    As I said before, you can use the aircon fans for cooling.

    Head should NOT be skimmed.

    Have you tried running it without the stat in? Cannot remember if you'd said you'd replaced it or not. Britpart are a fiver so worth a shot as a test before you give up.

    I read that it..it should not be skimmed in rave ..but why do all eBay recon ones and mechs say it...if it has to be done ...are the tolerences and stresses to much then for the cylinder head once it's warped to be skimmed

    The head is already weak, a skim just ensures it will fail. Head gasket failure is less common than a cracked head but if it was OK until you stopped it does not sound like a cracked head to me. If the expansion tank is not holding pressure or the cap is NBG it will boil.

    Ok that took some time to establish. Next thing is remove stat and run without it for a time, check that it is opening properly out of the car. If it is you maybe looking at cracked head. Best advise is NEVER fit a cheap stat. If the head isn't cracked it soon will be if you continue as is.

    Unlikely to be stat then, but you never know. It's starting to sound a bit ominous. Do you know anyone with a static test rig?

    Look at Landyzone international rescue map see if there is anyone close with the tooling to test the system.

    Hi my p38 dse dose the same i changed pump thermostat and rad after driving 40 odd miles it was ok, on way home hot again found air lock in rad and small amount of water coming out of over flow so i fitted a new bottem seal on rad cap seems ok at moment , i think the water loss gives a air lock and stops wate going round engine
