I've spent £1800 in parts to give my rangie an overhaul, I was happy with the running of it, been on on the road 2 month and covered around 1000 miles so I was happy it was good to go for LPG conversion so booked it in. £2136 later I picked it up last night and got home, only a short journey and on turning off I get the dreaded coolant level low. Gets out to steam coming out the bonnet. Thought it must be down to Lpg conversion as I've fitted new rad, water pump inc new O Rings, low temp stat, oil cooler and pipes inc stat and new pipe from water pump to oil cooler.

I called LPG guy this morning and he drove to my house to have a look, we discovered water out from the water pump area. He didn't touch that area so any ideas what it could be? 2004 RR 4.4 V8 Autobiography

A failed water pump?

And the LPG conversion wont have caused this to fail, it might just be bad timing. Current:

I fitted a brand new behr hella genuine water pump only 1000 miles ago. 2004 RR 4.4 V8 Autobiography

LPG kits do cut into your water supply, this being a pain BMW heater system they have to be connected correctly other wise it can't flow the water correctly

if the water is coming from the same side as the LPG regulator is fitted have a good look a tall the hose's there and where it connects to original hose's

A picture would be useful, to see where he's fitted the regulator. It should be below the header tank or it will never bleed.

Turned out to be the water pump gasket. It has slightly dislodged on fitting, just suprised it waited till now to let go. 2004 RR 4.4 V8 Autobiography

A little off topic; I see you are in Warwickshire, same as me, who did you use for the lpg conversion? One of my other cars uses lpg and I have been looking for somewhere to get it serviced.
