Checking the drive belt
1. Generator; 2. Automatic drive belt tensioner; 3. Crankshaft pulley; 4. Air conditioning compressor (on models with air conditioning); Tension pulley (on models without air conditioning); 5. Water pump; 6. Drive belt; A. Range of possible operation; B. Range when installing a new drive belt; S. Pointer.
Attention:
- Perform the test with the engine off.
- Make sure the pointer (notches on a fixed part) on the automatic drive belt tensioner is within the operating range (A) in the figure.
Note:
- Check the position of the automatic tensioner indicator on a cold engine.
- When installing a new drive belt, the indicator (notches on a fixed part) must be within the range (B) in the figure.
- Perform a visual inspection of the entire belt to ensure there is no wear, damage or cracks.
