can either someone here give me a quick run down on a thourough cooling system flush or direct somewhere i can find these things out? My number 1 concern is burping the system for air once its all flushed and im trying to refill with coolant

If you want to burp it let it idle with cap off. once the air stops coming out and the coolant bottle starts filling back up from circulation, put the cap on.

One way to cheat is to loosen the top rad hose from the t-stat housing and fill the radiator that way. eliminates some but not all of the burping time.

ok, so when i was making my first attempt to flush the system, i accidentally let my coolant bottle cap fall off my valave cover while the motor was running and the cap hit the clutch fan. Now something up front squeeks loud as hell while its running...what happened?

You probably bent the fan blade, throwing it out of balance, thus causing the bearing to squeak. I wold suggest removing the belt and checking the shaft and pulley bearing.

anyway you can direct me somewhere that could potentially walk me thru that process? or if ANYone on here could point me in the right direction, that would be awesome!
