Need some help identifying a bolt.

TinCanSailor · 04-29-2021, 04:04 PM

I am hoping there are so similarities between the F10 M5 and F06 M6 that this might be a shared component.

I had a long approach walk up to the front of my car today and happened to notice something hanging down around the front center approximately under the radiator. It was sticking out from the belly pan and I though it was a cooling tank expansion tube or something from the AC cor condensation. Admittedly I am not under the car a lot as I have had the engine swapped and work out of the country pretty frequently for work.

The pictures below are of the bolt that I removed after returning home immediately after seeing it. I am hoping someone can give me a good idea of where it is installed. I'd like to work on it at home in the garage but given the size of the bolt I feel like I may need a lift or lifting tools that may not have on hand. I am not sure if this is a sub frame issue or something heavy.

I do have set of 4 Rennstands and a good floor jack and all sort of hand tools but just not sure what I may up against with this.

This is the bolt dangling from under the car. As I walked up it looked like a black tube but something in my head, likely OCD related, told me to bend down and take a look.

Perhaps the aluminum subframe brace bolt? See if you can take the splash shield off and confirm they are all there.

Thanks for the tip. I plan on getting under the car on Saturday. Hoping it is an easy to reach spot. I was thinking subframe bolt given the size but have never put my eyes/hands on them in the past.

That is for the aluminum support frame near the engine oil drain area.
All the bolts are installed from under the vehicle when it is up on the lift

apologies for not following up sooner. My son and I got the car up on stands this last weekend and found that the bold came from the front left subframe. Installed and torqued to 70 ft lbs.
