Radiator Flush

BARCODE NUMBER: 9313555653326

Cooling system failure and overheating of the engine is the leading cause of mechanical breakdowns. Rust, grease, sludge and scale build-up all contribute to the likelihood of cooling system failure.

By not using a flush damaging debris remain in the cooling system, slowly deteriorating internal components and seriously impairing the proper function of the radiator & cooling system.

Wynn's Radiator Flush safely removes rust, grease and scale from the entire cooling system ensuring the new coolant works at its maximum potential, not having to work against a dirty system that can shorten coolant life. Wynn's Radiator Flush contains no harsh acid or alkali compounds and will not attack cooling system components.
