You are out of luck man....It's not totally the Dex-cool's fault that your LIM gasket leaked. The major problem with Dex-cool was it sludging up and clogging stuff up in the system. It isn't good for as long as they say it is.. They made the LIM gasket out of plastic which was pretty dumb. Between the two you will get a leak at some point. They won't cover the repair, you've gotta do it yourself it really isn't all that bad though. All the replacements are metal now so you shouldn't see the problem again even if you stick with Dex.
