2000 EGR vs 1996-1999 EGR Tubing

[SappySE107]

For those swapping from a 96-99 upper intake manifold to a 2000 and newer manifold, will the EGR tubing need to be replaced? I know the electrical portion is identical, but I am not 100% on the parts I have here. It looks like the 96-99 has an adapter bolted to it, and that can be undone and then reused. Just want to verify.

I think the left tube is 96-99, the middle is 2000+ and the right is 3500 (thicker flange to the manifold). Correct?


Part that goes to the 2000+ EGR direct



This end goes to the exhaust manifold

ive never seen anything like this.

both my 96-99 and 00+ stuff screwed into the exhaust manifold.

dont know what the far left tube is from but the 96-99 stuff doesnt look like that and the middle and far right tube must be both 3500 tubes cause again they use a big 3/4 style bolt hollowed out and the tube goes through the middle and is held in the manifold like a compression fitting.

yes to answer the question when swapping from 96-99 to 00+ you need to swap both the egr and the tubing.

Hmm, maybe that is from a 3.4 DOHC. Its possible, I have 2 3500s here as well so perhaps I have 0 3100 or 3400 style. Got pics?

[geldartb]

id go with 3.4 DOHC cause ive never seen it before. the res have got to be all 3500.

the 00+ bolt to the EGR like your last pic so that part is the same.

i tossed the top half of a 96-99 egr tube the other day.

unfortunately i dont have any pics. ill see what i can find.

Yeah, I agree, must be TDC stuff, in fact IIRC from my photo-memory I think they had something like that...

[SappySE107]

Yup, i have a 3.4 DOHC engine in the garage as well and that is what its from.

[geldartb]

why couldnt they have made the earlier 3400 egr's like they did the 3500 ones. two bolts instead of the screw in crap.

My project is on hold because of this stupid EGR tube. The dealer here wanted 100+ bucks for the later model one. I can't seem to find one on ebay.

I went to the junk yard and found one on a later model car, but then I couldn't get the darn thing off the exhaust, even after spraying it with some of that anti seize stuff. Plus it's hard getting to as well. Didn't know the "perfect" tool for getting it off while the engine is still in the bay.

I've been thinking of splicing or making some type of homemade adapter to mate the old to new, when I start on it. Don't know.
