Overview
This is a raw, hard-to-follow field diagnosis of a suspected head gasket leak on a Yanmar YM1610, with the owner testing a cooling-system additive/flush before deciding whether to pull the head. It's not a teardown video, just the troubleshooting step: adding a flush product, running the engine, and planning a follow-up. Useful mainly for owners chasing a similar cooling/head gasket issue rather than buyers researching the tractor generally.
