Bleeding Airlock

[banditman]

Hells Bells I am having a right old battle with air in my cooling system...how the hell do you bleed it???

I think my heater isn't helping because that is not performing very well, and the engine is overheating.....lorra air in there because it gets hot, blows all the water out and theres nowt left.....

Or could it be stuck 'stat ??

Heeeeeelllllppppp !!!!?????

There's a nice system my mate uses at his garage, they suck all as much air out of an empty system as they can to check for leaks, then insert a pipe into a drum of pre mixed coolant and it sucks it back into the system, fantastic piece of kit, only needed to top up the header tank the next day.

Firstly you should fill the EFi through the small brass plug on the heater circuit, not through the header tank.  I occasionally bleed mine out here and also at the top of the rad.  System needs to be under a little pressure though.  I'd also try some radflush.

:( from your discription sounds like a head gasket if its blowing the water out
top up the system run the engine with the rad cap off and if it bubbles continuly then you need to get a co test done at a garage
(CO TEST IS A FLUID THAT CHANGES COLOUR WITH EXHAUST GAS)
yery acurate way of testing for blown head gaskets

The blowing water out sounds exactly like RRR when it split a hose and overheated, there's air in there and the wtaer is boiling 'till it's superheated, that's why it 'explodes'.  Bin the 'stat if you are unsure.
