Which coolant for LS1?

My 97Lt1 came with Dex Cool and yet I'm still hearing opinions that it is "bad".
Nevertheless, I don't intend to switch until it is proven to be "bad".

So what coolant came with the LS1s and did it come with all of them?

Just trying to get an idea of why (if it happens to be the case) that the Lt1 would come with Dex and the LS1 would come with something else.

Thanks.

all 96+ GMs came with dex cool. Keep it maintained and there won't be problems with it. I wouldn't recommend going 150k or 5 years like they say...i'd do 60k 2 years.

Just change it every year with a powerflush and you'll be fine. That'll wash out any junk that has built up in the system.
