OIL FILTER MAINTENANCE SERVICE UPDATE
AFFECTED VEHICLES
 2016MY-current Isuzu N-Series
Equipped with 5.2L (4HK1) Diesel Engines
This bulletin supersedes information bulletin SB15-J-003. This bulletin is being revised to
update Model Years. Please discard previous bulletin SB15-J-003.
INFORMATION
IMPORTANT: Be sure to confirm correct oil filter application prior to installation.
For 2016MY N-Series vehicles, a secondary oil screen was added to the oil filter
mounting adapter to keep larger debris from entering the oiling system when the oil filter
bypass valve is activated. This new secondary screen will require cleaning each time
the oil filter cartridge is replaced. Clean the screen using spray can parts cleaner.
NOTE: Refer to bulletin IB15-J-002B for important information on the new oil filter
for 2011 and newer model years.
SERVICE PROCEDURE
1. Clean the secondary oil screen using commercially-available parts cleaner (see
Figures 1 and 2).
Figure 1 – Secondary Screen
Figure 2 – Clean the Secondary Screen
2. Allow the screen to completely dry before installing the new filter.
NOTE: When removing and installing the oil filter, be sure the secondary
screen does not become separated from the filter mount. If the screen is
accidentally removed, simply press back onto the filter mount.
3. Install the new oil filter cartridge (see Figure 3).
