Check Engine Light and/or Engine Overheating on BMW Z3

The thermostat may fail resulting in engine overheating and/or illumination of the Check Engine Light. Replacement of the thermostat along with a complete inspection of the cooling system will be necessary to correct this concern.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

While driving yesterday check engine light came on and noticed temperature guage in the hot area- after 1/4 mile I found a spot to pull over and I shut down engine and opened the hood. Upon examination, overflow thank was full and noticed coolant on engine, engine felt hot but did not smell burnt, At 27,000 miles the thermostat housing and thermostat was replaced, it now appears the water pump failed. Car was towed and now at the repair shop.
