Condition

Some customers may comment on a water leak between the first tonneau or cargo cover and the midgate.

Cause

The striker for the front tonneau or cargo cover may need to be moved forward to improve the cover seal compression to the midgate.

Correction

1. Inspect the water drain troughs or gutters (1) to ensure they have not become dislodged and to ensure they are not plugged with debris.

Adjust and clean the drains if necessary.

2. Water test to determine where the leak is taking place. Note that water in the drain troughs or gutters on either side of the bed is normal, and

is part of the water management system.

3. Mark the tonneau or cargo cover seal in the suspected leak area.

4. Remove the tonneau or cargo covers.

5. With emphasis on the suspected leak area, inspect the seals to ensure they are in good condition. Ensure that the seals are not deformed,

damaged, twisted or out of position in such a manner that would allow a leak to occur.

6. Inspect the seal clearance and compression in the vicinity where the leak point is suspected using the following procedure:

1. Cut a piece of transparent sheet to approximately 50 mm X 275 mm (2 in X 6 in) or use paper currency in good condition.

- Transparent sheet measures approximately 0.10 mm (0.004 in) thick.

- Paper currency measures approximately 0.07 mm (0.003 in) thick.

2. Position the transparent sheet or paper currency (1) so that 1/2 will extend above the tonneau or cargo cover front seal.

3. While holding the sheet or currency at the suspected leak area, install the front cover securely. Secure the LH side latch first, then the RH

latch.

4. Grasp the sheet or currency and attempt to move side to side within the cover seal to midgate joint. Observe the amount of resistance.

5. At the area of least resistance, likely the leak point, attempt to lift and remove the sheet or currency from the cover seal to midgate joint.

Observe the amount of resistance. Removal of the sheet or currency should be met with a moderate amount of resistance.

6. If the sheet or currency can be removed with little resistance, then the cover seal to midgate joint requires adjustment. Increase

compression on the cover seal to the midgate by adjusting the striker on the affected side with the following steps:

1. Mark the position of the striker.

2. Loosen the two striker retaining bolts.

3. Slide the striker forward slightly and retighten the bolts.

4. Re-inspect the cover seal to midgate joint for proper clearance and compression.

5. Repeat the adjustment and inspection process until the correct seal clearance and compression is achieved.

7. The remaining strikers on the same side of the vehicle may need to be repositioned to maintain proper cover to cover seal clearance and

compression.

8. Once the strikers are readjusted, install the tonneau or cargo covers. To ensure proper location, install each cover in order, securing the LH

side latch first, then the RH latch.

9. Verify that the cover to cover seal interfaces are correct by sighting each joint from cross vehicle position to ensure that the interfaces are

parallel and uniform. Refer to the image above.

10. If the covers are not properly aligned, remove the covers and adjust the striker positions opposite the repair side to align the seal interfaces.

Once the adjustment is complete, reinstall the covers in order, securing the LH side latch first, then the RH latch.

11. Thoroughly test the entire tonneau or cargo cover sealing system, including the side opposite the repair, for water leaks to ensure a complete

repair. Repeat the adjustment process if water leaks are still observed.
