After a day spent trying to remove and replace the seal on the Thermo housing it has resulted in the car now of the road due to a broken flange on the housing unit. How can you change the seal on the housing if you are unable to turn the housing over as it keeps fouling on the engine block to locate the seal in the recess. Undid the flexible hose but there is a bracket theat fouls on dipstick. Are you able to remove the housing unit from the metal pipe and if so how, since it will be surely stuck on from all the heat etc. I need ideas as the car is needed. Ordering a new housing unit,seal and thermostat on Monday so will hopefully get it fixed next week.
Advice please

the coolant transfer pipe that runs from the stat to the main rubber cooling pipe can be removed, take out the commonly referred to as 'b@stard' bolt.
Its on the bracket of the coolant transfer pipe, bit of a pig get to. Take off the PAS pump bracket (10mm) this allows you to push the PAS pipe down enough to get a 10mm rachet spanner on that bolt.
You can then slide the coolant tranfer pipe out (after some damn good wiggling)
I would suggest changing the whole housing including the stat while your there, make sure you also get the 2 extra o-rings for the transfer pipe, they are NOT included with the stat kit.

When I did mine the transfer pipe actually came with the two O rings attached. Shame really as i'd bought two more O rings as well!
-
Yes a new transfer pipe does come with two new o rings already fitted :y
You need like already said mate, to seperate the transfer pipe from the thermostat housing to enable you to remove it.
-
D'oh, my apologies, didn't realise the pipe came with o-rings :y

Thanks everyone. My fingers are now red raw and i am really peeved of with this.It thought it would be an easy job not that difficult. Working in the cold really makes you feel disgruntled. :(

No job is easy on a V6 ;D
When i did the stat, good job there was not a swear pot in the garage. Years wages would have gone into it.....

The cambelt change was easy compared to this. Although i did have the DVD :y

For years I used spend hours scrubbing under my nails and getting bleading knuckles when they cracked due to the swarfega.
Latex gloves are the answer. They can get a bit hot and sweaty in the summer but they really do help to keep the hands warm in the winter. (and if you do injure yourself it keeps the cuts clean)
If anyone gives you grief all you need to do is pull the gloves on with a certain look in your eye and they won't give you any more trouble. ::)

Second that. Its handy on days like today when its a bit chilly out, almost like wearing gloves. The bugger is when they get covered in oil, after a lot of work. Your hands are sweaty, so the replacement pair are a pig to put on.
-
Yes using Latex gloves but had to take them off to locate the bolt on the bracket. Can someone please tell me what the torque setting is for the bolts on the Thermo housing are.
Cheers

I've gone soft in my old age too! (ooer ::)) and, like you always had ingrained oil & sh1te in my fingers. We have some rubber faced gloves at work which are brilliant, you can still feel what you're doing when you can't see. And they keep your hands clean too!
My Dad swears by them too! ;D ;D ;D

Has anyone got a Haynes manual which states what the torque settings are for the thermo housing.

Not here, at home, 25Nm is in my head though :-/
-
so it looks like i need one from a 3.0 auto v6 then, would it have to be an elite or could it be a gls, can't see the vehicle spec making a difference

Spec has nothing to do with stat, engine year is more imporant :y

Why do Vx dealers quote 'Thin' & 'Thick' flanged ones? Newer ones thinner? :-/

Seems that way .. when Pete/Daz did mine they had to find some slightly shorter bolts .. the originals would have "bottomed" before actually clamping anything .... luckily they knew about this so did not even try ... appears you can do a lot of damage if you don't realise ... :(

I got caught by that one ::) screwed bolts in finger tight and they were nowhere near clamping the flange. Got a bottom tap out of the toolbox & carefully cleaned the threads before noticing the difference in flange thickness.
Ended up using solid washers with the original bolts. I did consider putting the wax capsule in the original housing but decided not to. I could have ground the ends off the bolts but was getting a bit fed up by then....
-
I just cut the bolts down....hence why I always get the thin flange variety as I can guarantee to finish the job
