A guide to servicing your tractor's cooling system

It's about to be the first of the month – time to check your tractor's coolant. If your antifreeze looks old, odd or does not provide the range or protection required to properly run your tractor, it is a good time to change it.

Most tractors have automotive-type drain valves, one on the bottom of the radiator and another on the block. The valves have a wing on two sides in order to allow you to loosen the drain using only a pair of pliers. The problem lies in the fact that these drain valves are often inconveniently placed, such as under the front grill or beside the starter motor, which can make it harder to wiggle in a pair of pliers to open or close them. Force may be applied in such a way that the wing may break off or break the valve entirely. The best solution is to get an old socket large enough to overlay the shaft or barrel of the drain valve.

How to service your cooling system

  • Check radiator cap for proper installation, chips or rips.
  • Clean mesh screen.
  • Test radiator hoses for softness.
  • Look for any leaks.
  • Test fan belt for deflection – it should not go more than half an inch.
  • Check fan belt for cracking or fraying.
  • Inspect radiator fins for corrosion.
  • Look at overflow tank for sludge or other types of deposits.
  • The radiator should contain a 50/50 glycol water mix.
  • Never remove the radiator cap from a recently-ran engine.
  • Do not add cold water or antifreeze mix to a hot engine.

Never attempt to check coolant in a hot engine - always wait for it to cool off.
