worked at the end of last season and isn't moving off of stop on low end. When I removed the thermostat to fill with AF in the fall I couldn't find a gasket so I "cut my own" out of felpro gasket material. <br /><br />Am I not getting a good ground? I think I remember something special about the gasket with a ground device.<br /><br />Thanks!<br /><br />2001 4.3L 210HP V6 TBI Alpha I Gen II
