Is My Yanmar Tractor Cooling System Leaking?

We want to help you test your Yanmar tractor’s cooling system for leaks.





If you do not feel that you understand these steps, or can perform them safely, consult your tractor dealer or local mechanic.


Time to get started.





Testing the Cooling System


To check your tractor engine coolant system for leakage:


1. With the radiator properly filled, install a cooling system tester (Figure 8-3, (1)).


2. Apply 10.8 - 14.8 psi (75 - 105 kPa; 0.75 - 1.05kgf/ cm2) to the cooling system. If the pressure reading drops, the engine coolant system is leaking.


3. Identify the source of the leak and repair.




If you need any further help or have any questions about cooling systems, tractors, or anything else, please contact your dealer, local mechanic, or call us at 602-734-9944. Please ask about our current new and used tractor supply.
