The cooling systems of modern liquid-cooled engines put highest demands to the quality of the radiator coolants. 

Original HEPU® coolant additives are highly effective antifreeze. 

They protect the engine also from corrosion, overheating and formation of scale and thus offer an excellent heat flow for a perfect cooling performance.

All HEPU® premium coolant additives meet the requirements of the automotive industry and are an excellent addition to HEPU® water pumps and water pump kits!
