Heavy Duty 2-in-1 Coolant Treatment

LUBEGARD provides aluminum protection with newer proprietary organic technology, unlike some competitors that use outdated molybdate and phosphate for pH buffering — an ingredient that Detroit Diesel does NOT permit for use in their systems. LUBEGARD contains no phosphate, and receives across-the-board OEM acceptance.

LUBEGARD contains wetting agent ingredients, which provide engine temperature reduction performance — eliminating the need and expense of using an additional product like Red Line® Diesel Water Wetter. Testing has shown that the polysiloxane in Water Wetter polymerizes to form a nasty layer of slime within the radiator. LUBEGARD does NOT contain any polysiloxane ingredients.

For DECADES, PenCool and Fleetguard formulas have been the “gold standards” against which all others were compared. With the introduction of LUBEGARD 2-in-1 Heavy Duty Coolant Treatment, this is about to change.
