Version 2

 

Safety Recall: 3.5L V6 Timing Belt

Supersedes 19-045, dated April 12, 2019, to revise the information highlighted in yellow

 

AFFECTED VEHICLES

 

 

REVISION SUMMARY

• Under REQUIRED MATERIALS, the Honda Genuine Motor Oil part number was updated.
• Under INSPECTION, Step 5 was changed.

 

BACKGROUND

During production, a supplier produced some timing belts that do not meet specification. These timing belts may shred or slip, causing the cam shafts to fall out of timing. Camshafts that are out of timing will set DTC P0341: CMP Sensor and CKP Sensor Incorrect Phase Detected and/or DTC P0369: CMP Sensor Circuit Intermittent Interruption and the engine will run rough. Additionally, shredded timing belts may cause the vehicle to stall and not be able to restart, which increases the risk of a crash.

 

CUSTOMER NOTIFICATION

Owners of affected vehicles will be sent a notification of this campaign.

Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Some vehicles affected by this campaign may be in your new or used vehicle inventory.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it.

 

CORRECTIVE ACTION

Inspect the timing belt and, if necessary, replace the timing belt. If the lot codes are not visible or the timing belt is damaged, a cylinder leak down test may be required and, based on those results, further repairs may be required.

NOTE

Only a small percentage of vehicles are expected to have timing belts that are out of specification. Only order replacement parts after you have identified an out-of-spec timing belt.

 

PARTS INFORMATION

NOTES

• Parts are applicable to all models unless otherwise noted.
• Only a small percentage of vehicles are expected to have timing belts that are out of specification. Only order replacement parts after you have identified an out-of-spec timing belt.
• Order the engine block and the applicable cylinder head(s) after a damaged engine is identified by completing a cylinder leak-down test.

3.1 Remove the 5 bolts.

3.2 Remove the rear upper timing belt cover.

4. Mark the side of the timing belt as shown with a grease pen or marker.

5. Rotate the engine clockwise until you see the timing belt manufacturing information (lot code) or until the mark you made on the timing belt is visible again.

NOTES

You may need to rotate the engine several times before either the lot code or the mark you made is visible.

• If the lot code is visible, go to step 6.
• If the lot code is not visible, go to TIMING BELT REPLACEMENT.

6. Check the Lot Code.

• • If the Lot Code is listed in the table, go to step 7.
  • If the Lot Code is not listed in the table, the timing belt is okay, and the inspection is complete. Reassemble the vehicle in the reverse order of removal.

 

7. Check the belt position code.

• • If all of the belt position values are less than 170, the timing belt is okay. Reassemble the vehicle in the reverse order of removal.
  • If any of the belt position values are 170 or more, go to TIMING BELT REPLACEMENT.

 

TIMING BELT REPLACEMENT

1. Turn the crankshaft so its white mark on the crankshaft pulley lines up with the pointer.

NOTE

The other pointer is not used.

2. Install the upper timing belt cover, and check that the No. 1 piston top dead center (TDC) mark on the front camshaft pulley and the pointer on the front upper covers are aligned.

NOTES

• If the marks are not aligned, rotate the crankshaft 360 degrees, and recheck the camshaft pulley mark.
• If the marks still do not align, remove the original timing belt, install the new timing belt, then check the alignment again.
