MD2020 - coolant change and system flush

The coolant must be changed every 2. year and this year it is again time.
I use the original pre-mixed green Volvo Penta coolant used on engines from 1983-2005.
The coolant have some properties as it prevent the engine from boiling at too low temperature, prevent corrosion, preserves rubber gaskets, prevent the engine from frostbite in the winter.
You can also get the coolant as a do it your self mix but I prefer to buy it pre-mixed wich has a price around 33 USD.
The yellow Volvo VCS coolant is for the newer engines from 2006 and forward.

In this video I try to let out all the coolant the right way and also flush the system with fresh water as it must be done according to the manual
