JA: Anything else you want the mechanic to know before I connect you?
Customer: no thats it

Hi Im David. absolutely add coolant to the full level in both the radiator and reservoir. see if that takes care of the issue, if not the engine coolant temp sensor should be replace. do you have a check engine light?
