Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** your check engine light on? Have any parts been replaced? Thanks.
Based on description and fact check engine light is on it sounds like problem is either thermostat or coolant temp sensor, most likely thermostat. You can have diagnostic code checked at your local parts store for free, if you are getting P0128 then replace thermostat. Let me know how it goes or if you have more questions, thanks.
