I agree, Dex-Crap, oops, I mean Dex-cool turns brown and sludgy when it gets old or contaminated with green anti-freeze. Sounds to me like someone added green coolant to your car and mucked up the system. Do yourself a favor and flush the system of Dex-crap, (dang it, did it again) Dex-cool and replace it with green. I agree with 86TATpi that the gas guage problem doesn't sound like something you want to tackle yourself, let someone with wiring expertise get the headaches.
