Fan Clutch by Imperial - Part 216001 - Advance Auto Parts
Advance Auto
I am really considering a Horton electric fan clutch.
Horton EC 450 does have a model that will bolt to the IDI engine.
But the 800 dollar price tag is a little steep.

Most big trucks areequipped with hortons air not electric but horton is pretty much the industry standard.
In my experience about every 5 to 600,000 they need rebuilt but you just buy a kit not a new unit.
So if a guy is working his rig hard a lot of the time the cost could maybe be justified.

That's my point, it works on the same principle and design of an A/C clutch but is no where near the price. I could see maybe $300 but not 8.

But one big difference.
When you turn the AC clutch off, nothing turns.
On the fan clutch, the pulley still has to drive the water pump and release the fan blades only.
I already considered trying to adapt an AC clutch before I learned about the Horton setup.

I dont know about the idi horton but I suspect it is a lot larger, heavier duty and rebuildable, than an ac unit. One would definately have some advantages over our stock setup, it could be tied in to the ac so when the head pressure got high at low speeds or at an idle it would come on and a manual switch would be great, also would be a little less load on the engine when it was not on. Me thinks I would like one now why did you mention it.

Actually I was on a Power Stroke site when I saw the clutch write up.
He listed a switch off of a car that would screw into the high pressure line on the AC to lock the clutch and a temperature sensor for the engine that made that automatic control as well.
How I looked at it was all the advantages of removing the stock fan and installing electric replacements without the huge electric draw they make on the electric system.
If someone did the electric fan conversion using new fans, my bet is the cost would be about the same.
On a stock truck, the alternator would have to be upgraded with electric fans on trucks older than 92.
Now where is my Horton arangement number that fits the IDI engine?
Some information about the Horton EC 450, but nothing about the arangement numbers.

The Horton really is a great way to go. For most people, pickups in stock form is fine. For others almost nothing stock is fine. Here's a couple of trucks that look pretty good to me.

I was running 80mph for a while and watched it go up. At a point my dummy light came on "engine Temp". So I slowed down and let it cool down. It was a very warm day, and this was before I had put on the new injector pump and lift pump. Is there a way to rebuild my clutch fan or just have to purchase a new one?
DANGER DANGER . I think you would be surprised if you had an exhaust temp gauge to measure the EX temp.

I have noticed high speed driving does change the air flow through the radiator on my 86.
Not sure if it is the 4x4 or the snow plow bracket, but engine temp does go up at higher speeds or the other place I am thinking is the engine oil cooler.
The pyrometer don't really change that much as I go faster, but oil temp does start to increase after a little while.
Since the coolant goes through the oil cooler before it goes through the engine, it is adding a lot of heat to the coolant before it ever starts taking heat out of the block.
