How to Maintain your Car's Cooling System
How to Maintain
Check your car owner's manual to see the recommended interval for changing your antifreeze and flushing your coolant system. New antifreeze will help your car's engine run cooler, and flushing it will remove any dirt, rust or sediment which may damage the water pump and clog your engine water jacket and radiator.
If you're a do-it-yourselfer, be sure to always follow the instructions for maintenance listed in your owner's manual. Dispose of used antifreeze according to your local laws and regulations. Use a closed container to store it, and never let used antifreeze drain onto the ground or into storm drains.
Consider using a flush solution which can remove much more sediment and rust than normal water alone. Ask your local Pep Boys sales associate to help you find the best flush solution and antifreeze for your car.
