Firstly Hello guys and girls.

My names Dean, Im actually a Toyota mr2 owner but have came here for some advise on my friends fiesta.

earlier this week 2 spark plugs wouldnt remove from the head so had to get them drilled out. so removed the head and got that done. put it all back together with new head gasket, manifold gaskets etc etc.

now there is air in the system and i cant find a bleed vlave to remove the air,

Can anyone help?

many thanks

A bit more info may help us to help you help your friend.... Is the engine OHV or CVH? Also, what makes you think you have air in the system? Air locks are a rare thing on cooling systems with an expansion tank as they are designed to allow any trapped air to automatically bleed into the exptn tank. To depressurize system remove and re-fit filler cap on exptn tank or radiator. If you're experiencing little or no coolant flow, over heating or cold air from heaters then it could easily be something else.

cheers for the reply, its a OHV engine.

when i start the car its rev's really high and doesnt drop down even once warm. If i blip the throttle the rev's return to idle for a matter of seconds and then go up again, then about once every 30 seconds the revs jump up and down as if there is air going past the temperature sensor (thats why i thought trapped air). oh I changed the thermostat si that works fine, and is the same temperature reading as the old one.

anyone got any idea why the revs are so high? and why its jumping then? I've gone over everything and there arent any sensor that i didnt plug back in or anything.

Do you get idle control valves on the mk3?
