id011096801500
Drive Belt Deflection Check
1. Check the drive belt deflection when the engine is cold, or at least 30 minutes after the engine has stopped. Apply pressure 98 N {10 kgf, 22 lbf}midway between the specified pulleys.

2. If the deflection is not within the specification, adjust it. (See DRIVE BELT ADJUSTMENT [WLT-1, WLT-2].)
Drive Belt Tension Check
1. Belt tension can be checked in place of belt deflection. Check the drive belt tension when the engine is cold, or at least 30 minutes after the engine has stopped. Using the SST, check the belt tension between any two pulleys.
