Monitoring the Lubricating Oil Filter

Monitoring the Lubricating Oil Filter - Ops - DD5

The engines are equipped with a single cartridge-style oil filter (3) that is part of the oil/coolant module (4). Incorporated into the housing 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.

Perform the following maintenance on the lubricating oil filter:

  1. Replace the oil filters when recommended by the appropriate maintenance table. Refer to section "GHG17 Medium Duty Preventive Maintenance Tables".
  2. Make a visual check of all lubricating oil lines for wear and/or chafing. If any indication of wear is evident, replace the oil lines and correct the cause.
  3. Check for oil leaks after starting the engine.
