Specially formulated to meet the stringent aluminum corrosion protection requirements of todays automotive engines, Shellzone Antifreeze and Engine Coolant is a low silicate, all-purpose coolant designed for use in both automotive and heavy duty diesel engines (with the use of supplemental coolant additives; SCAs). Because of its low concentration of silicate, Shellzone Antifreeze/Coolant complies with Cummins and other heavy-duty diesel engine manufacturers silicate requirements. It is also suitable for use in industrial internal combustion engines where an antifreeze/coolant is required to provide protection against freezing, boil over, and corrosion. This Pre-Diluted version is a 50/50 volume mixture of Shellzone Antifreeze/Coolant with deionized water, and it is ready to use and requires no mixing for top-up and initial fill.
