Maintenance of the cooling system
When the engine is operating, there must be enough antifreeze and distilled water in the radiator
system to insure proper engine cooling. It is suggested to check it regularly before use, if there is
not enough antifreeze or distilled water add as needed. Do not use mineral, hard water or poor-
quality antifreeze. We suggest Prestone, Shell, Texaco or similar brand.
1. Replace antifreeze and distilled water as outlined in the service guide or if discolored to a brown
watery mix. Combine antifreeze and distilled water only to manufactures suggested guidelines.
Do not replace cooling liquid when the engine is hot.
After prolonged use or time, the coolant can go bad and discolor. Follow the recommended steps
as outlined below.
• Place pan under pre-plumed coolant or water line pipe. See photo above.
• Open coolant or water line pipe valve and allow it to drain completely.
• Remove or wipe any old excess water.
• Close coolant or water drainpipe line valve.
• Refill radiator cooling system and reservoir until full.
• Start the generator without load for a few minutes. Allow for air pockets in the system to settle.
Shut down generator and add additional coolant as needed until the level remains steady.
• Shut down generator again and add coolant to the "FULL" level mark
• Make sure the expansion tank is filled halfway between low and full mark.
• Install radiator cap and expansion tank cover. Inspect system carefully to make sure there are no leaks.
Hard water, mineral water and saline water is harmful to the engine and cooling
