The lubrication system is a full-flow filtration, pressure feed type. The balance shaft module (BSM) is mounted below the ladder frame and chain driven by the crankshaft. The BSM consists of a non-serviceable pump, oil pressure relief valve, and a non-serviceable balance assembly.
Scheme 185
Note. Not all blocks have the bolt on timing chain oil squirter. Engine blocks either have a bolt-on oil squirter or a 1.0 mm hole (1) drilled into the oil gallery passage. Engine blocks with the 1.0 mm hole no longer use an oil squirter even though the threaded mounting hole may still be present.
Note. The oil cooler can not be cleaned out. In the event that the engine requires rebuilding or replacement, the oil cooler should be replaced.

Scheme 192
Note. The engine must be HOT when checking oil level.
The best time to check engine oil level is after the engine is at operating temperature. Allow the engine to be shut off for at least 5 minutes before checking oil level.
Scheme 193
Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level reading. Remove dipstick (1), and observe oil level. Add oil only when the level is at or below the SAFE mark. If the oil level is in the safe (2) range, do not add oil.
| CAUTION | Do not operate engine if the oil level is above the MAX mark on the dipstick. Excessive oil volume can cause oil aeration which can lead to engine failure due to loss of oil pressure or increase in oil temperature. |
| CAUTION | Excessive use of brake parts cleaner to clean threads in block could cause #5 main bearing failure. |
Note. Rear plug shown in illustration, other plugs are similar.
- Use Mopar® Brake Parts Cleaner (or equivalent) sparingly to clean the block.
- Install the plug (2) flush with the block boss face (1). The plug (2) is correctly installed when it is flush or protruding no more than 1 mm from the block boss face (1).
Scheme 194
