I've seen a few posts about this LIM problem here. Is this a serious problem?

I think i may be experianceing this. My coolant has been slowly leaking for some time now i thought it was just the lower rad hose <I could see a hole in it where the DEX was commin out> so i changed that. but a few days later my coolant light was commin on and sure enough i still have a leak.

where exactly on the car is this LIM gasket and how can i check it out myself b4 takin it in to get fixed? as well approx. how much will it cost to replace <in C$>

its a 99 Grand Am GT 3.4L

Look under the Throttle Body. If its wet you have a leak. Yes it is serious so get it fixed ASAP. You dont want the coolant to get in your oil or visa versa. That will cause even more problems and money.
I paid $600 to get it fixed along with some other things i got taken care of. This price is low however becuase i know the guy who owns the shop and he helped me out. Most members report payin anywhere from $600-$900 to fix JUST the LIM gasket. I dnt know how to convert that to CN.

Is there a mean time between failures on these things? (i.e. lasts bout 25,000mi.)

aha. Found some numbers under the "Warranty, TSB and Recall Info" forum and in the "Why is the LIM problem not a recall?" thread.

So, GM says this problem is typically around 30,000mi. I see people have found it to occur between 10,000 and 50,000mi.

In otherwords...nobody is safe. ever. yay GM. Wonder how long until my 2003 pops its gasket...13,000mi and counting.

It didnt happen till 70k miles on mine. 600+ bucks later.......

Don't worry. Both of yours will go soon, gm makes sure of that. I replaced mine about 20000 miles or so ago, and it's back on the supposedly "redesigned" gasket.

My moms is lucky, 60k and no leak, clean oil, clean coolant, everything keeping its level.

It will happen to your moms eventually. I havent heard of the revised gasket going out also, most have had good luck with it including me. So far.

You could always call Pontiac like I did and complain about it being an expensive known failure, refer to the TSB, and tell them that you don't think it is right that other GM cars have this recalled but not the Grand Am. I got mine done for just over $400 by complaining.

I have "the leak" and when I refilled my coolant resivoir to go to school, I think the leak stopped. I dunno what that means...I was starting to look for places to get it done at.
