most off you know that the sec. gen lower I/C boots can rub on the body causing a hole to blow in them (how do I know this ) well I was servicing the trucks last weekend and found 3 of them had this issue and the 01 HO had popped the left one . after calling around I found 1 at the junk yard for $45 ...needed it. dealer parts dep. $135.I think there smoking dope!
but for $50 i got some real nice HD ones from piers.

for them thats not looked at there I/C boots bend that metal tab away!

 

I found the same thing with my 02. Lower driver's side boot had started rubbing, but I think I caught it in time.

 

My Brother Had The Same Problem With His 01' Bu He Was Able To Get Some Used Boots From A Local Salvage For $10

 

Why do these boots cost so dang much anyway? I've always wondered about that, but even more so now that I own a turbo Buick. I can get a complete set (5 boots) for my Buick for $40-50. The ones they have for the CTD are outrageous...

 

The CAC inlet/outlet are an odd size and have to be custom made for this application. A regular 45* transition hump hose won't work.

 

man i wish i could find parts used like that i live in northwest ontario canada and you can't find any diesels in any scrapyard !
