I have been losing antifreeze out of my car, heat comes and goes.gauge is all over the place.
If you are losing coolant, and you don't see any under the vehicle or leaks anywhere. The only place it could be going is into the cylinders and out the exhaust. Pull the oil dipstick and see what the oil looks like.If it looks funky or anything but oil, you have a head gasket problem. Is the car running ok?
Runs great going down the road .but runs rough when stopped.
