Default ? help on 3800 UIM , Dan or Bill ?

Ok I sked this question before but no answer:
I bought a 2000 Lesabre Limited with 25k miles and it is mint...Under is as clean as a 2011 car. Heres my ? With 25 k on it ho long before I can expect UIM problems ? And should I change/plug it now or will it probably last a while ?? I think my Park Ave one failed after 120k Whacha think

You should be fine for a while. But it'* hard to say when it will fail. If it was me I would simply pull the UIM and plug the ports, but that'* me and I can do it with my eye closed.

You should be good to 100k. If you don't know how old the coolant is, then change it out. You can refill with Dex or any color, your choice.

If it'* over 5 years old, change it regardless of miles.

If it looks clean, it may have been changed. But I'm a believer in, if I don't know, I change it. New coolant is cheep.
