I am installing a Horton Fan Clutch on my OBS. Here we go…
Someone suggested I check out Horton for my cooling needs. I did and I found out one of my friends could hook me up with a good deal on a brand new one. This one is made for the T444e’s and the DT466 engine family. Getting it on my truck and working “should” not be that that much of an issue. The unit is completely self contained. I do not have to splice into my factory harness at all. So, now comes the questions. My stock heavy metal fan fits it perfectly. But I prefer to use a later model plastic fan blade. I know the 99 and up came with plastic fans. But from what I have learned so far the fans that came on the six liters and up were massive. They are without a doubt much larger than the stock fan on my OBS. One thing I need to know about them though. Are they reversible? Can I remove the fan blade and flip it on the fan clutch? Also, when I replaced my fan clutch some time back I found out that the fans on some of 7.3‘s spin in different directions. Which years spin which ways? I will be rerouting my belt any way because I plan to do away with my mechanical vacuum pump and I also plan to replace my water pump. So I would think getting my fan to spin the direction required by the new fan clutch should be simple.
