Yanmar Tractor Is Over Heating
My Yanmar Tractor Is Over Heating...... What Do I Do?
Difficulty - Easy
The Yanmar tractor cooling system is very simple but can still develop overheating problems. A little investigation & prevention can save you a lot of time and money.
If you have a YM135, YM155, YM165, YM1100, YM1300, YM1500, YM1600, or YM1700 be sure that you are using NO MORE than a % 25% antifreeze mixture in the summer (add more in the winter). These models use a very effective ThermoSiphon system and do not have a water pump. They use the natural tendency of hot water to rise to circulate the water. Too much antifreeze will not circulate correctly and does not conduct heat as efficiently. It sounds funny but Please Believe Us.... We get at least 2 or 3 of these calls per day! Dilute your mixture to 25% or less in the summer if your tractor does not have a water pump. Don't forget to add more antifreeze in the winter to avoid freezing.
If you are unsure about any of these steps- please ask a qualified mechanic for help! |
