Currently checking all my TF (2004) hoses. Have come across the following one the Rimmer website PCH002792. The hose assembly consists of 6 parts. But for the life of me cannot work-out where these hoses on the car! Or at least cannot see them.
One of those hoses in that assembly has a bleed screw on it and is listed as such. It is therefore one of the three coolant bleed points. I'm guessing it's the one behind the black plastic trim panel at the back of the bonnet space, on the right (as looking into the bonnet compartment from the front of the car). Things might become clearer if you take that plastic trim off and have a closer look.
