i have a 4 litre v8 range rover petrol with lpg conversion it temperature was always ok untill driving down motorway the red light came on pulled over let it cool down got to garage top up water and it had loads of bubbles coming out of it it seems to be over pressurising and heater is blowing cold its also got quite alot of smoke from exhaust
or its got Rabies!
and the bubbles are? and what about the smoke and over pressure?
heater blowing cold is rarely 'simply not enough water'
