B230 thermostat housing stud P/N

[T5Sweep]

Annoyingly one of the studs that bolts down my thermostat housing has sheered, does anyone know either the size or even better a part number for a replacement?

52.5mm stud in length M6x1.0 thread, small thread into the block is around 12mm and the longer part of the thread is about 20mm.

No part numbers on Vida.... I've got one which I've pulled out of my spare 530 if you need it.

Drill a central hole in the stud remains, mix up some 50/50 acetone and synthetic ATF giving it a good shake and squirt/driblle this mix into the stud. Let it soak in then use an Ezi-Out on it. Replace with an M6 x 50 hex head bolt, or socket-head bolt (Allen key style) if you prefer.
I'd also suggest using stainless steel for the replacement bolt/stud and either way, a smear of copper grease on it to prevent future seizure.

That would be marvelous, I'll cover the postage if you like bud.

Fortunately it's broken proud of the head so shouldn't be too bad to remove

Hey Ben, send me a PM with your details and I'll post it out.

Any chance you can weld a nut on the bit that's sticking proud.
I have done this many times with my MIG welder with great success. The heat does the trick in freeing off and all you have to do is get a spanner on the nut and wind it out.

No disrespect to Choochs generosity but seriously, if a fastener fails, don't mess about with secondhand :

You can buy one (as a sample) for £1.39 or 10 for £5.80, if one has gone, chances are the others aren't far behind...............

You always want to use studs into alloy heads. Bolts put a lot more stress on the threads compared to a stud and are much more likely to strip the threads.
