Release the tension with tension pulley. Follow belt pattern printed on a sticker under the hood
The tension pulley is centerline with the engine and at the very top of the belt routing.
Will be the only pulley that is spring loaded and not connected to an engine component
tension pulley is an automatic tensioner that keeps the serpentine belt at the proper tension it is a single pulley that is smooth (no grooves) usually turning clockwise with constant pressure loosens pulley for belt removal use caution pulley is spring loaded
Yes, it is used to adjust the tension on the A/C compressor. Looking into the engine compartment from the passenger side it is to the left of the alternator. To adjust tension you need to loosen the bolt which holds the pulley and then adjust the bolt which is directly above the pulley. Once you have proper tension tighten the pulley bolt.
No I don't think so.
The zd30 has a hydraulic tensioner using an idler pulley to automatically tension the serpentine belt.
When looking at the engine from the front, the tension pulley is the only wheel on the drive belt that has the belt on the inside of it. All of the other pulleys have the belt going around the top of the pulley. The tension pulley has a bolt that can be loosened and then tightened to remove the drive belt.
Look on the passenger front side of the engine, you will see pulley attached to a short arm with a square hole. That is the tensioner and tensioner pulley
It could be the bearing in your tension pulley.
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
