Default Newbie needs explanation

Hi, I have a 2000 ssei, I have a problem keeping coolant in the reservior. It dont see a leak but sometimes I smell somthing burning after I park. What exactly is this UIM and LIM. I have 129,000 on my car. It sounds like something I need to do for preventative maintanence. Please advise.

You do not have a UIM, only the L36 does. Most likely your LIM gaskets are failing, and they need to be replaced.

Odds are you LIM gaskets are seeping coolant into your motor at a slow rate. Not at all uncommon with the miles you have.

Make sure you replace your valve cover gaskets while your in there.

INTENSE RACING sells a kit for cheap that includes all the gaskets you could dream of.

Oh yeah and the cooland elbow..do that too.

I am having the same problem and am getting ready to do the work on the 96 SSE/ L36. I have a UIM but you don't so only about half of what is written here will apply.

If you were closer I'd suggest a meet up and fix up.

Ok Ok Ok Ok......Thanks for the replies, but I have checked a few threads and is this something I really want to get into??? It looks like I have to literally remove the engine. Is this true?? I dont want to sound really stupid, and maybe asking this question will prove why I should not attempt this, but where is the LIM located Does anyone have the Alldata view, or an wide shot view of the motor that I can see where to start. Thanks fellas!!!!

This is for a 2003, but it'* the same as the 2000. The difference is that their demo is for the L36, not the L67 like yours - so, the supercharger portion won't be there.

Intake Manifold

Alright!! That is what I thought I was dealing with . So it is just the gaskets on these things that are bad?

Pretty much mostly the gaskets. The GM aluminum framed gaskets should help a lot. There have been some LIM that have had some severe pitting, and needed replacement.
