CAUTION:
The drive belt tensioner has no provision for adjustment and will be damaged if forced to travel beyond its operating range. Automatic tensioners are calibrated at the factory to provide the correct amount of tension to the belt. There is no need to check tensioners for proper tension.
NOTE:
Drive belts with automatic drive belt tensioner do not require adjustment.
NOTE:
When a drive belt is installed new or reinstalled after a service procedure, the drive belt does not fully seat into pulley grooves until engine has run for several minutes.
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 results from:
- pulley misalignment.
- excessive pulley runout.
It can be a result of a damaged pulley or an incorrectly installed pulley that was not correctly aligned.
To correct drive belt chirp:
- determine the area from where the noise comes.
- check each of the pulleys in that area with a straightedge to the crankshaft pulley.
- 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 specification:
- The A/C system is overcharged.
- The A/C condenser airflow is blocked.
