I am working with a 2006 diesel tractor with 400 hrs (100 hp)that runs hot(230*f).How big of a temp difference should there be from top of radiator to bottom?The fan is direct drive .Thank you
I wouldn't think their would much of a difference. What type of tractor is it? We had a little challenger MT545 that ran hot to. It was caused by the designers putting too many radiators in front of each other. Needless to say, it's gone now.

There will be a big differece. That is how the radiator works.
Hot water in the top, cold water out the bottom.
230 going in seems high. Is there a stat? Try taking it out and running it.

isn't it the other way around?...i may be wrong but i thought the coolant flow was bottom to top ?

There isn't any reason it can't be that way but that is generally used on exotic high performance cars.
There should be a large temperature drop across the radiator, you should be able to feel it with your hand in the air if it is a pusher fan. If it's a puller fan you should be able to feel it on the surfaces, don't get burned. If the lower tank is too hot the radiator could be clogged either on the water side or by dirt and chaff, or it could be the incorrect radiator...had that happen to me with a new genset, took forever for them to figure it out and replace the radiator under warranty for a one that flowed less water but then it worked perfectly.

ROT: [rule of thumb], 15*F difference between top-bottom. make sure that there is no opstruction in cooling fins. Use a low pressure hose to flush the outside of the core[s]. Useage of a high pressure hose can bend the cooling fins over. Drain the coolant. replace it with 50/50 mix, while it is drained look inside the radiator core from the top if possible. You are looking at the cooling openings inside the radiator. They are to be CLEAN, and NO BUILDUP of SCALE. Useage of higher than 60/40 solution will cause the cooling system to overheat, likewise less misture will cause rust and faster overheating and of course poor freeze protection. Replace the thermostat while you have the coolant drained.

It is said if you sit by the river and watch the water flow by long enough, your enemies will pass by. This I believe to be true. It is also possible to watch your loved ones pass by as well.

100% water provides better heat transfer than a water/glycol solution; a more-dilute mixture will not cause faster overheating. Water has better thermal properties than glycol solutions, and is less viscous so the same water pump provides a higher flowrate.
Using a stronger glycol solution will not, by itself, cause it to overheat. If you're right on the verge of overheating anyway, using a stronger solution might raise the temperature several degrees.
In Modesto, California, you could use a 25% antifreeze mix for corrosion protection and ignore freeze protection.
Don't replace the thermostat just because you have the coolant drained. Replace it if it's broken, and it's probably not broken if your engine runs at a steady temperature.
A year-old engine isn't going to have a scale buildup problem unless there was something seriously wrong with the water chemistry when the factory mixed its antifreeze.
I don't think 230 degrees F is any cause for concern. Have you checked the temperature gauge calibration?

I assume that this is a pressurized system? If it is, and it is building pressure, each pound of pressure should raise the boiling point approximately 3°. Therefore, a 15# pressure cap would raise the boiling point by approx. 45° giving you a safe margain of error at 230°. If the tractor is overheating, have you pressure-tested the system and the cap? Also, modern engines run hotter than 212° so they generally do not have numbers on the temp gauges because the average "joe" knows that water boils at 212° but might panic if he/she sees higher temps on the gauge.

Thanks for the imput,I think its been solved by changing the ac condenser to a more open flowing one,and removing the underhood muffler and strait piping it.It is only slightly louder(turbo charged).now it seems to not exceed 220* on the dyno at 100% power for 3 hrs.The tractor is basically new so there is no scale or plugging anyware.My engine oil sump was running at 275* now its more like 240-250*.There is no way to work the tractor this hard in field conditions, so I think I have it!

Hank knows what he is talking about, Doug, and he is right on this one. Of course in Modesto you could run straight water with corrosion inhibitor so long as you had enough pressure to deal with the boiling point. But running extra glycol can cause problems in cases where cooling is already marginal such as a narrow nose T600 with dirt in the fins pulling 100k uphill at 23 mph for half an hour. It might be right on the verge of overheating and any further strike against it could put it over the edge. You just have to cover all your bases
There was a guy from an impliment company who had a 6V-53 in a trencher. He was told by his supervisor to put in 100% ethelyne glycol and send the machine to St George. He spend big bucks trying to cool down the machine. He finally came into our shop and I questioned him on his application. He was told by us to drain all the antifreeze. Replace it with a 50/50 mix. He had no further problems with the application in that area. Likewise a misture of 100% antifreeze will freeze faster than a 50/50 mix. Last time I checked the comtainers of antifreeze bought at the local autoparts store will not recommend any mix than 60/40. We say 50/50 because there is less error to the layman just in case someone miscounts on the install of the mix. I am not a sceintist, just a mechanic who has seen both of these problems in the field.
No problem and no offense ment. Just my personal knowledge in the field.
