sorry but there is no belts for the transmission! if it's slipping it's most likely a clutch or band problem if it's the bands some can be adjusted from the outsid ebut should be done by a professional! if it's the clutches you have to remove and disassemble the transmission and have them replaced!
Depends on which car and which belts.
Tighten the belts
Needs to be posted in the auto section.
There is a Tensioner Pulley that you have adjust in order to tighten the belt. There is another hex bolt that can be screwed in or out depending on how you want to tighten or losen the belts. Adjust it until prefered tension is reached.
Your idler should keep the belts tight. I've had to change my tension idler on my 1997 gtp
Loosen the belts, unbolt the old alternator, bolt the new one on, tighten the belts back up.
By replacing the belt tensioner, this is a serpentine belt systems there is no adjusting the alternator bolt tighten the drive belts, if the belts are loose you must replace the belt tensioner and the belt to retain optimum performance from you Charging sytem as well as you other equipment being driven by the belt system.
Yes, the 3.0 and 4.0 both have timing chains rather than timing belts.
Check your belts for tightness or glazed edges. If the belts are loose, tighten them. If the edges are glazed, either break the glaze with a piece of scotch brite or replace the belts if they are worn.
Start by disconnecting the negative battery cable at the battery. Remove the radiator. Remove the drive belts and crankshaft pulley. Remove the Vibration Damper (Harmonic Balancer) bolt. Use a puller and remove the Vibration Damper. Reverse these instructions to reassemble. (Tighten the Vibration Damper bolt to the correct torque)
That model has several belts that have to be replaced one at a time. start on the first belt and it will have a pivot bolt and an adjustment bolt. Loosen both and you can pull the belt to have enough slack to take it off. Do the same on the rest of the belts, moving from front to rear. Place the new belts on from rear to front. Pry the accessories to tighten the belt and tighten the bolts. Repeat that several more time and that's it.
Spray the belt with belt dressing, tighten it up, or buy a new belt.
