Before starting, fill engine with oil and coolant meeting specifications. (See DIESEL ENGINE BREAK-IN OIL and DIESEL ENGINE COOLANT SPECIFICATIONS in Fuels, Lubricants, and Coolant section.)

  • Observe engine coolant temperature and engine oil pressure. Temperatures and pressures will vary between engines and with changing operating conditions, temperatures, and loads.
  • Refer to oil pressure and coolant temperature specifications in GENERAL OEM ENGINE SPECIFICATIONS in Specifications section.
  • If coolant temperature rises above maximum coolant temperature (see GENERAL OEM ENGINE SPECIFICATIONS), reduce load on engine. Unless temperature drops quickly, stop engine and determine cause before resuming operation.
  • Operate the engine under a lighter load and at slower than normal speed for first 15 minutes after start-up. DO NOT run engine at slow idle.
  • Stop engine immediately if there are any signs of part failure. Symptoms that may be early signs of engine problems are:
    • Sudden drop in oil pressure
    • Abnormal coolant temperatures
    • Unusual noise or vibration
    • Sudden loss of power
    • Excessive black exhaust
    • Excessive fuel consumption
    • Excessive oil consumption
    • Fluid leaks
