COOLANT DRAINING
2. Locate the freeze plug (Figure 7) on the engine block.
1. Locate and place a clean container below the coolant
drain port (Figure 5) to catch drained coolant. The
collected coolant will be reused later. Make sure no
foreign particulates or contaminates are present in
the drained coolant.
2. Using an open-ended wrench, remove the coolant drain
plug and drain approximately 1/2-3/4 gallons of coolant
(Figure 5) from the coolant reservoir.

2. Reconnect the negative cable (BLACK) to the negative
terminal on the battery.
3. Reinstall the coolant access panel and run the engine
for approximately 10-15 minutes to ensure engine
thermostat functionality.
NOTICE
The thermostat will open to allow complete coolant
circulation from the radiator to the engine block.
4. Turn the engine off and let cool. Check the unit for any
leaks around the water heater. If leaks are present,
repair them immediately and check the heater element
for misalignment in the freezer plug corehole.
5. Inspect the coolant level for a final time before using
the generator on a work area.
