Lubrication System
Lubrication System - Gen 5 DD15 - Ops - #7628
The lubrication system of a Detroit™ Gen 5
Heavy Duty engine consists of an oil coolant module, oil filter, oil
cooler, oil pan, oil pump, oil suction manifold, oil pressure regulator
valve, oil thermostat, and oil pressure sensor. Clean, pressurized
oil is fed to all components via passages in the engine block and
cylinder head.
Always use lubricating oils and oil filters that
meet Detroit™ specifications. The use of lubricating oils and/or
oil filters that do not meet Detroit™ specifications may result
in premature wear or engine failure. Consult with an authorized Detroit™
service outlet to obtain the proper engine oil filter.
For additional information on selecting lubricating oil, see Synthetic Oils and Additives. For a listing of required
lubrication system service intervals, see Preventive Maintenance Tables.
