What is proper Operating Temperature

[jenkinsph]

If you look at Nebraska tests on this tractor it will provide you with a range of temperatures under various loads. The highest full load test at pto speed for two hours shows 213 F. Light loads, idle and similar was 160F.

Temperatures of 180F to 206F should be in the normal operating range.

I did not see any crude come out with the flush. Followed with two water flushes and they looked clean also. Have read about the infrared thermometer and will probably get one. Have thought there may be plugs in the rdiator that a boil out might cure. Problem with infrared, it will show me hot and cold spots, but not the temp at which I should be alarmed. If red light comes on at 230 when water returns to radiator (using a John Deere probe), how do I calibrate to an infrared thermometer which is looking at the surface of thermostat.

Under full load at full power you may reach as high as 215F but should not reach 230F that is way to hot. A normal range depending on loading should fall between 175F and 205F approximately. You have to work the tractor pretty hard to get to the 205F and most work you would do should be closer to 175F to 200F.

Thanks so much, Mr Jenkins. I ordered the Easy Flush from HD and sprayed the radiator. It was so easy, I did it twice. Today I bushhogged for 1 1/2 hours in the 4th fear and temp settled out at 195. Many, many thanks.
