What this video covers
An intermittent coolant leak on a Universal M25-XPB diesel engine, present for a month and requiring occasional coolant top-offs, is traced using a magnifying mirror and a flashlight.0:24 Inspection reveals a rusted, loose hose clamp on the hose running to the oil cooler.0:50 Replacing the clamp alone fails to seal the leak; closer inspection shows the hose end has rotted through.0:58 A replacement piece — 11-inch, 1¼-inch diameter wire-reinforced flexible hose — is sourced from a Napa auto parts store for $14.44.1:15 The new hose seats correctly and stops the leak.1:34 A separate unrelated issue surfaces during the repair: a wire that burned in half, origin unknown, is noted but left for a later fix.1:56 The repair confirms that a rusted clamp on a diesel raw-water or coolant circuit is worth inspecting beyond the clamp itself, since the underlying hose may have deteriorated at the fitting end.
