Engine Cooling problem
2005 Chevy Colorado 4 cyl Two Wheel Drive Automatic 82000 miles
My colorado 2.8 4 cyl throwing code "operating temperature below thermostat threshold temperature" gauge was reading to cool for days "would not read above 1/4 hot" replaced coolant temp sensor now reading temperature correctly "just under half way on gauge" wondering if it could be thermostat stuck open "heat works" code is p0116 according to manual there are no other sensors in reference to engine temperature im stumped could just throw in another thermostat but dont want to waste 57 bucks if it isn't " you have to replace the whole housing it is 1 piece.
have the same problem?
