YM336 Running temp

[jsal007]

what is the average running temperature for a Ym336 tractor and what is overheating temp.

The Nebraska tractor test machine ran at about 155-160 degrees in general use, and never exceeded 180 degrees. Their air temperatures were around 75 degrees. Knowing that, if I were running a 336 and saw temperatures over 200 degrees, I would assume my cooling system was somehow compromised. As long as the coolant is not boiling over it's not overheated, but knowing how effective the cooling system on that model is supposed to be, I would start to inspect things were I to see temperatures above what they recorded. The highest temperature they recorded was for the tractor at PTO speed and loaded down as heavily as the engine would sustain, for two straight hours. This is more demanding than most people would ever be on their tractor, so is a good marker for maximum temperatures.

Thank you for info.

Unsure about the temperature but it is important to keep the radiator fins and screen free of debris, chaft, weed seeds, dandelion fluff etc. Mine would get warm when that occurred but as soon as that was cleared away it would cool right down.
