It covers removing the bonnet, draining via the lower radiator hose instead of the hard-to-reach drain plug, flushing repeatedly with fresh water until clear (five passes shown), refilling with 50/50 antifreeze, bleeding air, and checking for leaks at operating temperature. Best for owners ready to do this exact job themselves.

Remove the lower radiator hose instead of the hard-to-reach drain plug. Also remove the radiator cap and disconnect the overflow tank hose so everything drains completely.
The video shows flushing with fresh water five times, running the engine three to five minutes each time, until the drained water comes out clear.
Use Kubota's 50/50 pre-diluted antifreeze coolant, which is green conventional coolant. Never mix it with long life orange or red coolant since that creates sludge.
Fill slowly to avoid trapping air, then run the engine with the radiator cap off for three to five minutes at low idle before replacing the cap.
