Sensor, Knock: Installation: 3.2L
NOTE:
The forward sensor (1) is identified by the Powertrain Control Module (PCM) as Knock Sensor 1. The rear sensor (3) is identified by the PCM as Knock Sensor 2.
- Thoroughly clean the knock sensor mounting holes.NOTE:
Over or under tightening the sensor mounting bolts will affect knock sensor performance, possibly causing improper spark control. Always use the specified torque when installing the knock sensors. The torque specification for the knock sensor bolt is less than the typical 8 mm bolt.
NOTE:There may be a foam strip on the bolt threads. This foam is used only to retain the bolts to the sensors for manufacturing purposes. It is not used as a sealant. Do not apply any adhesive, sealant or thread locking compound to these bolts.
- Install Knock Sensor 1 (1) or Knock Sensor 2 (3) with mounting bolt (2). Tighten the mounting bolt to the proper specifications. Refer to TORQUE SPECIFICATION .
- Connect the wire harness connector (4).
- Install the oil filter housing, upper and lower intake manifolds and air cleaner housing assembly. Refer to HOUSING, OIL FILTER, INSTALLATION .
- If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level. Refer to OIL .
- Connect the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), connect the IBS connector.
- Fill the cooling system. Refer to COOLANT SYSTEM AIR EVACUATION .
- Operate the engine until it reaches normal operating temperature. Check cooling system for correct fluid level. Refer to ADDING ADDITIONAL COOLANT .
