I believe, if you have removed the bolt roughly beneath and forward of the oil filler, then it is just held on 2 O rings. That said often a bit of corrusion in the joint can cause it to stick.

It is best to use two new O rings on refitting and possibly a new pipe.

Good luck with refitting. You need a bit of patience with that bolt!

I remove the two stat housing bolts and use a set of grips to rotate the stat housing on the link pipe to free it off before removing the B-bolt

Ive just bought a new tube ready for tackling this job  :y

are you meant to use any sealant on the new stat, or just oring?

seem to recall something about a smear of camcover goo worth applying?

I used silicone grease on the ones I have put in.

The problem seems to be caused by coolant getting into the grooves behind the o-rings and the resultant corrosion expanding and crushing the o-rings. The corrosion appears to be slightly porous and acts as a wick which allows coolant to bypass the o-rings and escape (slowly).

I use a wipe of oil cooler goo on the stat to block face.......and a wipe of grease on the link pipe O rings.

Link pipe is around a tenner with new seals
