So,

Here it is 3am and I'm doing my "can't sleep" thing again; keep thinking 'bout Gary's 1066 tractor picture and my mind wanders to this darned old 966 of mine.

Okay, it runs warm when worked hard. Not hot mind you, but close enough to concern me and I keep an eye on it. Has a new engine, new water pump and the radiator is clean as a whistle.

Thing is, it only has a four-bladed fan. Has anyone ever heard of a 966 with a 4-blade? Think my old 766 was this way, but it wasn't near the horse that a 966 is neither.

Dunno,

Allan

I have nothing better to do so I was reading all these posts.

Do you remember those old Chevys with the 4 bladed fan ? Well it turns out a local dirt track racer/engine builder loves these 4 bladed fans says they cool the best ! We can even still get them new from GM. So yours just may be fine as is.

I stole Mom's oven meat temp gage it works great to test a radiator since it has that long probe on it.

When I was a kid I rebuilt an old Ford. Being on a tight budget I reused the old radiator hoses, which looked good. However, when she warmed up she would suck the top hose, which turned out to be a little spongy, partially closed and overheat. I replaced the top hose and the problem went away.

On a similar subject, I once chased an electrical charging problem by replacing the alternator, battery and cables to no avail before an old timer suggested I replace the fan belt, which looked just fine. I did and it fixed it. Reason: the old belt would stretch out when it got warm and allow it to slip just enough not to fully drive the alternator.
So, beware the old rubber components.

I had the same problem with my new Ford 5000 (it was dynoed at over 80hp). Eventually, we added a larger fan from a 7000 and problem was over. Tractor has over 10,000 hrs on her now and motor never touched.

Agree with the post about checking sending unit and gauge. Also, I'm sure you put the thermostat in that the specs called for. Any chance that a cooler thermostat will help? Also, does it heat up when used hard in cool weather or is this just a Summer problem? If it just heats up in hot weather changing the fan take care of things.

Dunno,

The darned thing just seems so "right" because it takes about four hours of heavy pulling in 100 degree temps to make it go over to the hot.

However, I did notice that it also takes it a heck of a long time to cool back down after the load is removed.

Maybe it is that darned guage. Guess every temp problem I've ever had with an IH has always came back to the indicator. :>)

allan my bs 966 has a 4 blade fan and we have no heat problem with it, 18 ft 470 ih disc , or 20 ft harrowgater, it will make it rough on a 1066 in a days time, if you can see thru your rad, check your thermastat, it could b stuck a little bit open or not b there at all. either way would cause it to heat up over time, no restriction is as bad as to much

It is all brand spankin' new except the gauge. Just didn't know that they put four bladed fans on 966s. Never gave it a thought before, I guess.

This is all Gary's fault anyway. :>)

allen i lied to ya, my 766 has a 4 blade fan my 966 has the 6 blade just like my 1066 has, funny how you miss these little things, i bought this tractor from a local ih dealer 5 years ago, it is a black stripe had the narrow and wide front also had the air cond cab , mayby thats why its got the big fan, the ta was toast when i bought it, we made it a fender tractor, absolutley love it, nice to round bale with the narrow front sure makes big windrows cooperate a lot better

Allan, Morn'in! Just came back through, to do some paperwork and check the Boards. Anyway saw your post on here on 4-bladed fans. Went out and looked at my ol girl, She has a 4 bladed fan. You know how hot we get down here in Central Texas in Aug/Sept...100+. Mine has never offered to get hot, unless it has been low on coolant!
I an sure yours isn't low on coolant, and everything else is either redone,reworked, or repaired to better than new specs. Sooooo..... ...could that new thermostat be sticking?? or stuck partially open, so that it wouldn't be noticeable till your are in a heavy pulling situation. It shouldn't but it could. Based on my mediun summer air temp,Tractor full of coolant,that is my guess. You shouldn't need to change out the fan.
Or your old girl is turned up at the pump something fierce, and you are making more HP that the radiator can handle in that situation.
Just some thoughts, I look forward to what the solution is!
Later,
John A.

Hey Allan,,,Well lets see here--could it be that the anti freeze has been neglected over time and you have a major sludge build up in yous block around your wet sleeves.....Id definitely try the 8 blade fan and all the other easy ones first

Don't know your answer, but when I bought the 4166 it had an eight blade fan. Never got above low mid-temp in hot weather when using the A/C. The parts book shows a six blade fan, which I got from a salvage yard for around $80. This "new" fan is now installed and will be tested this spring.

Forgot to mention that they also upgraded to a double belt fan drive. I didn't change back to the single from the two drive belt arrangement when the 6 blade fan was installed.

Good morning Allan

It looks as if all the bases have been covered on this running a little warm situation. You have probably check the cap to be sure it is holding good pressure. I would just put a new one on to be sure.

IN case you have a way to check the temperature of the top tank versus the bottom tank, the temp should drop around 10 degrees. If you have a substantial difference it would indicate there is not enough flow thru the flues. Someone before you might have closed off too many in the past to cure a leaking problem.

You will probably lower the running temp with the fan change, but just in case

Allan, you know I do not do much with heavy iron...biggest thing I have is that 656, but are you sure that sender and gauge are right?
I just went thru that on a green 720D. All it turned out to be was a bad gauge. I replaced the whole works.
Just my 2 cents.

Ever think of dropping a 12 Volt fan in front of radiator one like on newer cars you could even install heat senser to turn on & off . Some times they just run hot and it don't hurt them If a car or truck ran at the temp they do now in the 50's "180 verses 220" we would have parked them . The flat head ford V8 ran hot if you ran it over 55 MPH for extened period of time in hot weather . was the nature of the beast .

8 blades sure wouldn't hurt anything would it?

I know where there is one if a 986 would be the same.

I Know they'll say different but!! there also a 1.in smaller upper pully you can use make that fan just a little faster

Mornin' Allan.

What a cold, dark way to spend a morning! But at least its for a good cause...

You could try some of that "Water Wetter" stuff that they make for antifreeze. Its made by a company called Red Line, and they have pretty good products for the most part. They even have a diesel version!

Link

I dont know if it will fix things, but it might be easier than trying to swap that fan...

Oh heck,

I can swap that fan in about 2 minutes. Just have this funny feeling that this thing got traded out somewhere along the line for the cheaper version fan.

This tractor was a salvage "throw-away" black stripe when I got it and had really seen better days.

The way it heats, it just acts like it isn't getting enough air too. Darned heat gauge runs right up "just off" the hot mark on a real hot day.

After working on Gary's 1066 and noticing his 8 bladed fan, I just think something is arye here. :>(

I dunno Allan...

How cold is it outside your house right now?

But then again, I guess it figures that the same guy that wants to fix his air conditioning in the winter is worried about his tractor running too warm this time of year... *grin*

If you can get one of those fans cheap, then why not swap it? But you know that one project will lead to another one, and another one....

Not that its a problem, that just tends to get expensive eventually :)

Since no I has asked this question, here goes:
How long has it been since the radiator has been cleaned out, boiled and rodded???

While everyone is guessing, my guess is the sender overloading when it gets hot over a period of time. Good luck..... ....
