Yanmar YM 155d Should Run A Lot Cooler Now That It's Not So Restricted.

This is a rambling personal-project update, not a focused tutorial: the owner replaces a restrictive coolant hose and fittings on his YM155D, removing a stepped-down original setup he believes was choking coolant flow, while also rewiring the tractor's electrical system (fuse block, temp gauge, lights, clutch switch) and clearing out old burnt wiring. Good for owners curious about this specific cooling fix and a messy rewire, not a clean how-to.

An owner-operator casually documenting his own DIY repair work on his tractor, with informal narration rather than polished instruction.
