METALGUARD® SCA81

METALGUARD SCA81 helps extend antifreeze-coolant life by providing an additional dose of inhibitors to protect all metals in the engine’s cooling systems. It includes components to help prevent scaling and fouling, and boosts additives that will control cylinder liner pitting, pump cavitation, and corrosion.

METALGUARD SCA81 increases the nitrite levels in your coolant by virtue of its high nitrite content. SCA81 can be used to convert coolant that meets the basic ASTM heavy-duty standard (ASTM D4985) to coolant meeting ASTM D6210, the fully-formulated, heavy-duty precharged coolant standard.
