Checking Drive Belts: Notes

WARNING: This page is about a different car, the 2004 Nissan Murano and 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Be sure to perform when the engine is stopped.

Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
Inspect drive belt deflection or tension at a point on belt midway between pulleys.
- Inspection should be done only when engine is cold, or over 30 minutes after engine is stopped.
- Measure belt tension with tension gauge (BT3373-F or equivalent) at points marked shown in the figure.
- When measuring deflection, apply 98 N (10 kg, 22 lb) at the marked point.
- Adjust if belt deflection exceeds the limit or if belt tension is not within specifications.

CAUTION:

When checking belt deflection or tension immediately after installation, first adjust it to the specified value. Then, after turning the crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection between pulleys.
Tighten idler pulley lock nut by hand and measure deflection or tension without looseness.
