Would anyone like to claim this

[Plasticman]

This was sent to me with sheared and stuck bolts etc, cant for the life of me remember who by
jog any memories

and

retapped the threads and faced up the mating surfaces
wont supply the bolts as they should be stainless to avoid future problems

Flipping eck Mick that's a brilliant job. Way over and above what I expected. I knew those bolts would not be a problem for a man of your means.

And in my defence I did snap the bolt but I never fitted the bolts originally

Thanks ever so much. Your reputation proceeds you once more

What is it?

[Cruz]

Main body of an early thermostat housing

Looked like this before Mike got his hands on it. The bolt head holding the metal pipe flange on had somehow snapped



Bottom half (025121117A) is sat on my desk looking lonely

Must say I like the name of Mike's photobucket account.............."mentalmick"

Does stainless not react badly with alloy?


-------------------------------------------------------------

Just for if any future members do a search for early thermostat housings

1983-1985 metal early thermostat housing (not even numbered on ETOS/ETKA/VAGCAT)

part number from body is 025-121-117C or 025121117C

still available via classic parts in Germany for £160 euros as of 01/11/2011

See wiki on how to order

Stainless steel is an alloy. If you mean react with the engine block etc I doubt it else why bother fitting stainless steel studs when swapping an exhaust system? (Prays for positive response - having just fitted new exhaust and stainless steel studs )

[Plasticman]

theres often a reaction between dissimilar metals but in this case wiould it be a problem in our lifetime
always liked the old ways with brass/bronze nuts etc on exhausts.and areas thatr were liable to immersion

Hello,

You worry me with your Stainless Steel exhaust studs. S-S will not be high tensile, OK so you're not cranking up to 150 Nm. Black iron studs are DIN 10.1.

Zinc plated studding will not do either, as the plating process drops DIN 8.8 to (category) 6.

S-Steel is inert, this is because of the mix of alloys, Nickel and Copper, also in smaller quantities more exotic 'transition' metals.

It will not react with Aluminium-Magnesium alloys.

Cordialement,

[Plasticman]

its not exhaust in this application its thermostat housing and maybe 20ft lbs ish ish
mm

[Cruz]

And what grade of stainless? A2 or A4

Here is the housing body re-united with the housing cap

[Plasticman]

shouldnt think it would matter on your application
mm

[Cruz]

I assume A4 is just a stronger version?

come on shaun do the google
