Antifreeze

Antifreeze, or coolant, helps to keep your engine at the proper temperature and prevent corrosion. Antifreeze has a higher boiling point and lower freeze point than water. This keeps the engine from overheating and prevents fluid inside the engine from freezing in the cold. When liquid freezes inside an engine, it expands and could crack parts of the engine. Checking your antifreeze regularly can help you avoid problems on the road. When you're low on antifreeze, you may notice your vehicle overheating and your heater may stop working. Running the vehicle longer can blow the head gasket, warp the cylinder head, or damage the engine block. Make sure and check the antifreeze level every time you open the hood. O'Reilly Auto Parts stores carry premixed and concentrated antifreeze options to best suit your vehicle.
