I also replaced my water pump and thermostat only to have my engine get torn down 5 months later due to something else.

I ended up using Belmetric to get some SS bolts to replace and they worked great.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I cannot for the life of me find which bolt I need for the clamps that hold the exhaust support to the exhaust itself. In trying to remove one it snapped the bolt in half. And if I can't get one at Porsche tomorrow I will happily use one from Ace or Lowe's in the time being but I cannot figure out what size bolt it is to be specific.
It�s an m8 x 45mm bolt. The problem is you snapped it off in the nut and it�s gonna be pretty hard to get it out of there. I would cut the nut off and just go buy a bolt and nut to secure it with.
Also a standard u-bolt exhaust clamp would work until you get a new stock one.
New clamp is relatively inexpensive 7-13 bucks.
Thank you. I'm really hoping i can bake the broken bolt piece out of the nut. I'm not sure i can bend that clamp wide enough to get it off the exhaust pipe. And I sure as heck don't want to have to remove the entire pipe. I only removed it to remove the engine brace.
I just replaced my water pump and thermostat, and this bolt was the hardest part (funnily enough).
Thank you, i don't know why I have a hard time navigating atlantas site to find those diagrams.
Its clamp #13. Looks like bolt comes with it.
Is there a trick to getting tjay clamp open wide enough to slip off exhaust pipe?
It's all oem. Refer to the diagrams above. The single C clamp uses one bolt. Flat bar is bracket that secured exhaust to engine. The clamps in your pic look after market.
Same for a mkII. The clamps you showed are for connecting the cat to the muffler and tips to the muffler. These clamps secure the pipe to the engine mounted support.
What is alternative to stainless?
The nut i think is welded on so hopefully can find right threading.
Thanks for all the replies btw, i know this is a minor part, but after doing water pump, thermostat, and some new water pipes, a kicker to have this piece be the hold up completion
Oh and the rubber speed nut that holds the air pump shredded too, so then had to remove the entire bumper
I had a similar issue with one of those speed nuts on the air pump when replacing my coolant tank. I also replaced my water pump and thermostat only to have my engine get torn down 5 months later due to something else. It also turned out that I accidentally bought the water pump for the turbo. The car didn't go any faster.
That bolt is an M8x1.25 and should be available at any good hardware store. Stainless steel will be fine with the regular steel nut that's on the clamp. You could put some anti-seize on it although that does not help much with exhaust bolts.
Yup matched the threading at home depot and managed to find ONE M8x1.25 40mm cap screw , in a totally wrong section. Zinc plated.
EDIT::: Neither old or new would go in, but managed to force the "old" in, and the new in the other side. holy crap that was a study in patience.
Sadly it doesn't fit
Looks almost identical.
It will however go in the other nut, so something is stripped in this one nut. Man it's always something !
The OEM bolt won't go in either, and threading from back side it's really stiff. Hoping can rethrrad the bolt, otherwise arg. Need this all done before tomorrow morning's 996 group drive.
Run a tap through it. An autoparts store will have the tap on the shelf.
I think those nuts welded in the claps r pinch thread (stover) nuts so the bolts wont vibrate out but im betting yours is damaged some.
Here is the solution. Pull that clamp off.
order a new one.
go to AutoZone and get one of these and maybe a 2 inch.
temporarily fit until the new one comes.
or put a smaller bolt and nut temporarily through the exhaust clamp you have.
I managed to get the new bolt through with some muscle. When I have to remove these next time will cut them off and put new ones on.
Thanks for all the feedback!
When I was doing my coil packs, I removed the mufflers. I did not want to put the old bolts for the double connectors that hold the mufflers to the cats back. I ended up using Belmetric to get some SS bolts to replace and they worked great. They had a great selection of just about every kind of metric fastener you can imagine.
A set of metric taps and dies is standard equipment for Porsche, BMWs, Audi, Toyota, Honda owners who work on their cars. You could have chased the thread with an M8x1.25 tap because clearly the clamp threads are messed up.
