V8-350-CE-K 2018 coolant change every 200 hours

How do you replace the coolant (antifreeze) on the 2016 and newer Volvo penta engines that have closed cooling and the EZ drain system? The service protocol says to replace the coolant every 200 hours. Thanks.

Odd I never looked at it because I swear they put ext life 100,000 mile coolant in them.
But anyways I haven't looked but I'm sure there is drain plugs on the block. 1 on each side. That would be the easiest way to drain it. But if you have a coolant flush machine that would be the other way just like a car engine.

I'll take a look. I imagine that the drain plugs are also knock sensors. Perhaps it will be somewhat obvious which cooling lines to the heat exchanger come from the block. While I'm doing this, it would be great to tie a heater core in to use to warm the cockpit on cool days, with a valve to prevent flow, or to bypass the heater core on warm days. It could keep the life preserver storage warm for towel and clothes drying.
