waterworks problem

[MA70-3.0GT]

Yes, removing the "jiggle pin" from the thermostat has been known to help with burping, but if you don't want to do this then just ensuring it was fitted uppermost in the first place is worthwhile, as it's purpose is to allow air locks to pass the closed 'stat (not as a "bypass" for coolant to flow as some people think)

I had no trouble burping mine once the head gasket was replaced & the cracked heater matrix done away with but it was a pig before that unsurprisingly. What you could try though if you do have trouble is to push a close fitting piece of rubber hose into the filler hole and add coolant through that with a funnel attached high up to the bonnet/hood & then loosen the top heater hose and let the air come out from there. (That worked for me when I was faffing around hoping the HG wasn't duff when I first got mine, until I ran the engine again & pumped more air in!)
