OK, so I plan on doing the UIM replacement with the LIM gaskets as well here in the next month or two. Lemme make sure I have everything that I need:

GM Aluminum Frame Lower Intake Manifold Gasket set: GM PN# 89017816

Just those two, correct? Or am I missing something?

Thanks.

Chris..you will need coolant elbows, throttle body cleaner and there'* something I'm forgetting.

Throttle body cleaner is a no brainer. Got some PN'* for the elbow'*? I can pick them up while at the dealer for the gaskets, or if they are cheaper at the parts store, I'll go that route as well.

If you search (I'm too busy at work) you should be able to find the HELP part number. They are made by Dorman. Autozone usually has a set in the store for $4

Don't forget the brake clean and oil absorbant, probably no brainers..but the newer folks with less experience may not know how well brake clean on a rag cleans a gasket surface of all oil/residue.

Oh definately. I've actually used brake clean to degrease an engine bay before. Was working soooo much better than the engine degreaser or even simple green was.

Yeah, I'll do a search to make sure I have everything that I need.

One thing to look at ahead of time/consider. there is a small bracket on the front side of the throttle body.. 8mm bolts hold it to the intake manifold. Take a look at it and decide how you are going to remove it. There is no easy way with the crossover in place..however a well placed wrench will usually work.

Also..consider having a 6 point 10mm and 6 point 3/8 sockets on hand. Many of our "10mm" bolts fit better in a 3/8 socket than a 10mm.

I have about 10 different 10mm'* sitting in my toolbox at work, I think I have that covered!

I'll take a look at that bolt though. I'm sure I'll come up with something ingenious to get it out.

Instead of hogging this thread, I will just create my own.

he is not kidding about the 3/8
I went and got the uim long story but I will be putting it together tonight with a little smoothing first. and it was the coolant passsage in the lower that failed

I literally bought a 3/8 this weekend knowing I was pulling my intake and Pete was also changing his gaskets.

Interesting tidbit. on the intake, oil pan and valve covers the 3/8 fits perfectly....all other 10mm on the car it simply won't fit. GM was hosing us knowing 3/8 bolts were very close to 10mm.

I am not going to complain alot here but the APN is the biggest waste of money I have spent on this car I will not buy from them again. go somewhere else. I have to completely take off the lim again to get that all to work right I am highly mad
