Check the multi-ribbed belt for signs of wear like these - if the belt looks worn, renew it

1 The alternator, power steering pump, coolant pump (VVT-i engines) and air conditioning compressor drivebelt(s), also referred to as simply 'fan' belts, are located at the right end of the engine. The good condition and proper adjustment of the belts is critical to the operation of the engine. Because of their composition and the high stresses to which they are subjected, drivebelts stretch and deteriorate as they get older. They must therefore be periodically inspected.

2 The number of belts used on a particular vehicle depends on the engine type and accessories installed. On Non-VVT-i engines, one belt transmits power from the crankshaft

to the coolant pump and alternator. If the vehicle is equipped with power steering and/ or air conditioning, a separate belt (or two separate belts) drive these components. On

VVT-i engines one belt is used to drive all the pulleys.

3 With the engine stopped, open the bonnet and locate the drivebelt(s). With a torch, check each belt for separation of the adhesive rubber on both sides of the core, core separation from the belt side, a severed core, separation of the ribs from the adhesive rubber, cracking or separation of the ribs, and torn or worn ribs or cracks in the inner ridges of the ribs

(see illustration). Also check for frayingand glazing, which gives the belt a shiny appearance. Both sides of the belt should be inspected, which means you will have to twist the belt to check the underside. Use your fingers to feel the belt where you can't see it. If any of the above conditions are evident, renew the belt.

4 On non-VVT-i engines only, to check the tension of each belt, the following rule of thumb method is recommended: Push firmly on the belt with your thumb at a distancehalfway between the pulleys and note how far the belt can be pushed (deflected). Measure this deflection with a ruler (see illustration).

The belt should deflect approximately 6.0 mm if the distance from pulley centre to pulley centre is between 200 to 300 mm; the belt should deflect approximately 12 mm if the distance from pulley centre to pulley centre is between 300 and 400 mm. Note: On VVT-i engines, the tension of the belt is maintained by an automatic tensioner mechanism.
