Engine coolant and fault diagnosis

THE latest MACS Service Report from VASA’s North American counterparts is all about OBD II diagnostics of engine coolant temperature sensors and thermostats.

In modern vehicles, problems in the engine cooling department can have a knock-on effect with numerous other systems, including locking out the air-conditioning system. Being proficient in diagnosing problems here can save hours of head-scratching.

VASA members can access the MACS reports from the members section of the VASA website.
