Physically, I can't see how it could.

Hmm, seems weird that if they installed a new one, that its leaking already. But then again, its possible they didn't get the improved version. You won't know until you take it off and look at the EGR hole. And please do take pics if you can.

Yes, I will tear it down first and take photos. At the least I will be replacing gaskets in the upper and lower manifolds. I will show the intake in photos so I can be guided.

In the end from what I have priced they are both about the same, and the shipping should be the same as well, I think it is about 5 business days for either, I do not have Prime anymore, but for anything over 35.00 I always get free shipping, and it comes within 5 business days, but of course RockAuto has a more solid warranty, by that I mean I have heard of some trying to return Dorman auto parts to Amazon, and been told for some reason that they had to send them directly to Dorman.

I would check the throttle body gasket myself before I started tearing the LIM/UIM down. That is about the highest point that coolant flows that I can think of, and I suppose could put coolant in the area where you found it if the car was parked sideways on a hill leaning to the drivers side.

That is possible I suppose, when I went to remove my throttle body gasket from my old UIM the plastic of the UIM that holds it in places fell apart.
They still need to replace their LIM Gasket with an aluminum one though, so a tear down is in order either way.

i am impatient so waiting for parts isnt fun for me. i have always just got their free shipping and if you watch when they ship on the status thing they used to ship it within a day or two and usps would be the thing that takes forever, but recently maybe last 4-5 months they wait 3-5 days before giving it to usps still so it takes a couple weeks. to me prime doesnt make sense, if you get it from rock auto they will fedex or ups it in two to three days for 10-12 bucks

I'm skeptical its the TB gasket. Unless someone took the TB off before and damaged the gasket and never replaced it.

Doesn't the throttle body have to be removed to install a new UIM? I don't have a shop manual yet for this car. What is the procedure; diagrams would be helpful. I know that coolant has to be drained and fuel pressure relief so the fuel rails can be removed, but if someone can help with a procedure and some diagrams it will be nice.

I found someone else that mentioned coolant in the air intake duct on a website search.

"On march 13, 2008 I took the intake manifold off the engine and found antifreeze in the intake duct going to the air filter and antifreeze pooled in the intake manifold. This was caused by two separate defects, the upper intake manifold gasket not sealing properly to the lower intake manifold (was leaking in two different spots) and the leaking throttle body to intake manifold gasket (was leaking coolant into the intake duct to air filter)..."

Since the UIM was replaced with the new and improved designed (although the LIM gasket should be replaced) could I check the TB gasket first? Would the TB gasket leak coolant back inside of the UIM? If so, then I guess I would need to remove the UIM to remove the coolant that has collected there.

Any info or links to diagram will be appreciated; I like to learn as much as possible before tackling a job. The shed currently has a tractor that I am working on so if I need to take all the intake apart, first step is to try and get the tractor out of the shed; wish I had that project finished.

I think that any coolant in there would have been ingested already instead of pooling inside. Some UIM kits just don't come with the gasket, and it'* easy to overlook if you aren't thinking about it. Given that they haven't checked the coolant level since, and the car hasn't overheated, I gather that this was done fairly recently. Have a look between the metal throttle body and plastic UIM. There should be something there, common colors are blue, grey, and orange, and the gasket is usually plastic.

You should be able to unbolt the throttle body and swap/insert gasket, then bolt back up, it'* just a matter of removing what'* in the way.
