Radiator Care

Radiator care products that help keep your car's cooling system clean and sealed. Use them for periodic cooling system maintenance or after repairs that left oil residue or deposits behind.

Radiator Cleaner has an acid-free formula that helps remove oil, scale, rust and sludge from the radiator and cooling system without damaging aluminum or rubber parts. Radiator Leak Stop helps seal small cracks and leaks that cause coolant loss, works with water and antifreeze-based coolants and can also be used in interior heating systems.
