ALTERNATOR DRIVE BELT NOISE
APPLIED VEHICLE:
2000-05 Sentra (B15) with QG18DE Engine
APPLIED DATE:
Vehicles built before July 9, 2005
IF YOU CONFIRM:
An applied vehicle has a chirp or squealing noise coming from the drive belt area as described below:
^
A chirp noise occurs at start-up in the morning especially in cold or damp conditions.
^
A squealing noise occurs at idle and low engine speeds. As the engine speed increases, the squealing noise goes away.
ACTION:
^
Replace the alternator drive belt with the one listed in the Parts Information section of this bulletin.
^
Refer to the Service Procedure for the specific drive belt adjustment tension (for "New Belt") and tightening torques.
IMPORTANT DRIVE BELT TENSION INFORMATION:
After you install the new drive belt:
^
First, adjust it to the specified tension (for "New Belt").
^
Second, turn the crankshaft two or more turns to set the drive belt into the pulley grooves.
^
Then, re-adjust to the specified tension (for "New Belt").
^
It is critical to use a belt tension gauge when adjusting the belt tension. Belt tension that is out of specification can result in the eventual degradation
of the drive belt material causing future noise complaints.
^
The Kent-Moore part number for the belt tension gauge is BT-3373-F.
