Just so I know what I am in store for when I get round to do thermostat.
Have read that you need to replace the stat housing with the 2 sealing rings to transfer pipe,but assuming this is corroded think it might be wiser to have a new one so as ensure a good seal.Am I correct it thinking that a lot of the grief is removing the transfer pipe from stat housing and the remainder of the greif is getting the transfer pipe bolt out and then back in afterwards.
Does anybody have a part number for the transfer pipe and a indication of the time it would require to do job from start to finish as after reading it seems wise to do this sooner than later.

8. 90502201 THERMOSTAT
9.  9128363 THERMOSTAT O-RING
10. 9129999 COOLANT TRANSFER PIPE O-RING (FEEDS INTO THERMOSTAT HOUSING. ORDER 2 OF THESE)

 

not sure of part # for pipe itself, are you sure its corroded? definitely get new o-rings though

and yes you're right, the 'bastd bolt' can consume as much of your time as the whole job!

Thought for the cost of the transfer pipe might be better to have all bits to hand,as thought it was a pain to seperate the stat housing from pipe?
I did read your previous posts on the replacement and it fills me with dread but seems my stat is stuck open so might as well bite the bullit whilst weather is descent and get bits in ready for later in month or early August,so just fishing around for costs of bits needed.

yeah there have been some reports of the transfer pipe being seized onto the stat. mine wasnt too bad but i think a bit of brute force in varying degrees is required nonetheless.

best of luck with it, the pipe and the bolt are the bits that will cause you a headache. get some wet and dry paper as well to clean and rub back the mating surface on the block, you want that nice and clean if you can ;-)

I found it quite easy... what I did was to remove plenum, inlet manifold and the flange so you can get at the thermostat, undo the bolts on the thermostat housing, then get a pair of mole grips and wiggle the thermostat loose (doesn't matter if you mark it as your renewing it anyway). You then need to undo the bolt that holds the power steering reservior and move it back so you can see the "Bastard" bolt. Undo the bolt remembering which order the dipstick, engine lift bracket and the coolant pipe go. I didn't need to remove my transfer pipe as it looked fine.. so I twisted it anti clockwise if I remember correctly and just pull it out only slightly which will then give enough room to remove the Thermostat Housing. You can also fit the two "O rings" on the end without removing the Transfer Pipe.
Once fitted just put everything back again

Try telling that to Hotel 21 with Shifnal in mind.

Three times I have changed a V6 thermostat, the transfer pipe was stuck each time.

The last two I freed by taking a small dremel type die grinder to the thermostat housing. Very carefully cut a small slot in the housing, then crack the spigot with a screwdriver.

If you get it right you can stop cutting before damaging the transfer pipe, or even the O rings. Change them anyway.

Somewhere I may still have some photos taken at the time.

Thanks for words of inspiration.I have decided to be fully prepared as only want car off road for the day.Have got local dealer to order me / stat housing.."o" rings for transfer pipe and transfer pipe..seal for stat housing..stat..and 3 bolts for housing and 1 bolt for transfer pipe..total came to about £45=00 so I think I have covered all eventualities.Picking bits up on Friday so will get 5ltrs of coolant then pluck up the courage ..and go for it !!!
