So I was just under the hood of my car and this has been a recurring problem I put oil in yesterday it's a half quart low and it feels like a frying pan under my hood there's coolant residue everywhere but my temp gauge hasn't moved an inch I'll come out after not driving for 2 hrs and it's still at half way my account runs perfect so does the heat but I never hear the outside fans on is there someplace I can check to see if there's a problem or should I just take it to a mechanic
