PARTS DISPOSITION

Show/hide table

Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.

Rework Procedure

Show/hide table

1. Remove middle belly guard to gain access to Powertrain Oil Cooler Tube Bolts.

2. Replace existing bolts and washers with new 8T-4184 and 8T-4194 Bolts and new 164-6819 Washers. Tighten the bolts to a torque of 100 +/-20 Nm (73 +/-15 lbs ft.)

(See Image 1.1.1 and Image 1.1.2)

-Thicker washers prevent bolt heads from interfering with tube elbow. Which in turn, creates more surface area for torqueing.
