Refitting
4 Commence refitting by positioning the tensioner on the cylinder block, ensuring that the lug on the rear of the tensioner bracket engages with the corresponding hole in the cylinder block. Tighten the securing bolt.

5 Swing the alternator into position, to align the upper mounting bolt hole with the corresponding hole in the drivebelt tensioner assembly. Refit the upper mounting bolt, and tighten the upper bolt and lower through-bolt.

6 Fit the drivebelt by reversing the removal procedure, and release the tensioner to tension the drivebelt.

7 Observe the tensioner indicator, which should be central in its slot (see illustration).
