Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.
Have you had this scanned for codes?
Take it to any auto parts store and ask for a free scan. If the coolant temp sensor is the problem it will usually set a code.
The coolant temp sensor is threated into the side of the cylinder head.
