My cousin has a 99 pontiac montana with a bhg and while hes thinking of junking the van he came across a product called steelseal. similar to the other liquids you add to your cooling system to stop a bhg but this one was nice because they claim its 100% liquid (wont clog anything). have anyone of you guys tried it?
