Long shot, but does anyone have a coolant transfer pipe for the V6 engine.
Need to do a thermostat change, and I know the transfer pipe is going to brake, so trying to locate one first.

[Dave G]

It shouldn’t break unless you’re really rough with it.
The difficult part is getting the mounting bolt undone. Was for me anyway - goes at a slight upward angle into the block.
Once that’s undone, top hose off, gentle wiggling back & forth should loosen it. Twisting motion rather than just pulling.
Then a good clean, bit of vaso to refit and I was away.

I’ve had the same pipe off & on about three times now with no damage.

Just take it steady.

Replace the O rings once it's off.

Yes, defo have the o-rings - 2 from memory - for the thermostat housing to transfer pipe. Also have an o-ring for the thermostat housing to the block - some thermostats come with them, some don't.  Additionally, be aware that if the flags on the new thermostat housing is a different depth, you will need different length bolts as well.

I had the idea a long time ago that the thermostat could be removed from  / replaced in the housing without removing the transfer pipe just just turning the housing upside down in the valley of the engine.
I cant remember whether or not I managed to do it though.

....... Additionally, be aware that if the flanges on the new thermostat housing is a different depth, you will need different length bolts as well.

Or a stack of washers ....

Pretty sure I do. I’ll check when home on Tuesday 👍

The thermostat can definitely be removed as a separate item, as I’ve done the old boil in the pan to test trick.    You just push the stat down a couple of millimetres and turn the arms out of the castings.  I don’t see why you can’t achieve what you are suggesting.

Which begs the question - why do we go to all that trouble and replace the Stat with housing as a matter of course ?

Annoyingly I'd already removed the transfer pipe to do it when I tested mine. 

[cam.in.head]

its because the removeable part of the thermostat is only half of the sealing valve .the other half is the alumunium housing which can become worn and pitted hence leaky !( this is the usual failure mode anyway - letting water past )

[Migv6 le Frog Fan]

Usual issue though, ime, is lazy Stat resulting in engine struggling to get up to temperature, which doesnt help empeegee figures.

Maybe the pipe still has to be separated from the housing to allow the housing to be turned over far enough to remove and insert the new Stat ?
My memory is so fuzzy !

There's not a lot of wiggle room for sure
