Thread: UIM questions

1. How does one plug the coolant ports in the UIM?

2. Is the EGR tube necessary for the revised UIM?

If you got a NEW UIM, it has all the updated features that you need, so that the problems dont happen again.

No need to delete the EGR or block the coolant ports.

Sorry Cam.. I've seen replacement manifolds have trouble over time as well. The plastic cracks over enough heat/cooling cycles.

Here's the what happens

Alright thanks guys. The new intake didn't come with an EGR tube so I'm just gonna figure I don't need it. It does look a lot better around the passages then the original. Thanks. I'll probably get this done this weekend. Don't wanna go through the horror of hydrolock again.

It should have came with 2 stove pipes. I've never seen them not come with them.

Interesting. All it came with was a new PCV sensor housing/clip and the gasket plus the UIM itself. It's been installed without one for a couple days now, according to my dad.

Drill...tap... plug. That's the only sure way you can't hydrolock again.

Alright Bill. Thanks. So I take it with the plugged ports I don't gotta worry about even having the stovepipe?

I'd have a stovepipe. Because those hot exhaust gasses shouldn't be direct in contact with that plastic UIM.

Remove the fuel rail. Four 10mm nuts. Remove throttle body. Three 10mm nuts. Remove all the UIM bolts. I don't remember how many, but they are 5/16 believe.

Those hidden bolts are for the LIM. There are 12 LIM bolts.

Like those above..I forget the number of UIM bolts, they are 8mm. I pull the fuel rail off, then the UIM with TB connected. Unless you are going to clean it.

At this point you are looking at the LIM. In the front drivers and rear passenger corners there will be a pool of oil. Stick your finger into the oil and you'll feel the head of the bolts. Clean up oil and you'll see the bolts. 12 bolts.. count them.

One more quick question. I already have everything I need to block the coolant passages and I'm doing it Saturday. I still want to put an EGR tube into the UIM. So I'll go to the junkyard and grab one from some L36. My only question is, do they just pull out? And then I'll just push it into my LIM? Or is there some magic trick.

Thanks!
