hi there everyone just wondered if any one can shed light on my problem changed the rad water pump and thermostat on my 4.0 p38 runs fine until i put my heater on high then starts to creep up also when i look into the coolant bottle i see bubbles appear i rev the car and the water level goes...

Thanks for the video link very much appreciated will be changing the water pump hopefully it'll do the trick

I will probably change the pump looks original is it difficult to change one does anyone know?

I have noticed I can wobble my fan a bit but can't tell if it's the fan itself or water pump..?

Have checked rad it's hot all over didn't check thermostat fan test all good thanks

Hi there hope someone can help me my 1995 4.0 range rover overheats after about half hour the temp gauge doesnt shoot up just eases up the heater blows hot I've just had it running with the coolant bottle cap off and noticed the water will over flow out the top but when I rev the car the water...

coolant level was bang on where it should be neva had to top it up

HELP!!!!! just changed rad in my 95 4.0 range rover lpg got air out and everthing running smooth sits at half way on temp gauge when idle and can drive for miles but as soon as i turn the heater fully up in car it starts to overheat turn it down goes back to half way

Thank you wil2813 will give that a try

yeah have been told that before hoping that all it is

well not really a mechanic but know a little after i had rad checked thought id try the thermostat but i have no white smoke no oil in my water no white gunk on my oil filler cap not sure what it is heater in car still coming out hot when i take water tank cap off the water bubbles out

thanks for that had that done there is a slight misfire at low revs too
