    This was on '72 T'all, I'd guess your space situation is different than mine was....I just didn't have enough space between the front of the engine and the radiator to make it happen, so I went to a spacer & flex. Did I have the correct clutch at the time, 15 months ago?? Who knows??? I looked at one @Napa two weeks ago, when I was putting the motor back together, and decided it wasn't correct, didn't fork over the $60 to take it home and try it out for certain...

    Well it's been two years but I did get mine at NAPA.

    If that source is no longer available I bet Super Scout Specialists or Back Country Binders have them. It's just to important an item when your talking AZ and CA desert. Mine works great, mostly free wheel on the freeway while pulling the trailer in 100 degree heat but when you start to pull a hill you can here it kick on and it keeps the temp down. Or while in traffic with the A/C on it will kick in and pull a lot more air. I sure wouldn't be without it down there. I used to live between you two guys in Yuma AZ.

    I wonder if there are different water pumps causing this?
    I'll try to get a picture of mine up tomorrow...

    Good luck getting the electric to cool enough....we were out wheeling all weekend and the only guy overheating was the Scout with two electric fans...

    I had trouble finding a thermal clutch to replace mine, ended up going to a flex fan because the thermal clutch had too much depth, I didn't have enough space...

    The fan spacer was probably different.

    With the spacer the fan mounts on the front of the spacer.
    With the fan clutch it mounts father back and the thermal part is in front of the fan.

    If your all stock it should fit... only variable would be the diesel shroud.

    Electric fans are great but will the one you get have enough CFM ?

    I picked up the steel shroud to replace a plastic one that had been cut to clear the mild body lift of poly mounts. The diesel shroud bolts right to the original mounting holes for the plastic one. The shroud fit just fine. It was the electric fan that was too thick.

    When I was looking at the fan clutches I didn't have the exact measurements since the radiator was still at the shop and not in the Scout. I didn't find one that was the same depth as the fan spacer.

    Well if your running a Scout radiator with the metal diesel shroud, what motor do you have?
    Why won't it fit? Maybe the IH fan clutch is differant?

    Back to the drawing board

    While I was waiting for the shop finish my radiator I stopped by the parts store. On a hunch that maybe most fan clutches are pretty universal, I had the clerk pull out a bunch of them. After deciding that they were all too thick, I left with a 16 inch electric fan and a thermostat fan control.

    My youngest son bead blasted the steel fan shroud (from a diesel Scout) I got from Travis and after some flat black paint and minor fabrication, we mounted the electric fan to the shroud (which has a 17 inch opening) and bolted the whole setup to the radiator. It looked really nice.

    When we went to drop the unit into the Scout, it wouldn't clear the pulley. We lacked about an inch. Since I need my Scout to get to work tomorrow, we put it back together with the stock fan.

    However, the smaller diameter electric fans are not as deep. Now I just need to find a piece of sheet metal to cover the back of the steel fan shroud. Then, I'll cut smaller holes and run two smaller diameter electric fans.

    Where there's a will, there's a way.

    If your'e not worried about retaining the stock look another possible way to go is an electric fan conversion. I'm not sure about the cost but I have had friends do it on their non-binders.

    That sounds like mine. Non threaded.
    Scouts came with clutch fan chances are yours did and when it went bad someone replaced it with a spacer.
    I think the fan itself is different too on the clutch, you need an original. Check and see.

    It's just 4 bolts that go through the spacer. There's about a 1/2 inch diameter shaft sticking out of the pulley but it only sticks out about 1/4 inch and it's not threaded. My biggest concern is how the clutch would mount and how thick it would be. I wasn't able to find photos of the different clutches. It's a special order item so it's not like I can just go to the parts store and look at one before I order it.

    Thanks for narrowing down the list. For the extra cooling and power gain, I'm tempted to just spring for the $32 and order the thing. Lord knows I've spent more $$ than that in search of horsepower in the past.

    Thermal is the way to go. When it reaches a certain tempreture it will lock up and draw more air. Before that it is just free wheeling.
    The non thermal does just that free wheel.

    The differance between thread on and standard is the way they mount. What do you have? Like four bolts or a big thread on thing?

    Which fan clutch?

    I read an article, on line, that mentioned that adding a fan clutch as opposed to running a spacer gives you a 5 horsepower gain. Since my radiator is out for a rod and core I thought I'd add the fan clutch. A quick check with Checker (on line) reveals 4 different models. My question is which one to use. I'm running a 304 of unknown vintage. The fan looks like a stock item with about a 1 1/2 inch spacer on it.

    Any ideas???

    Imperial 211049
    Fan Clutch: Non-Thermal; Standard Rotation; Except Thread On Fan Clutch

    Imperial 215049
    Fan Clutch: 7" Thermal Regular Duty; Standard Rotation; Except Thread On Fan Clutch

    Evap Inc. 4949
    Fan Clutch: Non Thermal; exc. Thread On Fan Clutch; Rotation = STD

    Evap Inc. 4849
    Fan Clutch: Standard Thermal; exc. Thread On Fan Clutch; Rotation = STD
    :confused: :confused: :confused:
Working...
