Does anyone know the factory thermostat temp for the 4110. Would putting a lower temp in help with cooling the engine?

Not sure what the opening temp is on the 4110, but you shouldn't be having any problems with the one that's in it, unless its a bad one....lowering the temp on a thermostat will help in holding down the engine temps, however, that's not necessarilly a good thing in a diesel, or a gas engine for that matter. Pretty much all good tractor radiators are overkill for normall applications. You want the temp to be "halfway" up in the "green" for good combustion and alleviating any condensation that may build up on the INSIDE of your engine (which then ends up in your crankcase). You want the engine to get hot enough to burn off that water...PS: before you change out your thermostat (assuming its running hot), put a thermometer in the radiator and see what the temp of the anti-freeze is....you may have a bad guage.

I'm pretty sure that it isn't the guage, this is a problem that I have fought pretty much from purchase, I have spoken with the dealer several times and even posted here about the overheating problems. I have blown the radiator from back to front, taken off the side covers for added air flow and keep the air filter clean and so far the best I can keep the temp it just below 3/4. If I work it very hard(Bush-hogging and such),30-45 minutes is all I can get without cooling it off. It is a 2004 model with less than 300 hours. I will,try the thermometer though, thanks.

I imagine you've already checked but it could be simply a belt a little too loose and letting the water pump slip ever so slightly at higher rpms. I don't know what the opening temp. is but BobG is giving sound advice about not lowering the thermo. opening temp. My 4110 will run high on the gauge when cutting grass on a hot day and the radiator gets just a little chaff in it. I have seen it right at 7/8 the way to hot and have run it a little while at that temp. - has never lost any coolant (boiling over) from this. All I have to do is blow the radiator out good with 100 psi air and it will run at normal again, which on my gauge has always been between 1/3 to 1/2 on the gauge. When I blow the radiator out, I start blowing from the rear to the front but will also blow forward to rear and alternate this a couple times - I get lots of chaff out going both ways. What really cleans it good is taking the battery out and using my pressure washer on it both ways - I do this at least twice a year. If you have an accurate contact thermometer or infrared thermometer you can check the operating temp either at the thermo. housing on the engine (the hottest spot) or the upper radiator hose and not have to have the cap off.

Thermostat, slipping belt, air flow and gauge is working has all been checked. How about water pump? Could an impeller or what ever it's called be defective? I wonder if it's possible to check flow on pump? I don't remember what the side covers do, but maybe it's better for air flow if they are on. Maybe something is in engine obstructing flow. A piece of hose or some othe part. Stranger things have happened.

my 4110 plugs the rad very easy. when pluged runs three fouths on gauge.
not to beat a dead dog, have you used a light to look through the rad from the back .i had to remove the rad fan and right rad mounting brackets. to clean correct.

It could be as simple as being a bad thermostat and it isn't opening all the way to allow enough water flow.
I had the same problem with my 4110. Ended up being the radiator was plugged up, I must of gotten a LB of seed, dirt, mud etc out of it. After checking the normals suspects, I ended up pulling the radiator out to do a thorough cleaning as I couldn't get it clean enough with it still mounted in the tractor. Removal of the radiator took me about 15 minutes and I think I did a much better job.
I now run about halfway up the gauge on hot days when swinging a 6ft bushhog whereas I use to worry that I would get near overheating. With what I went through (checking thermostats, replacing antifreeze, trying to clean radiator in tractor) I would suggest just getting ready and pulling it out. I think you'll be surprised how much of the radiator is plugged up.
And I can help but say it

I was cutting some high grass with all that seeds, dust or whatever it's called and sure enough the rad plugged fast. Cleaned it out and decided to wait for a morning with lots of dew on weeds. Right after a rain would work good too. Anyhow, that solved my problem.

I spent a lot of time and thoroughly cleaned the radiator, I used a can of air conditioner coil cleaner followed with the pressure washer and then used the air compressor to get it good and clean. Looks really good and then I started my pre-use inspection and found that the tractor is leaking fluid from around the rear pto shaft. I cleaned the area up and left it for about 30 minutes and came back and sure enough, more fluid. That's without cranking the tractor, the fluid level is still ok so it must have just started, any suggestions as to what this may be, seal maybe, something more.
