Fan from a salvage yard $25-40, mine is a Ford, take a tape measure they are used on all sorts of vehicles. Get the wiring harness as much as you can.
I bought a Hayden controller, $35 read the directions.
Overflow tank, Advance auto, ~$12-14
Windshield washer bottle K-Mart kitchen drink container + hose and 3/8" pipe fittings ~$20, to attach the stock pump to the same area. Did some fabrication and about 1/2 a day. Wiring up to the relay so it wouldn't through a code was the biggest problem, finally piggybacked the Hayden control on the relay in the fuse box.
