accessory drive not pully
What is the torque specs on the accessory drive
how do you change seal on the accessory drive N14red top
Large drive pulley, small driven pulley = faster rotation but less torque. Small drive pulley, large driven pulley = slower rotation but more torque.
An accessory drive belt idler pulley bearing going bad.
Check the condition of the accessory drive serpentine belt, belt idler pulley and belt tensioner pulley bearings.
To remove the accessory drive belt or the serpentine belt from the motor on a 1989 Sunbird, it is necessary to loosen the belt tensioner. Look for a pulley that has a bolt in a slot. Loosen the bolt and move the tensioner so there is a gap in the belt. Then remove the belt from each pulley.
the crank sensor is located behind the main accessory drive pulley which is installed at the end of the crankshaft you have to remove the pulley and the plastic cover that covers the timing belt
Possibly the accessory belt needs tightening or replacing -or- the bearing for the drive pulley may be going bad.
REMOVAL WARNING: BECAUSE OF HIGH SPRING PRESSURE, DO NOT ATTEMPT TO DISASSEMBLE AUTOMATIC TENSIONER. UNIT IS SERVICED AS AN ASSEMBLY (EXCEPT FOR PULLEY). (1) Remove accessory drive belt. (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELTS - REMOVAL). (2) Disconnect wiring and secondary cable from ignition coil. (3) Remove ignition coil from coil mounting bracket (two bolts). Do not remove coil mounting bracket from cylinder head. (4) Remove tensioner assembly from mounting bracket (one nut) (Fig. 4) (5) Remove pulley bolt. Remove pulley from tensioner. INSTALLATION (1) Install pulley and pulley bolt to tensioner. Tighten bolt to 61 N·m (45 ft. lbs.) torque. (2) Install tensioner assembly to mounting bracket. An indexing tab is located on back of tensioner. Align this tab to slot in mounting bracket. Tighten nut to 67 N·m (50 ft. lbs.) torque. (3) Connect all wiring to ignition coil. CAUTION: To prevent damage to coil case, coil mounting bolts must be torqued. (4) Install coil to coil bracket. If nuts and bolts are used to secure coil to coil bracket, tighten to 11 N·m (100 in. lbs.) torque. If coil mounting bracket has been tapped for coil mounting bolts, tighten bolts to 5 N·m (50 in. lbs.) torque. (5) Install drive belt. (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELTS - INSTALLATION). (6) Check belt indexing marks (Fig. 4).

Remove the air intake duct, if necessary. Refer to Air Cleaner Assembly Replacement in Engine Controls - 5.7 L. Install a breaker bar with hex-head socket to the drive belt tensioner bolt. Rotate the drive belt tensioner clockwise in order to relieve tension on the accessory drive belt. Remove the accessory drive belt from the pulleys and tensioner. Slowly release tension on the drive belt tensioner. Remove the breaker bar and socket from the drive belt tensioner bolt. Clean and inspect the drive belt surfaces of all the pulleys. Route the accessory drive belt around all the pulleys except the water pump pulley and tensioner. Install a breaker bar with hex-head socket to the drive belt tensioner bolt. Rotate the drive belt tensioner clockwise in order to relieve tension on the drive belt tensioner. Install the accessory drive belt under the water pump pulley. Install the accessory drive belt onto the drive belt tensioner. Slowly release the tension. Remove the breaker bar and socket from the drive belt tensioner bolt. Install the air intake duct, if necessary. Refer to Air Cleaner Assembly Replacement in Engine Controls - 5.7 L. Inspect the accessory drive belt for correct alignment.
There is no "fan belt"; the 2.5L V-6 has two accessory drive belts, both with tensioners (loosen the large nut in the center of the tensioner pulley, and adjust the threaded adjustment rod), and the 2.0L I-4 has a single accessory drive belt with a tensioner (loosen the clamp bolt & adjust the threaded adjustment rod).
