The accessory drive belt (2) is a serpentine type belt that is driven by the crankshaft pulley (6).
The belt drives the A/C compressor, generator (3), power steering pump (1) and water pump (7). Belt tension is maintained by an automatic belt tensioner (8).

| 1 - NORMAL CRACKS ON BELT |
|---|
| 2 - NOT NORMAL CRACKS ON BELT |
When diagnosing serpentine accessory drive belts, small cracks that run across the ribbed surface of the belt from rib to rib (1), are considered normal. These are not a reason to replace the belt. However, cracks running along a rib (not across) (2) are not normal. Any belt with cracks running along a rib must be replaced. Also replace the belt if it has excessive wear, frayed cords or severe glazing.
