Colorado 4WD L5-3.7L (2007)
Installation Procedure
Important: Use special anti-seize compound on the HO2S threads. The compound consists of graphite suspended in fluid and glass beads. The
graphite burns away, but the glass beads remain, making the sensor easier to remove. New or service sensors already have the compound
applied to the threads. If you remove an oxygen sensor and if for any reason you must reinstall the same oxygen sensor, apply the anti-seize
compound to the threads before reinstallation.
1. Coat the threads of the HO2S with the anti-seize compound P/N 5613695, or equivalent if necessary.
Notice: Refer to Component Fastener Tightening Notice.
2. Using the J 39194-B, install the HO2S into the catalytic converter.
Tighten the HO2S to 42 N.m (31 lb ft).
3. Connect the HO2S electrical connector (3) to the engine wiring harness connector (1).
4. Lower the vehicle.
