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.
