Why do you want to adjust the tension on the belt? Do you have noise coming from that area?

This is for belts with auto tensioners. Let me know if it is different or if it worked out for you?

CAUTION:

Avoid placing hand in a location where pinching may occur if the holding tool accidentally comes off.
Do not loosen the auto-tensioner pulley bolt. Do not turn it counterclockwise.) If turned counterclockwise, the complete auto-tensioner must be replaced as a unit, including pulley.
Insert a rod approximately 6 mm (0.24 in) in diameter through the rear of tensioner into retaining boss to lock tensioner pulley.
Leave tensioner pulley arm locked until drive belt is installed again.
Loosen drive belt from water pump pulley and then remove it from the other pulleys.
