4.0 over heating after 20 mins of driving

rodell · Sep 11, 2010

Hi guys ,
my range rover p38 4.0 is overheating after being driven for 20 -30 mins , not had any time to look at it yet , but wondering if this is a common thing or any common things to check

water pumps and leaking thermostats.
Liners and head Gaskets.
But try being less lazy and look first-your mother does not work here

the P38 V8's are well known for overheating and head gasket failures because of it, Check out your cooling system asap!!!!!

Fan or radiator also, Best get a garage to sniff test with Exhaust Gas Analyser over header tank- if HC jump = head gasket/liners.
Does the top radiator hose go rock hard?

hi guys , sorry for late reply , was working till 3 am , the top hose isnt getting hard , going to take fan belt off and make sure the water pump turns ok , and going to take thermostat out and see if that helps , if that fixes it il replace it

you can not run a v8 without a stat, are you sure you have not got a water leak. you wil need to take the water pump off to look at it propply..

mangle the inside of an old thermostat and try running with it,

Is it low on oil ? That may cause overheating
