[W126 Coupe] Exhaust manifold bolts?

[Steve Nervig]

Hi, Mike,

I think the plain old Kroil is what I would use to get exhaust bolts off. I think the other two would be where you want some sore of lubricating system left on the part after it was broken loose. In your case you will be cleaning the parts and reinstalling with a high temp/anti-gall/anti-seize substance like a moly-coat, no? 

I'll bet that you could also call KanoLabs and they could tell you the straight poop.

Steve
