Hi, I have a small problem that is really cheesing me orf!!
A few weeks ago a hose came off a tee joint for the cooling system/LPG. Water went everywhere and she overheated briefly. I managed to stop within yards and had the AA out. We refitted and then refilled but she airlocked up and the AA guy went through bleeding the system which seemed to cure things at the time. However she kept drawing air in and blowing coolant out of the expansion cap. As time has gone on we have done several things,
1 Sniff tested- negative
2 changed expansion cap- no difference
3 added Kalimex gasket sealer- no difference
4 disconnected the lpg coolant pipes- no difference
The car will idle all day with no problems but if I drive around at normal temp for a few miles then she throws coolant out of the cap again. However if I just drive a little until she is just reaches normal temp, say a couple of miles then stop, then no problems but I still have the lpg and heater disconnected. The top hose does get hard when warm but softens as its cooler.
Now is my problem still a poxy airlock? or is it pressurizing from the engine somehow but not showing up on a sniffer test? or could it be something else. Or will Irontite additive help?
I had already changed the thermostat, water pump and rad a few months ago as I had the thermostat pack up and the pump and rad were looking a tad worn and as I was going to france and italy it seemed a good idea rather than face a problem over there. So 3800 miles later the problem starts 60 miles from home!!!!
But hey thats what makes Rangie ownership so much ******g fun!!!!
So any ideas guys, oh its a 4.0 V8 P38 1998.
Thanks
