Overheating

Good afternoon.

When it overheated, did you turn it off and wait until it cooled down?

Does it continue to overheat and/or smoke out the tail pipe?

The no heat issue may be from either air in the system, low coolant or a failed head gasket from the overheating.

The smell with the AC on may be from a leaking heater core. Coolant may be in the case and the AC is blowing coolant as well as cold air.

Okay, thanks. At this point I would not drive it at all. You may have damaged the head gaskets already from the constant overheating.

In order to determine if they are bad, a test called a leak down test needs to be performed where air is added to the cylinders one at a time and watch for coolant movement out of the radiator at the cap.

That will confirm head gasket failure.
