Thermostat Test

WARNING: This page is about a different variant/trim than selected.

Check the electric thermostat for loose or corroded connector(s), check the operation of the electric flow/direction valve(s). If the engine still does not maintain the correct temperature, assume the fault is with the operation of the internal wax type thermostat. Check and replace parts as necessary
