The drive belt is Serpentine so all you have to do is grab a 14mm socket and turn counter clockwise. This will force the pulley down enabling you to remove the belt.
It's usually on the inside of the hood when you open it, just look up.
Around 90,000 to be safe but I've seen them changed at 100,000 miles
set the harmonic balancer pully to zero there are 2 notches on the cam shaft pullies that should align with a mark on the mounts
Remove fan clutch with fan impeller. Remove A/C compressor drive belt. Remove cap from tensioning roller. Relieve tension on drive belt. Remove drive belt. Reverse procedure for installation.
It's best to do because you have to have the front and top of the engine apart so might as well do it while it's apart.
remove clutch cover. remove old belt. install new belt.
Have this done by a professional. It requires a torque wrench and knowledge of the necessary tightness to safety secure a new seat belt. This is not something you want to DIY.
no just take it off a few pulleys to give u slack when removing the water pump
Set the parking brake and disconnect the spark plug wire. Remove the cutting deck and the battery. Loosen the pulley and remove the upper belt. Remove the belt guide and the belt keeper. Loosen the bolt on the crankshaft pulley. Remove the lower drive belt.
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.
Yes you can remove it and still drive the truck......
It's a pain, I just changed the one on my '94, remove the positive battery cable, remove the belly pan, remove the serpentine belt, remove two bolts that hold the alternator, disconnect the wiring connector and the hot wire nut, remove some of the hose and tubing clamps so you can drop the alternator down through the bottom and reverse the procedure to install. It's a pain, and I know I did some cursing so take your time.
