I have not been worrying about cooling since it is winter time here and I do not drive my truck when there is salt present on the road. But now it is getting close to spring I got to thinking about how hot my truck runs when pulling anything. I know the cooling systems and fans have been beat to death on here but I ran across something that should work. I found a couple fan blades on the Horton website. 994559507 is a 22" fan 2.45 pitch 12 blade with a CW rotation. 995550502 21.65" fan 3.62 pitch 9 blade CW rotation and a 993584503 & 993584501 22.99" fan 3.65 pitch 8 blade. will have to do some measuring on front and back spacing but one of these should work and are available. I did find a couple 23.62" blades that may also fit. All these blades listed are nylon and lighter than stock. The only thing with trying one of these fans is will the viscus fan clutch slip, or lock since they should move more air. So I got to looking again and found that the DT466 in certain years ran an electric 12v fan hub, same thread pitch 1.25-16 UNF 28 LH as our IDIs use. There are also several options will have to get more specs on them. Horton part numbers 996127 is available on eBay right now for $650. other options maybe 996135, 996140, 996135. There is also a 996042 that has a flange style mount, possibly able to retrofit this to where the fan belt pulley mounts to the water pump. anyone ever look into these options? I did email Horton on the listed items and they are available.
