Hello.

Started off after sitting all night engine would run rough for acouple of minutes then run smooth, then after a while started to lose coolant but I couldn't find the leak, now engine temp whent up to to the red pulled off the road and sit for a couple of minutes and restarted and temp went down to normal temp..
I have replaced thermostat but when I run the car it still gets hot and top raditor hose is cool like thermostat mot opening I can open the bleeder valve and air bleedes out and then thermostat will open.
I am not getting any coolant in oil or smoke out tailpipe.
I am afraid I know what is wrong but I am joping there could be something else.

Intake or headgasket. Is the oil clean (no water)?
