XJ Overheating advice

[undecided]

is it only boiling when you stop. Or does it also do it on the move. Dont forget to check the radiator cap if it does not hold pressure nothing else will matter

I upgraded to a 3 core radiator, hi flow water pump and bored out the thermo housing as on gojeeps site here :

and it's all good now!!

If its overheating at low speeds, but fine at high speeds, it suggests the fans.

If its overheating at high and low speeds its most likely lack of water flow for one reason or another. Bad water pump or blocked radiator
