Eliminates the need for SCAs and coolant filters, saving time and money. Also available in a 50/50 pre-diluted mixture.

PEAK Fleet Charge Coolant/Antifreeze is the original fully formulated Supplemental Coolant Additive (SCA) pre-charged antifreeze. The patented inhibitor package provides superior protection against cavitation erosion, corrosion and scale for all heavy duty cooling system applications. Also available in a 50/50 pre-diluted mixture.

PEAK Full Force Antifreeze meets the low silicate requirements for heavy duty engines. 5-Way protection: Freeze Up, Scale Build-Up, Boil Over, Sludge Clogging, and Rust Corrosion. Also available in a 50/50 pre-diluted mixture.

SIERRA Antifreeze/Coolant is formulated with PG rather than EG, the base for traditional antifreeze. Sierra Antifreeze is less toxic and therefore safer for people.
