Exhaust mounted with coil nuts

Remco 27 February 2005 01:34:55
 In stripping the axhaust off my 75 bug, I had no choice but to split
most nuts because of rust.

They were all coil nuts for some reason. (nuts with a helicoil inside
-- usually used when high stress applications).

Does this application require hardware like or is this just overkill?
Maybe that's what the guy happened to have?
When I put it back, can I use regular nuts?

Probably the OEM nuts. They're nice because they *do* split readily.
But, you can use plain ol' nuts.

 Yeah, I was very happy to see that splitting them was not a problem :)­
My nut cracker tool didn't have enough room but a sharp chisel worked
well.

Thanks!

 The OEM nuts (the ones you took off) are self-locking nuts, so it would be
best to continue using them (new ones, of course).

The brass nuts are hard to find. Some places sell "copper" nuts for
the same application, but if you put a magnet to them they are just
steel nuts with a thin copper plating. They are little better than
plain steel nuts.

Is there a reason not to use stainless steel nuts?

VW Part: 311 101 463. They used them right up to the end of production in
2003.

 Use the original as they are easy to get off and lock on. I have a bag
of them.

Stainless would be great too 0- when the time comes, I'll get what's most
available.
I am just thinking when the time comes to take the muffler back off. What
was on there were totally fused to the studs.

I thought I tried to buy them from VW years ago and all I got were
just plain plated steel nuts. VW was happy to sell me SOMETHING; it
just wasn't what I was hoping for. Have you actually bought some?

I completely agree that the cars all came with them right up to the
end; I just thought I was unable to buy the same part even when they
ordered it from the VW distributor.

If you order them using the part number, then they should come through.
Some Dealers are tricky though and will pass off anything they might have in
stock. It can even happen from the main warehouses without the dealer
knowing, but the part number is still available so I would try again.

 The ones I got are copper-beveled and come off without busting the
studs. I got the last bag from JCW
