ready for Winter

The seasons are changing so it is time to start thinking about getting your vehicle ready for winter. There area number of things that sometimes get overlooked which are very important and can be very expensive to repair.  This is a good time of the year to have your car serviced. If you drive an average number of miles per year, about 12,000 or less, you need to have your car serviced at least twice a year.  Fall and Spring are excellent times to do this as it allows you to prep your car for winter’s cold and summer’s heat respectively. If you are not a “do-it-yourselfer,” and take your car to a reputable shop, they will most likely already be checking these things for you, but it never hurts to make sure.

            In addition to the normal oil and filter change, it is very important to check your tires. Check your tire pressure first of all. You should always inflate your tires to the vehicle manufacturer’s recommendations for your type of usage. Most vehicles have a label either on the driver’s door or doorjamb, if not, the information is in the owners’ manual. Do not just go by the maximum pressure marked on the tire sidewall, as this may not be suitable for your vehicle. A tire that is a few pounds low on air pressure can cost you 2 to 3 mpg.  At $3.50 per gallon, nobody wants to waste gasoline!

            When you are checking your air pressure, look for signs of abnormal tire wear. A tire that is worn on just the inside or outside edge is usually a sign of an alignment problem. If the tires are worn on both the inside and outside edges, this is usually a sign they have been run underinflated. If the center of the tire is worn down with good tread on the edges, this is a sign of either the tires being overinflated or having tires that are too wide for the wheels on the vehicle. This is seen most commonly on 4WDs.

            While your car is on the lift having its oil changed, your technician can give your tires a good professional lookover, and if necessary, do a tire rotation for you.  If he does a tire rotation, while each wheel is off, he can do a visual brake check to make sure your pads do not need replacement.

            When you get under the hood, there are quite a number of things that should be checked. Always check your antifreeze for fill level and condition. If your antifreeze is discolored, especially if it is rusty colored, you should have the system drained and flushed and refilled with new antifreeze. If you are not having the coolant changed, you should have it tested to make sure the level of protection is sufficient for your area. For our region, that should be at least -35 (F) degrees, because you never know when in your travels you could run into a cold pocket of air in a valley.

            Another item often overlooked until the first good freeze is your windshield washer solvent. Because people often add water over the summer, when the weather turns cold, I have seen many washer reservoirs frozen solid. It is important in the fall and winter to add full strength washer solvent to give maximum protection.  If the reservoir freezes and cracks, it can be expensive to replace because in most new vehicles it is not in a very easily accessible location and so may involve some significant labor to replace it.

Also, examine your belts and hoses. Check belts for proper tension and also for visible cracks. If your belts are older than 5 or 6 years old, it is a good idea to get them replaced.  It is not fun to get stuck on the side of the road with a broken belt on some cold morning.  As far as hoses, look for cracks or if they are bulging or have a spongy feeling near where they connect to the radiator or engine, if so, they should be replaced.

It’s also extremely important to know the status of your vehicle’s battery.  Make sure it doesn’t appear corrosive around the battery posts and cables.  If present, corrosion needs to be thoroughly cleaned off.  While cleaning, be careful not to get it on your skin, clothes or in your eyes. If your battery is not a sealed unit, the electrolyte level should be checked and add distilled water to bring it to the proper level if needed.

A few other items you may want to verify for proper operating condition are front and rear defrosters, your vehicle’s heater and if it has heated seats, making sure they’re in good working order.  If you check these items, your automobile should be pretty well prepared for winter.  However, do remember that problems can arise quickly, and without warning, so, if your vehicle suddenly starts acting differently, get it to the shop!  It may be nothing, but it is much better to be safe than sorry and sitting alongside the road in a disabled vehicle.
