looks like its coming out of the housing where it seals to the block hope this helps.

Yeah i was just wondering what that bits actually called? and if it has a gasket? I need to run down to london thursday and could do with sorting it before then!

Its called the cylnder head flange and they go for a pass time, your better off getting a geniune one as I've just found out 

[madmanmavis]

Do i want to know how much? was it hard to fit? there looks to be a sensor in there?

Im assuming fairly simple job just a case of draining old coolant etc and replacing?

Cheers Matt

There are two sensors in there (ECU temp sender and Temp gauge sender) all you do is take them out, take off the hoses and then remove the plastic flange. Then its a case of cleaning up the surface of the head as much as possible and putting the new one on, refitting all the other bits and then refilling the cooling system. I would be supprised if a genuine one cost more than about 10 or 12 quid

Thank you sir, so im advised to replace with genuine? is there a gasket to replace as well?

[Uruk Hai]

You should get a rubber O ring with it, and I would get a genuine one as I replaced the other flange thats on the end of the head with a non genuine part and it lasted about 12 -14 months so now I've got to do it again so I bought a geniune this time and should of the first time. Make sure that the area where the flange bolts to head is clean and flat, good luck
