Mystery Car problems continues... blows cold air and car overheats

Asked by Feb 28, 2017 at 02:41 PM about the 2002 Honda Civic EX

Question type: Maintenance & Repair

My car started to overheat and the car blows out cold air instead of hot and
does not bring the temp of the car down. Had it pressure tested and there
was no issues. Mechanic checked the heater core and it was fine. No milky
oil, no smoke or windows that fog up. Have replaced the Radiator a few
months ago and thermostat and was running fine. Car also leaks oil but also
cant figure out from where. Replaced the valve cover gasket. One mechanic
told me it was the head gasket... took it to another guy and he tested it and it
was fine. Car loses coolant but only while driving.

I would check the coolant level and purge the air out of the system. If you have a tiny leak that you cannot find try Alumaseal in the radiator.

It is not the radiator. I already checked it. I did get the air out too.

The lack of heat indicates a circulation problem. Air pockets can cause problems but a bad water pump is also a possibility.

There is no noises coming from the pump and no steam coming from the radiator.
