    Thermostat housing part # LR005631

    Hi all,

    As part of trying to trace a small coolant leak I need to take off the thermostat housing LR005631 on my 2006 V8 disco.
    Believe it or not I can't find any reference to the part in the workshop manual and there's nothing on the web.
    I as hoping that that some kind soul might have some information on how to go about it, torque settings etc.

    TIA

    It's a 4.4L so not sure that will help.

    I will try and have a look tomorrow in my workshop manual, if no one chimes in beforehand.

    Northiam and Disco-tastic, many thanks for the info.

    By way of explanation, its wasn't the thermostat cover or the system specs that I was referring to, it was the complete thermostat housing assemble part # LR005631.

    Its a wacking great piece of composite that sits on top of the engine, under the throttle body and above the water pump. I couldn't find any info in the workshop manual or on line.

    Any how I ripped it apart this morning but I could still use the torque info if any one comes across it.
    Not a great photo but it gives you an idea
