t  Hose clamp -T20167-, see equivalent → Anchor

t  Spanner -T20126-, see equivalent → Anchor   Note t  Before removing, mark the direction of rotation of the Poly-V belt and remember for assembly. If fitted against the direction of rotation the belt will deteriorate. t  If any faults are observed, the Poly-V belt should be immediately replaced to avoid malfunction. t  There is no need to readjust the tension of the Poly-V belt, since a spring-driven tension device always guarantees optimum belt tension. Removing

–  Detach the outer -1- and inner -2- engine covers, by pulling them evenly upwards. –  Mark running direction of poly V-belt. Vehicles without air conditioning

–  Push the tensioning element in the direction of the -arrow- to release the Poly-V ribbed belt.

–  Lock tensioner with retention tool -T20167-. –  Remove the ribbed belt. Vehicles with air conditioning

–  Rotate the tensioning element with the spanner -T20126- and lock it with the retention tool -T20167-. –  Remove the ribbed belt. Fitting Install in the reverse order from removal, remembering the following:   Note t  Ensure, before installing Poly-V belt, that all ancillaries (alternator, air conditioning compressor) are secured tightly. t  When fitting the Poly-V belt check belt rotation direction and that the belt is seated correctly in the belt pulleys. t  For those vehicles not fitted with air conditioning, fit the Poly-V belt lastly on the alternator. t  For vehicles with air conditioning, put Poly-V belt over air conditioning compressor last. –  Start engine and check that belt runs properly.
