308 air pump removal -- bolt is too long to get out!

My friend is trying to remove the air pump from his 308. He's got the air injector plugs and knows the pros/cons of emissions equipment removal, etc.

The problem is, there's one long bolt that holds the air pump to the engine. This bolt has to come out to remove the pump. The bolt is long, and cannot get out all the way before it hits the oil cooler shroud.

OK, so the oil cooler and shrould (or shroud only) can come off via three 10mm nuts. But, there's still not enough room to maneuver the air cooler shroud around and/or out of the way of the bolt.

Anybody been there, done this?

 

Yep, Tom that was exactly it! Thanks for the timely advice.

There are THREE 17mm nuts you have to take out to remove the entire air pump mounting assembly; I used a 3/8" ratchet w/ standard shallow 17mm socket.

Now, that's left me with a number of "studs" inside the engine block; do these come out nicely?
