This fan for my Dodge truck was very hard to find. I came across etrailer.com and the picture and decription of it was what I needed. I got it very quickly and it was a perfect fit for my old fan clutch. It showed the right way the fan was suppose to turn. Installed it and now my truck is back on the road. Great fan and great price. I was very satisfied about the whole experience starting from the very nice sales lady that took my infomation.I would highly recommend etrailer.com to anyone looking for great products at great prices. 5 stars

Overall great product, this application was to replace the factory 19.25" fan one a Ford F-350 with the 7.5 liter gas engine, it required shifting the fan shroud over 1/4" to allow for blade clearance, pulls more air than the factory 5 blade did and does with with less noise and engine strain. highly recommend this unit as a replacement for OEM fans.

I had been searching for a 12 valve cummins replacement fan for a fee months and found this one noted on a forum. The stock fans are discontinued and junk yards around here want rediculous prices for them. With a little bit of die grinding (could have been done in a few minutes with a round file) it fit right over the dodge cummins clutch. Couldn't be happier. Fits perfect and saved me a large chunk of money. Thanks Derale for making a fan to fit.



by:

Had concerns about the smaller diameter. But have not had any cooling issues. Fit and clearances were good. Took forever to get it.



by:

Well constructed from heavy material. Much higher quality than the chinese crap i looked at in the auto parts store. As expected it is a little more noisy than the stock fan, but it provides a ton more air flow. So far om very happy with this product.



by:

Cools very well! Took a half round file to fit the hub to the fan clutch. Not noticeable loud.



by:

bought as a set with clutch hub , and was able to get my truck back on the road .
I am very pleased with the parts I received .

  • Recommendation for a 1997 Dodge Ram 3500 Diesel and Mounting a Derale 20 Rigid Belt Driven Fan
    According to my contacts at Derale the 20 inch Rigid Steel Blade Race Fan # D17320 can not be mounted to a fan clutch, it is considered a rigid mounting system. This fan is considered a standard rotation, has a maximum rpm rating for up to 8,000 rpm. However, if you would like to consider a fan that will mount to your fan clutch, then you would need the # D17120. This style of fan would mount to your existing fan clutch, and would not need a spacer for mounting. It is also a standard rotation...
