Still no further on guys,wish i had never changed the fan switch over in an effort to find out should the fans come at a low speed and then high.
1st attempt,remove Vx switch,replace with euro parts switch,so old switch out ,new in,top with water,fire up,heater on high and full,warm air coming through in a few minutes,no boiling over,but fans dont kick in to 100+,worse than before and not staying on for half the time..
Day 2 same as above,but change back to original switch. EVEN WORSE !.. Cold air blasting through heater vents,boiling over.AIR LOCK for sure can shift it not a hope,fans working,not at all,Im I prepared to keep running my Pride and Joy up to these silly temps,FORGET IT !
Right now i would be happy to get that Dam Airlock shifted and the water ciculating properly even without the coolant. Ive checked the guides nothing on removing air locks as far as i can see.
Someone must of had this nightmare, because guys short of ripping out the thermostat I need someone to PLEASE point me in the right direction. :-/
2000 3ltr MV6 Face lift,any help would be much appreciated

Thanks John..
