Daily Prestarting Checks

Check the following items BEFORE STARTING THE ENGINE for the first time each day:

• Check engine oil level on dipstick. Fill cap/dipstick may be located on left or right side, depending on application. Add as required, using seasonal viscosity grade oil. (See Diesel Engine Oil — Interim Tier 4, Final Tier 4, Stage IIIB, and Stage IV in the Fuels, Lubricants, and Coolants Section for oil specifications.)
• NOTE: Wipe all fittings, caps, and plugs before performing any maintenance to reduce the chance of system contamination.
  Check the coolant level when engine is cold. Fill radiator or surge tank with proper coolant if level is low. (See Adding Coolant in the Service As Required Section.) Check overall cooling system for leaks.
• Check radiator for leaks and trash buildup.
• NOTE: It is normal for a small amount of coolant to weep from the engine weep hole, especially as the engine cools down and parts contract. If enough coolant weeps from the engine where coolant drips from the engine, this may indicate the need to replace the coolant pump seal. Contact your engine distributor or servicing dealer for repairs.
  Check fan, alternator, and accessory drive belts for cracks, breaks or other damage.
• Loosen water drain valve on each fuel filter all the way so that the valve opens to drain water and debris as needed. Retighten valves securely. NOTE: Any water in fuel is drained into the bottom of the fuel filters. The operator is signaled by an amber indicator on the instrument panel. To service, see Draining Water From Fuel Filters in the Service As Required Section.
  
• Squeeze the automatic dust unloader valve (if equipped) on air cleaner assembly to clear away any dust buildup.
• Check air intake restriction indicator gauge and service air cleaner as required (if equipped).
• Check air intake system hoses and connections for cracks and loose clamps.
• Inspect the engine compartment. Look for fluid leaks, worn fan and accessory drive belts, loose connections, and trash buildup. Remove trash buildup and have repairs made as needed.
