One-Time Use Bolts for Underbody Shielding?
My E86 has one-time use bolts (stretched past torque) on its reinforcement plate so it got me wondering if the E84 did, too. Are bolts for any of the underbody shielding one-time use parts?
Now that I can finally open the hood, I can finally start on my maintenance backlog. To do so, I'll need to get underneath but want to make sure I have everything I need before I start. I wasn't having much luck looking this up so I figured I ask this here. TIA

When you say underbody shielding, are you talking about that big plastic tray screwed to the bottom, that is a barrier between the road and the engine?

Inclusive of it. I don't think those bolts are but I'm not sure about the "rear engine undercover", which I also cant find torque specs for.
I'm going to be changing out the trans fluid/pan/filter as well as the coolant and intercooler as part of my maintenance list.

Usually only bolts that are torque to yield (ex. 90ft lbs plus 1/2 turn) are one time use. The 1/2 turn in the example I gave is where the bolt gets stretched.
I doubt bolts for under shielding are one time use, those shields need to come of for maintenance. |

Thanks, guys. I didn't think the plastic guard would but one never knows. Are there torque specs for those bolts or just 'tighten until snug"?
