Coolant pump

Reaching the optimal operating temperature of a combustion engine more quickly is one of the remaining levers for further reducing CO2 emissions in vehicles. Keeping the coolant flow at a standstill after cold-starting the engine supports an effective warm-up phase, as the coolant in the engine will not immediately dissipate any heat generated by the engine.

MAHLE has developed a hydraulically controlled coolant pump, a system that due to its simple and robust design has a low system weight and can be adapted to existing engine cooling circuits.
