MOTUL HD COOL INTER ULTRA

HD COOL INTER ULTRA is an anti-corrosion coolant concentrate that builds a protective layer on the inside surfaces of the cooling system particularly those already being affected by corrosion (engine blocks, cylinder heads, liners, water pumps and radiators). The organic acids will seal the surfaces affected and prevent further corrosion taking place.

HD COOL INTER ULTRA uses hybrid organic acid technology (HOAT) for improved corrosion protection.

Also available as a 50:50 mix called HD COOL INTER.
