Installation Procedure
WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, 2010 Chevrolet Silverado, and 2010 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
- If reinstalling the old temperature sensor or differential pressor sensor line fittings, coat the threads with anti-seize compound GM P/N 12377953, or equivalent.
- Position and install the exhaust differential pressure sensor pipe assembly to the vehicle.
- Tighten the exhaust differential pressure sensor pipe assembly fittings (1).
Tighten: Tighten the fittings to 45 N.m (33 lb ft).
- Position the exhaust differential pressure sensor pipe bracket to the exhaust hanger and install the bolt and nut.
Tighten: Tighten the bracket bolt/nut to 9 N.m (80 lb in).
- Install the exhaust differential pressure sensor pipe assembly hoses to the sensor.
- Position the exhaust differential pressure sensor pipe assembly hose clamps (3).
- Lower the vehicle.
NOTE:
A special anti-seize compound is used in the sensor or line fittings threads. The compound consists of liquid graphite and glass beads. The graphite tends to burn away, but the glass beads remain, making the sensor or line fitting easier to remove. New, or service replacement sensors or line fittings already have the compound applied to the threads. If the sensor or line fittings are removed from an exhaust component and if for any reason the sensor or line fitting are reinstalled, the threads must have anti-seize compound applied before reinstallation.
NOTE:
Ensure to route the pipe assembly over the frame crossmember.
CAUTION:
Refer to Fastener Caution
