This item DOES NOT include the radiator. This is a brand new SPAL replacement fan assembley with aluminum shroud for the Yamaha Rhino 450/660. This kit pulls 250cfm more than the stock fan, which is quite a bit and may be all you need to keep your machine cool on those hot days. The fan is water and dust proof with 6,000hr. brush life and a 3 year warranty. The aluminum shroud bolts right on to existing mounts using original hardware.This fan has higher amp draw because of the increased performance. This unit is only 1/4" thicker than the original. This is a 10" SPAL electric fan and pulls 800cfm at 9 amps. We waterjet these shrouds out of 5052 aluminum and they measure 14 3/4" wide, 10" tall not counting the mounting tabs and 2 7/8" thick.
