Failure to route the cables properly could cause the radio to reproduce ignition noise, cross ignition of the spark plugs or short circuit the cables to ground.

NOTE: REMOVE cables from coil first before removing spark plug insulator.

Special care should be used when installing spark plugs in the 2.4L cylinder head spark plug wells. Be sure the plugs do not drop into the wells, damage to the electrodes can occur.

Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap. Overtightening can also damage the cylinder head.

  1. To avoid cross threading, start the spark plug into the cylinder head by hand.
    WARNING: The tapered seat plugs for this application are torque-critical! It is imperative that 17.6 N.m +/- 2 (13 +/- 2 ft. lbs.) is NOT exceeded!
  2. Tighten spark plugs to 17.6 +/- 2 N.m (13 +/- 2 ft. lbs.) torque.
  3. Install spark plug insulators over spark plugs. Ensure the top of the spark plug insulator covers the upper end of the spark plug tube.
  4. Install spark plug cable to coil.
  5. Install the upper intake manifold, refer to 1.6L SOHC or 2.4L DOHC for more information
  6. Connect the negative battery cable.
  7. Install the air cleaner lid and connect the inlet air temperature sensor and makeup hose.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
