How to fix overheating in my TYM Tractor?

  Taylor KeyAug 8, 2025
  If your TYM Tractor is overheating, it could be due to several reasons. A common cause is a low coolant level, in which case you should replenish the coolant and inspect for water leaks. Other potential causes include a fatigued pressure valve spring (replace the radiator cap), a loose or broken fan belt (adjust or replace it), an oily fan belt (replace it), a poor thermostat (replace it), a poor water pump or water leaks (repair or replace), clogged water passages (clean the radiator and water passages), improper injection timing (adjust it), clogged air ways (clean the radiator exterior), or fuel gas entering the water jacket due to a broken cylinder gasket (inspect the cylinder head and replace the cylinder gasket).
