Bill and Brent, I still haven't installed the fan. I have ordered but not installed the flow restrictors ($6). Picturing the water flow plan I don't understand why there has to be the larger line from the radiator to the surge tank after all..... isn't the other end of the radiator already plumbed to the surge tank? Why not just eliminate that larger line altogether? The surge tank vents to an overflow tank anyhow... what function does that larger line serve? I've half a mind to just plug it at both ends and see what happens.... but then I've only got a half a mind when it comes to automotive engineering, that's prolly what got me into this spot in the first place

Truckin' along!
P.S. is it true that 220 is an okay operating temperature???
