Coolant pump/alternator drivebelt tensioner (DOHC models with power steering) - removal and refitting
Removal
1 Remove the alternator drivebelt.
2 Loosen the alternator lower mounting through-bolt, then remove the alternator upper mounting bolt and swing the alternator away from the engine.
3 Unscrew the central securing bolt, and withdraw the drivebelt tensioner assembly (see illustration).

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).
