Engine Operating Guidelines
RG,RG34710,5552 –19–20MAY96–1/1
Normal Engine Operation
Observe engine coolant temperature and engine oil
pressure. Temperatures and pressures will vary
between engines and with changing operating
conditions, temperatures, and loads.
Normal engine coolant operating temperature range is
82°—94°C (180°—202°F). If coolant temperature rises
above 112°C (234°F), 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.
IMPORTANT: Should the engine die while
operating under load, immediately
remove load and restart the engine.
Overheating of the turbocharger
parts may occur when oil flow is
stopped.
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
