Variable Coolant Pump

WARNING: This page is about a different variant/trim than selected.
NOTE: There is still a thermostat for conventional thermal transient operation.
G11699190

The variable coolant pump has a shroud mechanism which can be used to create zero flow in the engine coolant circuit to enable accelerated engine warm-up. The only control from the Powertrain Control module (PCM) is a signal when the engine is cold telling the pump to move the shroud to a 'no coolant flow' position. Once the engine is approaching running temperature, the PCM removes this signal, the shroud retracts and full coolant flow is resumed.
