Changing the Coolant
Hot Coolant and Steam
Can cause severe injury
or death.
During operation, some parts of the generator set can become extremely hot. To avoid
burns, allow the engine to cool sufficiently before changing the coolant. DO NOT remove the
radiator cap while the radiator is hot. Doing so could result in extremely hot coolant spraying
out. Severe burns may result.
Always stop the engine before changing the coolant. DO NOT change the coolant while the
engine is running.
Always put the generator set in OFF mode before changing the coolant. If the generator set
is in AUTO mode, the generator set may start automatically, without warning.
1. Shut down the generator set and put it in OFF mode.
2. Ensure the generator set is on a level surface and properly supported.
3. Allow the generator set to cool fully.
4. Carefully open the radiator cap, allowing any pressure to vent before removing.
5. Open the radiator drain on the bottom of the radiator and drain old coolant into an appropriate
container.
6. Drain the overflow bottle and refill.
7. Check all hoses and hose clamps. Replace if necessary.
8. Close radiator drain and refill radiator with appropriate coolant.
9. Replace the radiator cap, ensuring it is tight.
10. Clean up any spilled coolant.
11. Dispose of old coolant according to local regulations.
