PRECOOL RTU – Ready To Use Engine Coolant

PRECOOL

Powerex PRECOOL RTU is a ready-to-use engine coolant formulated for automotive and industrial cooling systems where pre-mixed coolant performance is required. The coolant is designed for direct filling without additional water dilution, helping avoid incorrect mixing ratios during service.

Built with THERMO CARE TECH, PRECOOL supports uniform cooling behaviour, reliable heat management and protection of radiator and cooling system components during regular engine operation. Its ready-mix formulation helps maintain coolant consistency in use and supports smooth circulation through cooling passages.

PRECOOL is suitable for vehicle owners, workshops, fleet users and maintenance teams looking for a dependable ready-to-use radiator coolant for routine coolant replacement, heat control and cooling system care.
