See pictures - this is on the rear of the engine small rubber connector between the bottom of the block and the upper plastic part.

Any help would be great. Leaks like crazy once the thermostat opens up.

Wow, great find.

Let's give it up for gisham :clap: :clap:
That's the one! Thank you much.

RR part number is: JHC000081 In case anyone needs it.

If you have a 2003 - 2005 with the bmw engine and have 75K + miles i would look at this hose on the back of the engine to see if you see any of the "orange" coolant leaking signs around this part. 10.00 and an easy install. Would have saved me a lost weekend expedition.

hehe, yea i just ordered one myself-
Thanks I needed this part to. I just gone done replaceing the radiator and all the hoses but I missed this one!!!
This is why I <3 this forum...The dealership wanted to charge me over $300 to fix this... :naughty:

A lot of people who complain about LR's being extremely expensive to maintain never really do any research :dance:
Ok, so my part came in...and I can't really see/reach it...do i need to take off the whole part that is holding up the pollen filter, etc????????

Yes, and the engine cover.
yea guys wondering where this part is located myself. I've looked in there and cant seem to locate it. Can anyone explain what they had to do to replace this part?

Yes, engine cover off, pollen filter off, get on a step stool and look behind the engine towards the top, you will see it. From there is a matter of popping off the BMW quick disconnect from the fender side, and unscrewing the hose fitting from the heater core. At this point fit the new one, screw it down, click the quick disconnect back together.

Might want to pull the res cap off then pull a little fluid out of the system before you start.

Thanks I'll take a look when I get home. Local shop wanted $150 to replace this how which sounds ridiculous to me no way it should take more then an hour.

$150 is pretty high considering how quick a job it'll be for you. Once you get the engine cover off and the pollen filter out, it's no problem on a step ladder. Very easy access and you basically need 3 tools... I think the pollen filter is 2 13mm bolts, the hex for the engine cover, and a flat head to screw driver to clamp the hose down.
