Issue
Symptom:
- Fuel in coolant system
- Coolant in fuel system
- Fault Code 418: Water-in-fuel indicator
- Pressurized cooling system
Root Cause:
- Shrinkage of injector sleeve seal material can create a leak path between cylinder head cooling jacket and injector bore.
- Progressive damage could be seen on the lowest injector O-ring (green), Part Number 3347937.
Verification
- Injector sleeve seal material shrinkage is only one possible cause of symptoms discussed in this document. Published troubleshooting procedures must be followed to determine root cause.
- Inspection for fuel or coolant leakage past injector sleeve seal should only be completed when other possible sources of contamination, such as fuel heaters, have been ruled out.
Verification Step:
- Injector sleeve seal leaks are to be verified in-chassis by pressurizing cooling system. See corresponding Service Manual. Reference Procedure 002-014 in Section 2.
Note : If cylinder head has already been removed, injector sleeve seal leaks can be verified by leak testing coolant passage. See corresponding Service Manual. Reference Procedure 002-004 in Section 2.
Resolution
Note : If a cylinder head with base, extended, or parts warranty coverage is found to have leaking injector sleeves, the cylinder head must be replaced. The repair option described below is not for components in warranty
- Service O-ring, Part Number 5440257, can be used to replace the lowest green injector o-ring, Part Number 3347937, as an optional repair.
- The replacement of the lowest injector o-ring must be completed on all injectors. For removal and replacement information as well as maintenance concerning injector o-rings, see corresponding Service Manual. Reference Procedure 006-026 in Section 2.
- After injectors are installed, a leak check must be performed. See corresponding Service Manual. Reference Procedure 002-014 in Section 2.
- Inspect the fuel tank and filter for contamination.
