Taurus V6-3.0L DOHC VIN S (2000)
Drive Belt: Description and Operation
This vehicle is equipped with:
-
a V-ribbed serpentine accessory drive belt.
-
automatic drive belt tensioners.
New drive belts should be of the same type as originally installed.
Drive belt chirp is a regularly occurring chirping noise that occurs due to:
-
pulley misalignment.
-
excessive pulley runout.
It can be a result of a damaged pulley or an incorrectly replaced pulley that was not correctly aligned.
To correct drive belt chirp:
-
determine the area where the noise comes from.
-
check each of the pulleys in that area with a straightedge to the crankshaft pulley for front accessory drive.
-
look for the accessory pulley to be out of position in the fore/aft direction or at an angle to the straightedge.
Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain conditions such as:
-
engine start-up.
-
rapid engine acceleration.
-
A/C clutch engagement.
Drive belt squeal can occur under the following conditions:
-
The A/C discharge pressure goes above specifications:
+
The A/C system is overcharged.
+
The A/C condenser airflow is blocked.
