Q: Car runs hots after oil change

asked by on

After getting an oil change, my car is running hot.

More than likely, these issues have nothing in common. While engine oil does help to both cool and lubricate, the first sign of an oil system problem would not be overheating. The only way I can imagine a possible correlation is if the technician changing your oil left the radiator cap off, which could cause overheating. Most repair facilities offer a courtesy check of all the fluids during an oil change, including the coolant. I would not drive your vehicle until your issue is resolved, as overheating can lead to extensive engine damage. I suggest you have a trained professional run a diagnostic inspection of your overheating issue. YourMechanic is an excellent option since we make house calls.
