>>>On a 91 2.1 which way is the thermostat housing bleeder screw closed?
Clockwise or CounterClockwise? I just replaced a hose and need to bleed
the system. I messed with the
valve and can't remeber which way it was.<<<

Clockwise is close, the bleeder screw won't come out completely, it as 2
small tab to keep this one from falling down. I found out that the bleeding
hole is sometime pertially clog, so for a better bleeding i removed the 2
tab and i completely remove the bleeding screw. Just a suggestion!
