Also check for the proper belt deflection measurement. 2. Apply 100 N (22 lbs.) force to the belt back midway between the pulleys as shown in the illustration, measure the amount of deflection with a tension gauge. For 2.4L DOHC ENGINE For 2.5L V6 ENGINE The drive belt tension is adjusted automatically by auto-tensioner.
