6. Remove the exhaust differential pressure sensor pipe assembly.
Installation Procedure
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.
1. 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.
2. Position and install the exhaust differential pressure sensor pipe assembly.
3. Loosely install the exhaust differential pressure sensor bracket bolts (1).
Caution: Refer to Fastener Caution (See: Service Precautions/Vehicle Damage Warnings/Fastener Caution).
