Thread: Water/ coolant system advice

Hi all , just picked up an 86 range rover with a 3.5 V8 that runs well , albeit with some bodge efforts under the bonnet im in the process of getting sorted .
When i got it , the resovoir cap had been bodged with a bit of rubber to help get a seal on it , which wasnt doing much of a job , so went out and bought another couple with different pressure ratings , and not sure what i actually need for it .
i put one on ( havent done any real driving in the car yet ) that has a rating stated on it for 15psi , is this suitable for it ? or is there another one i need to be looking at ?
The cap i put on did pressure the system because as soon as it did , i found a couple of hose leaks that i have since fixed .
Just not sure if this cap is the right one to do the job .
Also wondering what is the process to prime the system with water and get the air out .
Thanks for your help , im jumping in from an older more simple hilux , and all the electronic gear on this has me learning from scratch .
The motor has been converted from carbies to gas running an EFI , which is also needing some advice on , but that is another story for another thread !!!

cheers , James

Good stuff , thanks mate , when the system was under pressure with the new cap it showed a small pin jet leak out of the bottle on the top seam just near the filler cap , which will have to solder up today , then get into why the gas converter is freezing up , which i read about on here last night could be because of the heater unit turned off and im pretty sure the heater isnt by passed .
Hopefully with the bottle soldered and get the converter freezing sorted i might be able t get it on the road and give her a bit of a run , once i get all the little niggling problems sorted in the engine bay and learn a bit more about it .
cheers ; James
