I bought my girlfriend a nice 98 bravada with 97k miles for 3k. If you fill up the gas tank the gauge reads normal untill 1/2 tank. Then it starts going E-F rapidly and gets worse the more you drive. Then stops when you fill it up. Then just today the heat was going in and out. It also smells like coolant. I put it in the garage and reved it up a few times to wish-fully clean it out. It started smoking under the hood and the smell of coolant was evident. Didint get a close look at it because it was dark.
I have no clue whats going on with the gas guage. Blazers, jimmys, and bravadas have vacum line problems. Could the heat be part of that? It stills has dex-col in it so I believe the intake gasket is done for. Could that be the coolant smell?
Please provide info on whats going on, thanks.
