Q: Car has oil in coolant

asked by on

My car is running hot. It looks like I have oil inside of the coolant reservoir.

Hi there. Oil inside the coolant reservoir can mean you either have a cracked head, A blown head gasket, or a warped head, or all of the above. To be safe, I would not even recommend fixing the head. I would get a new motor to avoid further problems. The damage is already done.
