COOLING SYSTEM MAINTENANCE
When the engine is in operation, there must be enough coolant in the radiator system to allow for proper circu-
lation. It is important to check this level regularly! Only use clean distilled water and high quality antifreeze.
See Owner’s Manual for more info and approved coolants.
Do not replace cooling liquid when the engine is hot!!!!!!
Check coolant effectiveness by using coolant tester during annual inspection of system. If needed, change
coolant.
CHANGING COOLANT
• Remove front cover panel.
• Locate pre-plumed coolant line with drain plug. Open drain plug with included 10mm Alan wrench and allow
coolant to drain.
• Close drain plug securely.
• Rell with approved coolant and distilled water.
• Start genset without load for 1 minute. Allow air pockets to dissipate. Stop generator.
• Add cooling liquid to the radiator full level.
• Fill the expansion tank with coolant to the “FULL” level.
• Install the radiator cap and expansion tank cover. Inspect thoroughly for leaks!
Hard water, saline water or mineral water is harmful to the engine.
Only use distilled water.
If not available, boil water and allow cooling before adding to radiator.
