SERVICE INFORMATION
If a 1993-98 Altima exhibits excessive timing chain noise, the cause may be a broken tension-side timing chain guide on the lower timing chain. A new,
metal-backed tension-side timing chain guide is available to resolve this incident.
For any reason whenever this guide is replaced, use the new countermeasure parts listed in Parts Information. The new guide along with the two bolts
that secure it must be installed as a set (see Figure 1).
SERVICE PROCEDURE
Diagnosis
1.
To isolate the noise, use a stethoscope or similar tool and listen at the front cover area.
