Antifreeze: this is many people’s first thought when it comes to winter car care. "Flush and fill" promotional signs abound at service stations as the weather cools.
But chances are good your engine coolant (a better name for it) is just fine for the winter ahead. If you've followed your car's service schedule regularly, give this pitch a pass. Most newer cars have been fitted with coolants that can last as long as five years or 150,000 miles. Read your owner's manual.
If you’ve missed a service interval or have another reason to doubt your coolant, go ahead and have it "flushed and filled." Just make sure your mechanic uses a compatible coolant to refill your car. Some coolants, such as Prestone's Extended Life, work for any car.
If your car has moved to a much colder climate and you’re concerned that your coolant might not be up to the deep freeze, you can check its effectiveness with a simple, under-$10 tester from the car-parts store.
