Drive Belt: Testing and Inspection

Checking drive belt

4. Undo the Y intake fittings on the left and right on the hot film mass air flow sensor. To do this, pull the locking clips vertically upwards.
5. Disconnect the hot film mass air flow sensor and remove the Y pipe from the vehicle.





6. Using chalk, mark the drive belt in the area around the tensioning roller.
7. Turn engine at the vibration damper in the direction of operation using a socket wrench (a/f 19) until the chalk mark is at the same place again. While turning at the crankshaft, check the belt at the deflection rollers for signs of damage.
