How do you put serpentine belt on freightliner?
If the old belt is still being used,a wise thing to do is draw a picture of how it wraps around the pulley’s because it can go on many different ways but it will only fit one way. You can be there for a long time trying to figure it out. To replace it, you need a 1/2″ drive ratchet. There is a square hole in the automatic tensioner which is close to the alternator on the front.Put the ratchet in this hole and release the pressure on the tensioner. Be careful not to allow the spring pressure snap back the ratchet handle onto your knuckles!!! While either holding the ratchet or have it against something solid, just remove the belt,feed the new one on the same way and then gently release the ratchet. Make sure the belt is fully on each pulley before you start the engine.
