The pump im using is a billet MEZIERE electric water pump w/reserve. built in expansion tank, usuable as fill point and air separator, eliminating air locking/cavitation. Designed for the 3.8 and can handle up to 500hp. flow of 35 gpm. runs about $280-$290. i cant find any information on my rad though. But im running a 27" electric puller fan by Flex-a-lite. Twin 13 1/2" fans fulling 4600cfm with a max draw of 28 amp. Built in variable speed control with adjustable thermostat, a/c realy and manual switch connection. Came with universal mounting bracket and simple as hell. Though its over kill but perfect for advancement. Ran about $369. There are excelent selections from Flexalite if you want something smaller, and cheaper.
