Ask Joe Mechanic: Vehicle Winter Readiness


The seasons are changing so it is time to start thinking about getting your vehicle ready for winter. There are a 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 of 12,000 miles per year, you need to have your car serviced at least twice a year.  Spring and fall are an excellent time 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. We covered a lot about tires last week, but, while your car is on the lift, your technician can give them a good professional check over, and if necessary, do a tire rotation for you.  If he does a tire rotation, while he has each wheel off, he can do a quick visual brake check to make sure your pads do not need replaced.

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 this area, that should be at least -35 degrees, because you never know while traveling, you could run into a cold pocket of air in some valley.

One Monday morning three years ago, when I left my house to head north, it was - 5. As I headed up I-81, I watched the temp display on my car start to drop and by the time I passed Hazleton, it was -15. It stayed about that temp all the way until I exited I-81 about 30 miles north of Scranton to head for a small town called Hop Bottom. As I descended into the valley, I watched the temperature display start to fall, first -18, then -20, a little later -22, and finally bottoming out at -25 degrees. So, you just never know when you may need that extra protection.

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

Also, check 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, check for cracks or if they are bulging or have a spongy feeling near where they connect to the radiator or engine.

Checking the condition of your battery is very important. Do a visual check for corrosion around the battery posts and
cables. If present, corrosion needs to be thoroughly cleaned off, being 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.

Other items you would want to check if your vehicle is equipped with them would be your heated seats. You also need to check and make sure your front and rear defrosters and your heater are working properly.  If you check these items, your car should be pretty well prepared for winter, but remember, problems can arise quickly, and without warning, so, if your car suddenly starts acting differently, get it checked, it may be nothing, but it is much better than sitting beside the road.

Recent recalls:
134,100 2008-2010 BMW 528,
535, 550 & M5 models
For a rear light grounding problem which could cause failure of one or more rear light functions.

If you think your vehicle may be affected by this recall, contact you dealer or manufacturer for further information.
