kramttocs Posted April 24, 2023 Share Posted April 24, 2023 First off, thank you all for not turning this into a debate over electrical vs. mechanical fans. If one were to use a single fan, like the 16" Taurus, could it simply be mounted off center to allow clearance for the water pump pulley or is that unrealistic? Again, assuming I'm making my own shroud. Anyone ever heard of that working? For your homemade shroud are you going to mold it or in some way funnel it towards the off center fan? I don't think I'd want to do a single off center fan with a flat shroud. Link to comment Share on other sites More sharing options...

My thought was to take a piece of sheet metal to cover the remainder of the radiator, but cut some sections on the passenger side with vertical slots and cover them with rubber flaps so when the fan is running at a stop or low speed, they will be closed, but a higher speeds will open to allow more air flow through.

I know this is a 79 truck and radiator but it is 400 powered. I was able to score 2014+ Cherokee fans (7 and 9 blade) for free. They just about bolt in this truck and I think they'd easily fit an 80+. I wired it in myself after removing the driver module to dual relays and a thermostatic switch.

Pete Whitstone Posted April 25, 2023 Share Posted April 25, 2023 I'm going to tag Scott/kramttocs as he's played with electric fans on his 460 - and has had some problems. But so far I'm sticking with the mechanical fan so don't have any experience to add. I'm not sure if the 460 and 351 radiators are the same, I think they are. I went with Infiniti fans when I converted my truck, they were pretty inexpensive but have held up really well, and work well. I documented that swap here. https://forum.garysgaragemahal.com/My-81-flareside-is-going-electric-td60503.html Link to comment Share on other sites More sharing options...

I documented that swap here. https://forum.garysgaragemahal.com/My-81-flareside-is-going-electric-td60503.html On the Bullnose there are three sizes and two different styles. The Diesels are all by themselves due to the size. Gas engines have an early and late mounting style, late carried through from, 1984 I believe until 1996/7. There is one radiator size for a 6 cyl and one for all V8s, 302-460, not one of Ford's "better ideas". Reason is probably due to Ford dropping the 460 at the end of the 1979 production and then having to scramble in 1983 when it was brought back. since there is about 7" between the end of the water pump shaft and the radiator core, things are tight.

Can someone please explain to me what the Super Cooling option was with these trucks? Link to comment Share on other sites More sharing options...
85lebaront2 Posted April 26, 2023 Share Posted April 26, 2023 Can someone please explain to me what the Super Cooling option was with these trucks? Jim, according to what I found on Darth's Marti report, it is an auxiliary transmission cooler. That wouldn't apply to Lil'Red unless he started as an automatic.

The Marti for my 92 Bronco says, Trailer Towing Package, Heavy Duty Service Package and Super Engine Cooling. And lot's of other options, this Bronco is loaded. That's what's really nice about getting a Marti report. Link to comment Share on other sites More sharing options...

Again, assuming I'm making my own shroud. Anyone ever heard of that working? Isn't your engine already offset? Or is that only with the small blocks? The small blocks are offset in the trucks about 2" to the passenger side. My current truck is not a Bullnose, but I am running a Champion aluminum rad and 16" Spal low profile fan. It is dead center in the rad which is centered in the truck, but my engine is offset almost 2" to the passenger side. If my fan and water pump pulley lined up perfectly I'd only have maybe 1/4" room, but since they're offset from each other it feels like I have more room than I do.

The 460s are offset to the right, probably the same 2". Link to comment Share on other sites More sharing options...
