Antifreeze / Coolant
Heavy Duty Antifreeze
High Performance Conventional Antifreeze / Coolant
Crystal Clean Heavy Duty Conventional antifreeze/coolant is fully formulated and ready to add to your vehicle’s cooling system with no further dilution necessary. It is formulated with a heavy-duty additive package that contains the initial charge of supplemental coolant additive (SCA) and a minimum of 1200 ppm Nitrite (as NO2). It provides excellent protection from cavitation erosion/corrosion in water pumps and wet sleeve cylinder liners, as well as excellent overall corrosion protection for multi-metal systems.
This antifreeze/coolant includes ingredients to disperse minor oil leakage, prevent fouling, control hot surface scaling and it will not damage vehicle finishes or rubber parts. In systems where coolant filtration is in place along with a formal monitoring and maintenance program the coolant can provide up to 3 years/300,000 miles with the addition of heavy-duty supplemental coolant additive as needed. Monitoring and maintenance of the engine coolant should include regular testing at normal oil drain intervals.
