860 always runs hot

Anyone have this problem?

Getting good flow of water as viewed through the top.

Have not checked actual temp, but I will. Note that when I stop, it often spits water out the overflow...I am assuming due to expansion and overheating?

Need to check timing and carb settings. Note also that I just rebuilt the carb and it has never run better! :o)

Thanks for all of the ideas, I will be following up on all of them!

Fan shroud, clogged cooling fins, too much antifreeze, bad stat, miscalibrated gauge. All set right you ought to be able to draw max power (plowing or chopping) @ 90ºF and not move the needle.

Let me state here that it is not good to run any vehicle without a stat. A thermostat keeps the engine running at a constant temp and actually slows down the flow of coolant so it does not zip through the radiator without enough time to release the heat it is carrying.

After I replaced the stat and fixed my loose rear wheel bearing, I immediately took it out into the bottoms and stuck it up to the axles. No, I did not do this on purpose. When I got stuck, I worked it back and forth trying to get out until I had it burried so deep I thought it might disappear altogether if it had not been for the vertical exhaust pipe. We then got monsoon weather and it was stuck out there for a month. It finally dried up and I got to drive it out two days ago.

After I got it out, I mowed with it and after an hour or so noticed that it was nearing the red on the temp guage. I cleaned the chaff off the radiator and it still seemed to want to stay at this level. The tractor never seemed to run hot, just the gauge indicated that it was, so I intend to take the temp with a thermometer and see where I am at. If it is running hot, I am thinking of installing a 6 bladed fan and this is where I could use some advice from any that have tried that.

I know that the pump has a good flow, and it takes a long time for it to reach these temps. Also I want to state that I have a trip bucket loader on mine and wonder if that might be enough to starve it of air. I keep the bucket at radiator height to push the weeds down and hopefully out of the radiator as it plugs up easily with weeds and other chaff.

I know this don't help you much, but I thought I would jump into the thread and add to it, hopefully to get some advice myself.

Had a 960 that ran hot, part of it was bad timing.

Also check the fad cooling fins are not clogged.

I have found my 861 will sometimes run hot after I have had the rad cap off, but it usually settles down after couple of minutes and never into the red.

Sometimes we overlook the simple.
