Need to drain , flush and refill coolant in our power tech generator , I can see it's a sealed system and unsure how to proceed, any advice or thoughts would be greatly appreciated . Thanks
Jimmy, I too would like to learn about this.
I'm thinking about changing my coolant. It will be awhile tip I actually get to it but was doing some checking. On mine, there appears to be a drain on the bottom side of the radiator. It is front right as you look into the compartment below driver's window.
Hope this helps,
Rich
