Trying to finish up the Car after replacing the supercharger coupler and as I’m putting the bolts back I noticed the long bolt seems to be damaged. (Long bolt towards the front of the lid) Can someone help me find the part number? I’m looking online but have failed to find it. I’m sure it’s a dealer only part or online.

thank you for any help

 

There's two of them, M8 x 150mm.

Part number AJ811189. Not expensive online, so probably wouldn't be the worst cost at a dealer.

 

thank you so much!!!! I was doing terrible job searching and couldn’t find the proper wording. It was even harder without seeing a diagram on most sites.

 

To me this looks like there are remains of the block's aluminum thread in that bolt. So its not your bolts that are damaged but the thread in the aluminum block. Maybe someone overtightened or did not start on the thread when re-inserting the bolt.
If I where you I'd clean the bolts with an iron brush or ideally with an M8 cutter, and then re-cut the thread in the block with an M8 cutter, too. Carefully located the thread when putting the bolt back. Then tighten the bolts with 25Nm. You should be safe if the torque meter triggers. If it does not, you can put in a heli coil or use a similiar thread repair kit.

Chris, you won’t believe how much force I had to use for many of the bolts. It almost felt like an impact was used to tighten them. Who ever worked on the car before I owned it definitely did not use torque specifications.

 

Ouch. These aluminum blocks do not take kindly to that - hopefully they haven't mangled any fine-threaded holes (e.g. water pump)...

 

It’s usually how it goes after buying a used car.. all these surprises are waiting to be found. Luckily this is the only issue I’ve had with a bolt.

 

Clean the threads and reinstall, will almost certainly be fine.

 

Probably just corrosion.

 

Got the new bolt and it went in smooth. Luckily just the old bolt threads were bad.
