Hello Guys,

Can somebody help me with a 2004 Land Rover Range Rover 4.4 V8 (BMW Engine) Engine cooling diagram?
There Comes only cold air out in the cabin. The coolant-level is ok and i see there are some Valves in the engine to break the coolant-flow on smaller hoses. I Need to know how this System works. This car is also equipped with a pre-heater btw..

Any common faults for this?

I don't know about the water valves on the MK3 L322 but on generally Rovers designs from the BMW period the heating was mainly controlled by electronically controlled air blending doors on the heater unit .
Also I know from other Rover models the coolant side of the heater matrix is prone to clogging up.
The climate control panels are seldom the cause of any issues.

Thanks mate for your help!

Today i was working on this car and the radiator is clogged up and the heater-radiator as well. The owner put some "stop-leak" fluid in the system and now is all clogged up. I'm done with this car!
