Inspection of the Lubrication System
Detroit™ Gen 5 Heavy Duty engines are equipped with a single cartridge-style oil filter that is part of the oil coolant module. Incorporated into the module is a drain back port, which allows residual oil to be returned to the oil pan when the filter is removed. This design, including the cartridge-style element, allows for a more environmentally safe oil change. The lubricating oil and filter should be replaced as recommended in the maintenance tables using the appropriate engine duty cycle, Preventive Maintenance Tables.
Checking the Lubricating Oil Level
The lubricating oil level should be inspected daily as part of the pre-start inspection, How to Check the Lubricating Oil Level. If necessary, fill the engine to the proper level with the recommended viscosity and grade of engine oil Synthetic Oils and Additives.
Checking the Lubricating System for Leaks
Check as follows:
Inspect all lubricating oil lines for wear and/or chafing.
Check for oil leaks after starting the engine.
Lubricating Oil and Oil Filter Replacement
The oil filter is an integral part of the lubrication system. Proper filter selection and maintenance are important to satisfactory engine performance and service life. Authorized Detroit™ service outlets are properly equipped for this type of service. Oil filter replacement should be used to maintain a clean system, but is not sufficient to clean a contaminated system. If the oil is contaminated by fuel or coolant, contact an authorized Detroit™ service outlet for further instructions.
