Generator Coolant shutoff valves
Attached is a picture of my driver's side generator compartment. It has the coolant overflow bottle, the coolant reservoir, the blower/radiator and the windshield washer fluid bottle. If you look in the upper right corner, you can see two coolant shutoff valves with yellow handles. They connect to the coolant reservoir. Should these be open or closed and why?
It appears that the similar lines on the engine don't have any valves and are therefore open.
Thanks,
Rich
