coolant flow not giving enough heat

LPG will not work "Correctly" at temps under 5 Degrees the "Ambient" Temp MUST be Around 5 Degrees for it to "Flow" Properly

That's interesting, nowt to do with Rangies, but the central heating boiler in my Gite is located in an unheated area under the floor and fed by 35Kg Propane cylinders located outside, it works fine even at minus 17C

The cylinder that is active gets areally good coating of frost though

Does that mean that the gas used in LPG vehicle systems is Butane rather than Propane?

No it is Propane Keith, the OP is (More than Likley) sufferin from a frozen Vapouriser ....as LPG is stored in Liquid form, to burn it you have to Convert it to a gaseous state ...

the fact that your LPG line enters your property means it will convert to its gaseous state (about 5 degrees C) ..in a car it would'nt (coz its outside obviously) to "Make it Change" they fit a Vapouriser connected to the Cooling system the hot water flows thru 1 side of the vapouriser & the LPG the other raising the temp of the LPG & "Converting" it into a gas

this is then injected into the engine & runs the car

as long as your car engine warms up then the lpg will work..as its not working, i suggest that your vaporiser or water lines to them are faulty/blocked/air lock etc...

if working properly the lpg will work to minus squilleions,it just needs the engine heat to make the vaporiser work..to turn the liquid propane into gas requires a fair bit of energy,so sytem has to be in good order when jolly cold outside..

top up the engine coolant and bleed any air off, your vapouriser probably has a bit of air in there!!!
