Another disaster!

[arcturus]

Crack in head to rad coupling, don't know if it will weld. Help needed in finding another. B16

The Dutch vkv club web shop has a used one apparently

https://www.volvokv.nl/onderdelensho...athway-2432025

The part number appears to be 403160

I would expect a decent welder would be able to repair.

I've heard about interweb-people using epoxy glues like JB weld for problems like this - I'm not sure if I'd have the gonads to drive a fix like that though (!)

Would a stat housing from a later engine not fit? Looks similar (ish) to the housing on a B20...

Perhaps if you put some measurements up, someone can compare their own?

(I've got an old B20 housing kicking about somewhere I'd be happy to measure up for you)

arcturus;

I wouldn't call it a disaster yet...its way better to notice an impending failure while your under the hood/bonnet for other reasons, than to have it fail "on the road"...now that would be a disaster!

That is a cast light alloy (alu) piece which can be welded...but beware(!) that fracture is suggestive of uneven tightening...so make certain when replacing with repaired OR other, you tighten both securing bolts evenly, to prevent one-sided forces!

Cheers!

Hi George, this isn't a disaster.
Common I would say.
The B16 is made of cast iron if I remember right. Don't try to weld it.
You will fix it (temporally limited) with JB weld very well. At a strap made of stell from one screw to the other on top of the thermostat housing to get out the stress of the crack. We drove a car a few years with a crack like this, totally forgotten the "short time fix".
You will find another (used) one, I'm shure.
good luck, Kay

As you can see the 'stats are a completely different size. The bolt holes in the housing are 2.75" apart or 70mm.

Will send you a private email later. forget that. Bought one from Sweden €15 including shipping

arturus;

I'd use a a Tstat Housing repaired by welding, but not by JB Weld (essentially a metal filled epoxy)...when properly welded, the part is once again monolithic...but that is not the case when repaired with JBW...because the then (filled) fracture remains, and the forces (which broke it in the first place!) still concentrate there, and will likely break it again... JBW has its place (ideally in compression or for making up lost, unstressed material), but not here IMHO!

Cheers

Good deal!

It might fit using B18/20 'stats. Would be useful to know. Could you measure yours and also the hose fitting size?
