during the cold winter months is a simple and inexpensive way to make sure your car won’t leave you stranded. Antifreeze is vital because it is used to cool the car's engine, protecting it from freezing in cold weather, and providing heat inside the car to keep you warm and toasty.Maintaining your vehicle’s cooling system takes just a few minutes, and is well worth it when you consider that you could be stranded in the cold with an overheated engine. Cooling system failure is the leading cause of engine related breakdowns, which can cost thousands of dollars and leave you and your family stuck at the worst possible time.
Keeping the engine operating within the correct temperature range is the cooling system's job, protecting your engine against damage. More than 27 percent of vehicles checked during National Car Care Month had low levels of coolant while 20 percent needed a coolant flush, which is needed to protect the system from rust, dirt and mineral deposits.
When checking the level of antifreeze/coolant in your vehicle, you will need a few basic tools and an antifreeze ball tester. Make sure the engine and coolant system are cool before you begin. Never open a hot radiator or coolant reservoir/overflow tank as it can cause severe burns. If the antifreeze/coolant is low, add a 50/50 mix of antifreeze and water. If changed recently, but your antifreeze level is low, use the antifreeze ball tester to make sure the anti-freeze-to-water ratio is correct.
This is also a good time to check for and replace any leaking, brittle, spongy or cracked hoses and to make sure that the radiator hose clamps are tight to prevent leaks at the connections.
The following tasks should be performed by a do-it-yourselfer or professional auto technician to help insure car is ready for winter driving:
- Change oil every 3,000-5,000 miles, depending on what your vehicle manufacturer calls for in the owner's manual; consider changing to a "winter weight" oil if you live in a cold climate. For less wear and tear on the engine, drivers in sub-zero driving temperatures should drop their oil weight from 10-W30 to 5-W30.
- Check the battery for signs of corrosion. Before driving long distances, it is a good idea to have the battery life tested by a professional service technician.
Make certain the heater/defroster is working properly and keep the gas tank full to minimize the risk of gas line freezing from condensation built up. - Check tire tread depth and tire pressure; consider snow tires if snow and ice are a problem in your area.
- Check to see that lights work and headlights are properly aimed.
- Replace wiper blades every six months; consider winter blades to keep snow and ice out of the working joints of the blade that prohibit it from fully connecting with your windshield.

Some would say the auto maker's move to 100,000 mile "tune-up" intervals on many new vehicles will finally kill the tune-up as we know it today. Maybe, but what the car makers are really talking about is 100,000 mile spark plug change intervals -- which does not include the need for other tune up type maintenance such as oil and filter changes or other repairs that might be needed during the life of the vehicle.
