getting hacked off with this now......fitted new thermostat with jiggle pin to aid venting + fitted bleed valve in heater pipe at matrix end. No different - still not opening the stat and cooling.
What's weird is I can bleed the system with the engine off and then start the engine from cold OK. If I then undo the bleed screw on the heater coolant feed there is no water flow from it.....so still air locked??
I'm thinking of bypassing the heater completely on a temp basis to prove that there isn;t another problem somewhere else.
B***dy cars!
