Overheating issues, guidance appreciated
Yesterday my z started overheating while driving down the highway, temp got to just under 3/4 on the gauge. I turned the heater on 90 degrees and full blast. The temp went done pretty quickly to 1/2 on the gauge.
When I got home I checked the coolant reservoir and fluid level was just below the min mark. I opened up the radiator cap and bleeder and slowly filled via the radiator.
Let the motor heat up and then shut her down to cool off.
Took it for a drive this morning the radiator fan kicks on as soon as i start it up and it started overheating around 10 min of city driving.
Got game and tried to purge via the bleeder and funnel method (using regular funnel held in tightly)
The funnel filled with coolant once the engine heated up but no bubbles came out of the radiator. There were lots of tiny bubbles like foam coming out of the bleeder. Let it run like this for about 10 min until so much coolant was coming out of the bleeder that it was spilling all over and evaporating into coolant smoke.
Does this sound like air in the system, thermostat, or head gasket?
Thanks

Thanks. I was thinking the same thing. I had been missinformed by someone saying that the heat wouldn't work if the thermostat was stuck closed.
