Patrick Martin - 100 operating temperature

Posted by Cedric on March 26, 2007 at 04:13:50 from (210.86.41.113):

During the Nebraska Test for the 100, the coolant temperatures recorded throughout the various tests ranged from 170° to 185°.
I have just recently done some major work to the engine of my '51 Super C and installed a new IH temperature indicator. Like yourself, I prefer to read "numbers" so that I know exactly what's going on, so before installing it and to get some idea of what the actual temperatures were at different positions of the needle on dial, I immersed the sensor bulb in a pan of water and slowly brought it to the boil. With an accurate thermometer I noted the position of the needle as the temperature increased, and at 170° it was pointing to the upright bar of the letter D of the word Cold. At 212° it was on the right side of the letter U of Run. At this temperature it should have been in the Red zone.
After getting the engine re-assembled and running I did a second test. With the engined warmed up I put the thermometer in the top of the radiator and the reading was similar - 170° with needle on the letter D.
Last week I drove the tractor 75 miles towing a trailer with my Little Genius plow on board and on a long fairly steep grade the engine was working pretty hard and the needle went to the dividing line between the Cold and Run zone which is approximately 180°.
If your gauge is only reading 100-120 I suspect that the thermostat is not working, the temperature should go up to at least 160° even on no load.
I'm far from satisfied with gauge on my tractor, and intend to find out what sort of warranty it has. It cost me a small fortune and one would expect the needle to be in the Hot zone when the engine is boiling it's head off. Sid.
