There is a square opening on the front of the tensioner that fit a 3/8" ratchet. Place the ratchet in the opening and crank down toward the ground. You may need to slip a longer bar over the ratchet to get it down.
Put a wrench on the tensioner pulley. Turn in the direction that will introduce slack to the belt. Remove and replace. For more info visit our enthusiasts forum at www.trailvoy.com

To change the serpentine belt on a 2003 Pontiac Bonneville, loosen the tensioner pulley and remove the old belt. The tensioner pulley is the wheel in the belt system that has a bolt through the middle in a slot that can be adjusted. Put the new belt on and tighten up the pulley.
To remove the alternator from a 2003 Chevy Trailblazer, first disconnect the negative battery cable to ensure safety. Then, remove any components obstructing access to the alternator, such as the serpentine belt, which can be released by pressing the tensioner pulley. Next, detach the electrical connections from the alternator and remove the mounting bolts. Finally, carefully lift the alternator out of its bracket.
To adjust the belt tensioner on a 2003 Suzuki XL-7, first, locate the tensioner pulley. Use a socket and ratchet to turn the tensioner pulley counterclockwise to relieve tension on the belt. If the tensioner is adjustable, you may need to loosen the mounting bolts to reposition it; otherwise, check for proper tension and replace the tensioner if it’s worn out. Always refer to the vehicle’s service manual for specific procedures and torque specifications.
You don't. It employs a spring loaded automatic belt tensioner pulley located usually on the passenger side of the engine. If your serpentine belt is too loose, either the tensioner pulley has failed (possible, but unlikely) or the belt has stretched beyond the limits of the tensioner pulley and needs to be replaced (more likely).
there should be a square hole in the tensioner arm where you install a ratchet and pull the arm loose or use the bolt that holds the pulley on on the bracket above the pulley there is a square or nut type to put the ratchet on
get a new belt. loosen your belt tensioner. take off the old belt. look under your hood or on your radiator support for the diagram that shows how the belt runs from pulley to pulley. tighten the tensioner. then...good to go.
We recently replaced the serpentine belt on our 2003 Chevrolet Tracker. We were able to place a wrench (I believe it was 9/16") on the tensioner pulley and apply pressure so the pulley released tension on the belt. This however did no allow enough slack to install the new belt so we removed the idler pulley at the top center of the engine. With the idler pulley removed we were able to route the belt and with the tension released on the tensioner pulley, routed the belt under the idler pulley and reinstalled the idler pulley, then released the tensioner pulley and the belt was installed. Be sure to note the exact route of the old belt before removal so the new belt follows the same path. Hope this helps.
If you are referring to the tensioner pulley's nut size, it is usually a metric 15mm nut.
