System Notes — COOLING SYSTEM
The cooling system covers the radiator, water pump, thermostat, fan and fan drive, coolant hoses, clamps, the surge tank and the belts that drive it. It holds engine temperature inside the range where clearances and oil film stay correct. Failures are usually slow and then sudden: a hose softens and balloons before it bursts, a water pump seal starts weeping from the weep hole, a thermostat sticks partly open so the engine runs cold and burns more fuel. On construction sites the radiator also packs with dust and debris, which raises pressure across the core and finds the weakest hose or clamp first.
System Notes — SERVICE EQUIPMENT AND SUPPLIES
This group covers the equipment and consumables used to service the machine rather than to run it: filter wrenches and service tools, drain and fill hardware, grease fittings and couplers, sight gauges, sampling valves, and the small hardware that makes routine maintenance possible without improvising. Items here are replaced when they no longer seal, no longer hold a setting, or when a stripped fitting turns a ten-minute service job into a two-hour one. Keeping the correct part number on hand matters more than the unit price, because a missing grease coupler usually means a missed lube point.
