Choose the largest diameter fan that will fit your car or truck. The Spal dual 11" fan assembly part number 30102052 shown here works great on vehicles with V8 engines and fits on most full size car and truck radiators.
Electric fans work the best when used in a "Pull" configuration. In other words, the fan would be mounted on the backside of the radiator facing the engine and pull air through the radiator.
This kit includes two 11" fans and shroud and draws 36 amps. It is 23-1/2" x 16-1/4" x 4-1/4" thick.
