GENERAL

A single six-ribbed belt drives all the primary engine mounted accessories and a secondary double-sided eight-ribbed belt drives the engine driven cooling fan and the supercharger.

Both the primary and secondary belts are crankshaft driven via the torsional vibration damper. An automatic tensioner, located on the LH accessory-mounting bracket, keeps the belt at the correct tension. A deflection pulley on the RH accessory-mounting bracket increases the wrap angle around the generator pulley.

The torsional vibration damper incorporates compressed rubber between its inner and outer diameters to absorb vibration and shock loads.

The automatic tensioner consists of a deflection pulley on the end of a spring loaded pivot arm. The pivot arm can be turned counter-clockwise (viewed from the front of the engine) for removal and installation of the belt.

OVERVIEW

There are two accessory drive belts on the supercharged engine and this section covers basic checks for both.

For ease of identification, the two belts are referred to as primary and secondary drive belts.

For additional information on the description and operation of the system, refer to the relevant information.

INSPECTION AND VERIFICATION

  1. Verify the customer concern.
  2. Visually inspect for obvious mechanical faults. SYMPTOM CHART Mechanical Primary drive belt condition (cracking/damage/contamination) Secondary drive belt condition (cracking/damage/contamination) Belt tension Pulley alignment Coolant pump Primary tensioner assembly Air conditioning compressor Power steering pump Crankshaft pulley Generator Dynamic response pump pulley Deflection pulley Supercharger pulley Secondary tensioner assembly Cooling fan pulley
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. CAUTION: If the engine is run without the accessory drive belts connected to eliminate driven components, diagnostic trouble codes, (DTCs) may be set which must be cleared before the vehicle is returned to the owner. The engine should not be run for more than 2-3 minutes with the belts disconnected. Failure to follow this instruction may result in damage to the vehicle.
  4. Use the approved diagnostic system or a scan tool to retrieve any DTCs before moving onto the symptom chart or DTC index. Make sure that all DTCs are cleared following rectification.

SYMPTOM CHART

SymptomPossible causeAction
NoiseBelt condition Belt tension Pulleys misaligned Driven components (including tensioners)Check the belt condition (see visual inspection). Check the tensioner function. Check the pulley alignment. Check the driven components for excessive resistance to rotation. Rectify as necessary.
Drive belt does not hold tensionBelt condition Tensioner faultCheck the belt condition (see visual inspection). Check the tensioner function. Rectify as necessary.

DTC INDEX

Note. Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system). For a full list of ECM DTCs, refer to DTC index .
