Please tell me you're REPLACING your entire UIM at the same time? That is actually more likely to be your problem than the LIM gaskets, and if it isn't, it'* a timebomb. Do it all, or don't bother.

I had the UIM replaced already, and I flushed the Dex out at that time. I haven't had the LIM replaced ever, and it is the only thing that'* leaking now. I was going to just go for the lowers this time since I had the upper manifold and gaskets replaced earlier.

Are you going to at least replace the UIM gasket then? I wouldn't reuse a UIM gasket...

I think what he is wondering is if the LIM and UIM can be removed as one unit so that he doesn't have to replace the UIM gasket again. Correct me if I am wrong.

I am not sure if there are any bolts under the UIM that would necessitate the removal of the UIM. If there are not, then I don't see why you shouldn't be able to remove them as a unit.

If you do have to remove the UIM, I would suggest at least replacing that gasket for the reasons mentioned above. It'* been 3 years, so even if it still looks good, it'* good insurance/piece of mind to do it rather than reuse the old.

And I like the spray bottle idea for removing the excess coolant. Never would have thought of that.

If that is in fact the question, the answer is no.

You have to remove the UIM to access all of the bolts for the LIM.
