INSTALLATION - SRT

  1. Position the ignition coil (3) on the cylinder head cover.
  2. Install the ignition coil retaining bolt (2). Tighten the bolt to 8 N.m (71 in. lbs.).
  3. Connect the ignition coil wire harness connector (1) to the coil pack. NOTE: When installing the spark plug cables, route the cables correctly. Failure to route the cables properly can cause improper spark plug phase-shift.
  4. Install the spark plug cables to the appropriate coil tower (A & B) (coil side).
  5. Install the spark plug cables to the appropriate spark plug location (G & K) (plug side). NOTE: Refer to the reference pad cast into the cylinder head cover to identify proper spark plug/spark plug cable orientation. NOTE: When installing spark plug cables, insure a positive connection is made. A snap should be felt when a good connection is made between the spark plug cable and the spark plug.
  6. Insure a firm connection is made from the spark plug cables (3) to the spark plugs.
  7. Install the upper air cleaner housing. «(Refer to ENGINE/AIR INTAKE SYSTEM/AIR CLEANER HOUSING - INSTALLATION)»(ref-250616-S27034750232007031500000) .
  8. Install the engine cover (1). Align the engine cover retaining clips to the rubber mounts, and push down firmly to connect engine cover to rubber mounts. NOTE: To ease the installation of the engine cover, apply a small amount of lubricant to the engine cover rubber mounts.
  9. Connect the negative battery cable.

The 3.2L engine is equipped with two knock sensors. The knock sensors bolt onto the cylinder block below the intake manifold in the engine valley. They are designed to detect engine vibration that is caused by detonation.

INSTALLATION

Note. The knock sensor bolt torque is higher than other sensors. If the proper torque is not applied to the knock sensor, driveability can be affected.

  1. Position the knock sensors (1) on the engine block.
  2. Install the knock sensor retaining bolts. Tighten the bolts to 20 N.m (15 ft. lbs.).
  3. Connect the wire harness connectors.
  4. Install the intake manifold. «(Refer to ENGINE/MANIFOLDS/INTAKE MANIFOLD - INSTALLATION)»(ref-250615-S06489389382007031500000) for 3.2L - Service Information or «(Refer to ENGINE/MANIFOLDS/INTAKE MANIFOLD - INSTALLATION)»(ref-250616-S22344483332007031500000) 3.2L SRT - Service Information .

The engine uses platinum tip resistor spark plugs. Platinum-tip spark plugs allow 100,000-mile (161,000-km) replacement intervals in normal service. They have resistance values of 6,000 to 20,000 ohms when checked with at least a 1000 volt tester. For spark plug identification and specifications, (Refer to ELECTRICAL/IGNITION CONTROL - SPECIFICATIONS) .

Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate reading.

Spark plugs using either a single or double platinum tips have a recommended service life of 100,000 miles for normal driving conditions per schedule A in this information. The spark plugs have a recommended service life of 75,000 miles for severe driving conditions. A thin platinum pad is welded to both or just the center electrode (2) end(s). Extreme care must be used to prevent spark plug cross threading, incorrect gapping, and ceramic insulator damage during plug removal and installation.

CAUTIONCleaning of the platinum plug may damage the platinum tip.

REMOVAL

CAUTIONWhen disconnecting a high tension cable from a spark plug or from the ignition coil, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force.
  1. Remove the spark plug cable boot from the ignition coil (1).
  2. Turn and pull the spark plug cable metal clad boot (2) from the spark plug.

Note. When installing the spark plug cables, route the cables correctly. Failure to route the cables properly can cause improper spark plug phase-shift.

  1. Install the spark plug cables to the appropriate coil tower (A & B) (coil side).
  2. Install the spark plug cables to the appropriate spark plug location (G & K) (plug side). NOTE: Refer to the reference pad cast into the cylinder head cover to identify proper spark plug/spark plug cable orientation. NOTE: When installing spark plug cables, insure a positive connection is made. A snap should be felt when a good connection is made between the spark plug cable and the spark plug.
  3. Insure a firm connection is made from the spark plug cables (2) to the spark plugs.
