My personal fan update.
Well you all knew I updated my fixed blade fan to a clutch fan set up and I was going to continue on to the electric fan update as well.
Things changed I was also looking to replace my rad too, its not leaking but the fins have all gone brittle and are starting to fall out of the core.
Well to re-core or replace with a new factory OEM style brass and copper rad I was looking at between $500 and $600 Canadian for a four core super cooling rad.
So I started investigating buying a full aluminum rad, prices varied from around $300 to over $1,200 and most were universal fit requiring modifications.
But as luck would have it I found through a friend a company called Griffin, they make a factory fit will work with my shroud all Aluminum rad for my 1979 Bronco, price is $646.00 Canadian delivered.
Also I will be sticking with the clutch fan because it moves more air than an electric fan and uses about the same amount of power and as a friend of mine pointed out all the big hwy trucks use clutch fans not electric.
I will be pulling a 4,500 lb travel trailer so I need all the cooling I can get.

Also you can get aluminum radiators on Ebay for about half the cost of Griffin.

Also, I think the 18 wheelers with the engine driven fan are operated by an "air clutch", and run very rarely. The fan is usually off.
I'm trying to duplicate this "fan off while on the highway" deal by using an electric fan.

A CAT C-15 diesel engine will cycle the fan on/ off at 215 and run it continuously at 235.
With the A/C on, the fan will begin running continuously at 185.
The fan is also regulated by what gear the truck is in.
The fan can also be turned on and off manually with a dash mounted switch.
It's a pain in the **** trying to troubleshoot the fan system on those engines, and our company has 8 TRUCKS with that engine!!!
