For best results, the cooling system’s Mixture pH level should be maintained between
8.0 and 10.5. Check your engine manual. Some engines may require slightly different
pH ranges.
CAUTION! Most Rocore radiators are made of steel, copper, brass and solder
materials. Some radiators may include aluminum materials. If you have an aluminum
radiator, special attention must be made in selecting a coolant that is compatible for use
with the aluminum materials.
See the engine manufacturer’s manual for more information on recommended coolants,
coolant additives and maintenance.
