Perform Radiator Maintenance
The radiator and cooling system in a vehicle require regular maintenance to efficiently reduce engine heat. Radiator flush or cleaner works by eliminating corrosion and debris that can impede the flow of coolant through the system. AutoZone makes it easy to compare the best radiator additives and flushes for cars and trucks from brands such as Bar's Leaks, BlueDevil, Prestone and Royal Purple.

Maintaining the cooling system in a vehicle can help to ensure that the engine runs efficiently at a safe operating temperature. Freezes or overheating can both cause significant damage to critical components. As coolant becomes more contaminated, the cooling system may not be able to maintain safe engine operating temperatures. Any type of debris in a cooling system can cause build up and blockages to form that limit the effectiveness of the cooling system. A low concentration of coolant may also lead to corrosion. Leaks can be another common radiator and cooling system issue.

Fix Coolant Leaks
If the cooling system or radiator in your vehicle has begun to leak, a stop leak treatment may be able to seal the leaks and prevent the engine from overheating. It is important to stop leaks as soon as possible. Search for radiator additives and flushes near me to see formulas in stock at the closest AutoZone store location.

Specialized stop leak formulas or sealers are available for every part of the cooling system from hoses to the head gasket and radiator. Some stop leak treatments combine metals such as liquid aluminum or copper with coolant. One metal or the other may be better suited for use with a vehicle make. Find out whether the additive you plan to use is safe for the cooling system in your car or truck.

Improve Heat Transfer
Additives can increase the effectiveness of a cooling system by reducing the surface tension of coolant. Some solutions may result in an engine operating temperature that is up to 20 degrees Fahrenheit lower than with standard coolant. Many additives also reduce the likelihood that corrosion or other deposits may develop and inhibit the flow of coolant throughout the system.

Save on Radiator Supplies
Compare additive applications and features to determine which formula is right for the cooling system in your car or truck. These solutions are most effective in a clean radiator and cooling system. In general, you should perform a coolant flush every 30,000 to 40,000 miles or at the frequency recommended in a vehicle owner's manual.
