We just learned that the newest Dorman UIM kits are supplied with a reduced diameter stovepipe that will fit the 95-98 LIMs. If you are going that way instead of the APN (a better choice) try to find one of these newest stock items.

So still APN is a better choice? Prolly because of that metal bushing around the stove pipe?

also, does anyone can recomend online GM dealers, so we can make online order?
tnx.

cheap, but not the fastest shipping.. there are others, but im not going to recommend since i have not used them

thanks a banch for quick reply.
This is a good people on this forum, unlike some others forums I dealing with.

Yes, the APN is better because of the metal sleeve or bushing around the stove pipe. It acts as a heat shield to reflect heat away from the plastic underneath. A reduced diameter stovepipe and a heat shield are the best long-term fix for the UIM without altering the cooling system. The newest Dorman UIM kits come with two reduced-diameter stovepipes: one fits the 95-98 engines, the other fits 99-05. But the Dorman still is not as good as the APN, because it has no heat shield. Plus, the Dorman kit costs more. I advise people to buy the APN before they need it. If that is too large an investment, then I suggest they buy a heat shield or a shielded stovepipe and toss it in the glovebox. Then when they are ready to make the repair, they can buy a Dorman locally and add the shield. This is less expensive for the initial purchase, but more expensive in the long run.

Finally got time to continue work on this.
BTW, took 2 weeks for guys from gmpartsdirect.com to send me respond on my inquiry.
Still shaddy for me. I don't get it. For example searching for part 89017816 (intake mani gasket set). Result saying that pack qty is 1 for price of $36. What does it mean qty is one, only one gasket??? not a set of 2? hmmm.
Same with spark plags, qty of 8 for $3.25, the sence of reality telling me that its not possible. So wus up with the quantity thing when order? How many pieces go for each part #?
Thanks in advance boys.
Oh yeh, and one more thing, is any other online GM dealer with a little quicker respond time?

we finally get the time and trying to finish our project.
I decide to change water pump and it gasket and I got to the point that I need your guys help. As you can see from the picture, one of the bolt, next to the power steering? pullies is not come out far enough to let water pump off. How do I do that? Should I remove even more parts to be able to replace water pump
Also went to couple of auto parts store, including Auto Zone and can't find that bypass coolant ellbow, any suggestion who may have it? What brand water pump is good for our car?
Thanks in advance,
Alex

Remove the bolts for the PS pump and rotate it back out of the way towards the firewall.

Thanks for quick reply. Is it any way I can get to it from the top, or I need to go under the car? Should be 3 bolts, really hard to get it?

Should be from the top with no problem. 3 bolts. One of them is accessed through the holes in the PS pulley.
