  If your wsm Tractor engine is overheating, possible causes include insufficient engine oil, requiring you to replenish it. The fan belt might be broken or improperly tensioned, so replace or adjust it. Check for insufficient coolant and replenish if needed. The radiator net and fin could be clogged with dust, requiring cleaning. The inside of the radiator or coolant flow route might be corroded, so clean or replace them. Other potential causes include a defective radiator cap or damaged radiator hose, so replace them accordingly. Overload running can also cause overheating, so loosen the load. Additionally, a defective head gasket, incorrect injection timing, or unsuitable fuel could be the issue, requiring replacement, adjustment, or using the specified fuel.

A worn piston ring groove could also be the issue, requiring you to replace the piston. Alternatively, the valve stem and valve guide might be worn, so replace them. Finally, oil could be leaking due to defective seals or packing, so replace those as well.
