If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley. Pry the idler back and remove the belt.If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley.

The tension on a serpentine belt is automatically set by the Idler Tension Pulley. If you find it is not correctly setting the tension, the the spring may be broken.
The zd30 has a hydraulic tensioner using an idler pulley to automatically tension the serpentine belt.
You don't. The serpentine belt tension is automatically maintained by the tensioner pulley, which is an idler pulley located on the passenger side of the system and looks like it doesn't drive anything. If the belt tension is incorrect, the tensioner pulley must be replaced. If the question meant 'how to release tension from the belt' (for removal, etc.), this is done by applying the correct size socket wrench to the tensioner pulley's center nut and rocking the pulley away from the belt.
Disconnect the battery.remove the serpentine belt.Unbolt the pulley.
There is no tension adjustment. Tension is automatically adjusted by the idler pulley.
To loosen the tension on a serpentine belt on a 2005 Grand Caravan 3.8L, turn the nut of the belt tension pulley to loosen it. Adjust the belt, then tighten the tension pulley by turning the nut in the opposite direction.
For most cars and trucks there is a diagram showing the pattern the belt should take for each pulley. This is usually located under the hood on the radiator support. The vehicles I've had experience with have an idler pulley which supplies tension on the serpentine belt. This pulley is spring loaded, by using the correct size wrench, pull up on the pulley, relieving the tension on the belt and sliding the belt off or on.
It's on the center of the idler pulley
Loosen bolt in tension pulley, then loosen tension bolt. Replace belt. Tighten tension bolt. Last, tighten bolt through pulley.
Regardless of what type of vehicle you have, it is extremely difficult to replace a serpentine belt w/o a serpentine un-tension-er tool. This is a thin, long handle with a socket on the end that sticks out at 90 degrees of the handle. The socket slips onto the bolt-head of the tension-er pulley. Once the serpentine belt is threaded around all the other pulleys you put the un-tension-er tool on the tension-er pulley bolt and pull (or push) to achieve slack in the serpentine belt and slip it on the tension-er pulley.
A ratchet isÊneeded to loosen the serpentine belt tension pulley on a 2002 Jeep Wrangler V6. It will require a 1/2 inch ratchet.
