Didnt think that our XJ fit in the TOTW catagorie soooooo..
'88 XJ
4.0
stoopid closed loop cooling system.
good head gasket,
good head,
new 3-core radiator,
new thermostat, (also tried with no thermostat)
Electric fan kicking on about 180
block/heater core flushed
new hoses
new shroud
new fan clutch
no exhaust gases in cooling system
new water pump.
We are at a total loss here guys.. WTF is wrong with it?
It will idle for about 15 minutes then just boil.
It will drive for about 10 minutes then just boil.
at first it seemed as thought the #1 piston was just cooking. If you poured some water on the #1 @ the head it would cool off FAST.
so we pulled the head, took it in, had it check out. good to go.
put it back on... now it seems that #3 is just fawkin cooking. same scenario, havent re-pulled the head yet.
I dont know..... this is really getting agrivating.
