Installation Procedure
1. Remove the former 109-4367 or 3E-7826 Exhaust Temperature Sensor from the exhaust manifold (A). Remove the 124-0289 Clip from the valve cover (B) that holds the sensor electronics. Save the clip and hardware. Unplug the sensor connector from the main wiring harness.
Location of new components for installing the new 163-7882 or 164-2441 Exhaust Temperature Sensor Group.* 163-7872 or 165-2441 Exhaust Temperature Sensor Group (1).* 4P-7581 Straight Clip or 4P-8134 "L" Clip (2).* Previous location of 124-0289 Clip and location of new 4P-7581 Straight Clip or 4P-8134 "L" Clip (3).* HD or DT connector (4).* 124-0289 Clip (5).* Exhaust temperature sensor group electronics (6).* Exhaust Manifold (A).* Valve Cover (B).* Camshaft Cover (C).2. Using a new 0X0509 Bolt and 5M-2894 Washer, install a 4P-7581 Straight Clip or 4P-8134 Clip ("L" Clip) in the position of the 124-0289 Clip that was removed from the valve cover in Step 1. (See Item 3 in the illustration.)3. Lubricate the threads of the new 163-7882 or 164-2441 Exhaust Temperature Sensor Group (1) with 4C-5599 High Temperature Anti-Seize Compound before installation. Install the new exhaust temperature sensor in the exhaust manifold (A). Tighten the exhaust temperature sensor to a torque of 52.5 5 N m (39 5 lb ft).4. Secure the exhaust temperature sensor electronics (6) to the camshaft cover (C) using bolt, washer, and 124-0289 Clip (5) from Step 1.5. Connect the new sensor connector (4) to the main wiring harness. Secure the exhaust sensor wiring to all clips using 9X-6772 Straps. 9X-6772 Straps should also be used to secure the main wiring harness and sensor connector.
