KOOL-GUARD Si-OAT -38
Free from nitrites, amines, phosphates, and borates.
Protects from engine corrosion, overheating and frost.
Effectively protects engines against corrosion and deposits in the cooling system with its vital parts, the coolant channels in the engine block and cylinder head, the radiator, the water pump and the heater core.
Unlike traditional coolants, KOOL-GUARD Si-OAT -38 has excellent hard water stability and very low inhibitor depletion rates.
Compatible with most other ethylene glycol-based coolants, but for optimum performance and durability, we recommend that before using KOOL-GUARD Si-OAT -38 in systems previously filled with traditional coolant, the cooling system is drained and flushed with clean water before filling with KOOL-GUARD Si-OAT -38 following the vehicle manufacturers instructions.
