Yanmar SA324 coolant replacement.

An owner-shot walkthrough of a coolant flush on a Yanmar SA324, filmed while actually doing the job past its service interval. It covers locating the tucked-away drain plug, pulling the cotter-pin metal plug, using a battery-powered transfer pump to clear the expansion tank, and refilling with the dealer-sourced YG30 red coolant. Most useful to SA324 owners tackling this maintenance for the first time.

An owner-operator documenting their own overdue maintenance, so expect candid real-world perspective with no apparent commercial angle.
