P38 climate control affecting Engine temp

<< < (2/2)

Range Rover Blues:
Just a thought but on the saft dash classic they introduced a valve in the heater pipe that shuts off hot water to the heater matrix when both controls were turned to cold.

COuld this be something to do with it?

Not having read what the RAVE CD says about your car yet I'm clutching at straws but unless you changine a heater control is just a coincidence then there must be a physical link, whether it's the electric AC fans, the water flow or even the electrical input to the engine ECU causing a problem I don't know.

andycwb:
AFAIK the heater matrix runs at full flow on the P38A at all times.

Turning the temperature up means less A/C loading not more, and more heat loss from the heater matrix into the car, so I really don't see how this can happen unless there is some kind of airlock.

Try asking on the forums on www.rangerovers.net - they might have an idea.

I have had the radiator pressure tested and it i apparently 70% blocked so I have ordered another one and when it arrives I will update this thread.  I am not convinced it will cure it but I have my fingers crossed !

Range Rover Blues:
OOOh, 70% blocked, well it's not doing you any favours :wink:

Fingers crossed for you that that sorts it out.
