Any size radiator will work if you pull enough air over the coils. My big motor over heated until i got a fan from a Lincoln Mark VIII. it comes with a shroud and pulls major amps so expect to upgrade your alternator to 100 amp. I tried Water Wetter and every other gimmick including 2 other fan setups until I got the Lincoln fan. I have cruised it in D.C. in 100 degree weather with no problems. When the fan kicks on, it drops the temp like a hammer. One issue though...keep anyone under 60 pounds away from the opening for the radiator!!!!
