Q: How to service the drive belt on Toyota 4Runner?
A: The service of drive belt starts with PS pump drive belt removal along with engine under cover removal. The drive belt removal process requires adjusting the idle pulley lock nut so you can decrease tension until you can easily remove the belt. To install the new belt first apply 2.5 N.m (25 kgf.cm, 22 in.lbf) torque to the idle pulley lock nut before placing the belt. When setting drive belt tension the adjusting bolt must be utilized to achieve a new belt tension at 160 plus or minus 25 lbf and a used belt tension at 100 plus or minus 25 lbf. Following adjustment work on the idle pulley lock nut reach 39 N.m (400 kgf.cm, 29 ft.lbf) then install the PS pump drive belt before reinstalling the engine under cover.
A: The 2AZ-FE engine drive belt removal begins with removing the front right-hand wheel before proceeding with the right-side engine under cover and right-hand side front fender apron seal. The V-ribbed belt tensioner arm can be loosened through clockwise rotation using Special Service Tool: 09216-42010 coupled with a 19 mm socket wrench before removing the V-ribbed belt. Users must maintain parallel alignment of the Special Service Tool against the wrench throughout the operation while they must rotate the tensioner clockwise for at least 3 seconds at a slow pace before stopping. New torque should be minimal when the tensioner reaches full retraction.
A: The first step for drive belt removal on 2TR-FE engines requires clockwise motion on the hexagonal bolt from the V-ribbed belt tensioner followed by V belt removal.
