KOOL-GUARD MPG-HD 50:50 is a propylene glycol, low toxicity, ready-to-use refrigerant coolant for petrol and diesel engines. The inhibitors used in C3250 include organic acids in combination with borate, silicate and nitrite. These inhibitors are known to provide excellent protection in heavy-duty applications, particularly where there is potential for cavitation erosion-corrosion to occur.
KOOL-GUARD MPG-HD 50:50 provides freeze protection down to -34°C.

Product Code: 11680

Much lower toxicity than monoethylene glycol-based coolants
Thermal characteristics that permit effective engine cooling without boiling
Elimination of deposit problems caused by the use of hard water
Improved anti-corrosion protection of all metals and alloys used in the cooling system of modern vehicles, especially the aluminium
Protection against frost, depending upon the concentration chosen
Excellent antifoaming characteristics
Exceeds the requirements of ASTM D6210
Meets most European and International Standards
Provides total protection from -34˜C to normal operating temperatures

KOOL-GUARD MPG-HD 50:50 is compatible with most other ethylene glycol and propylene glycol-based coolants, but for optimum performance and durability, we recommend that before using KOOL-GUARD MPG-HD 50:50 in systems previously filled with traditional coolants the cooling system is drained and flushed with clean water.
