Dorman Hybrid Coolant Control Valve

A hybrid or EV battery has to be held inside a narrow temperature band to charge fast and to last, so it carries its own cooling loop with its own pump, valves and heater. These parts fail far more often than anything in the drivetrain, and a pack allowed to run hot loses range permanently rather than temporarily.

Supplied by Dorman.
