How to remove and install the drive belt on 2003 Toyota Tundra?

The process of drive belt removal from the 5VZ-FE engine requires engine under cover removal followed by slackening the idle pulley lock nut and adjusting the bolt for drive belt tension before the final drive belt extraction. The driver must rotate the drive belt tensioner clockwise to reduce tension before removing the drive belt from a 2UZ-FE engine model. The installation of the drive belt for the 5VZ-FE engine begins with preparing the idle pulley lock nut at 2.5 N.m (25 kgf.cm, 22 in.lbf). Next, set the drive belt in place and adjust the bolt until reaching a new belt tension of 160 plus or minus 25 lbf or a used belt tension of 100 plus or minus 25 lbf. Finally, tighten the idle pulley lock nut to 39 N.m (400 kgf.cm, 29 ft.lbf) before engine under cover reinstallation. The drive belt tensioner requires counterclockwise rotation before users can install the drive belt on the 2UZ-FE engine.
