Derale 17120 Heavy Duty Fan Blade Series 1000 20" Steel Clutch Fan Standard Rotation

Installed this fan on a Hayden fan clutch to replace (2) 12" Spal electric fans. Dropped temps at least 20 degrees. Excellent service and price, super fast delivery. Highly recommend!!!

When I bought an older used motor home, it had a flex-fan hard-mounted to the water pump pulley flange. It was LOUD! I knew that it was not the original setup, so I bought a fan clutch, and the 19" version of this fan. Moves plenty of air, increased the performance and fuel economy enough to be noticeable, and eliminated that awful windstorm sound coming from the doghouse! This steel fan appears to be of great quality. Already used over 9000 miles since mid-May. Road Trip!

It went right on with no problem

Love this cooling fan coupled to a severe duty fan clutch keeps my 1985 Flareside F-150 restomod with a SCJ 460 cool as a cucumber in the middle of blustery high summer temperatures with the AC going at Max, I ordered this fan as to ending up with 3/4" clearance from blade tip to shroud circumference which makes this setup super efficient as it is and the fan blades engage when it is only needed for fuel efficiency, great setup and great fan blades.

Well built and a great upgrade over my stock fan on a 1976 C10 pickup.

Good product,good price.

This fan is excellent! powder coated steel constructed and cools my old car down good five stars

moves a lot of air, too bad tips weren't bent
