1 Refer to the Specifications at the beginning of this Chapter and check the tension of each drivebelt at the point stated. Check the full length of each drivebelt for cracks and deterioration. It will be necessary to turn the engine in order to check that portion of the drivebelt in contact with the pulleys. Renew or tension each belt as necessary as follows, according to model type: SOHC models
2 Note that two drivebelts are fitted to models equipped with power steering and both should be renewed if either one is unserviceable. Where fitted, the air conditioning compressor is driven by a separate belt.

3 Disconnect the battery negative lead.

4 Where applicable, remove the air conditioning compressor drivebelt.

5 Loosen the alternator mounting and adjustment nuts and bolts, and pivot the alternator towards the cylinder block.

6 Slip the drivebelt(s) from the alternator, water pump, crankshaft and (where applicable) the power steering pump pulleys.

7 Fit the new drivebelt(s) over the pulleys, then lever the alternator away from the cylinder block until the specified belt tension is achieved. Lever the alternator using a wooden or plastic lever at the pulley end to prevent damage and straining the brackets. It is helpful to partially tighten the adjustment link bolt before tensioning the drivebelt(s).

8 Tighten the alternator mounting and adjustment nuts and bolts in the order shown (see illustration).

9 Where applicable, refit and tension the air conditioning compressor drivebelt.

10 Reconnect the battery negative lead.

11 Drivebelt tension should be rechecked and if necessary adjusted after the engine has been run for a minimum of ten minutes.

DOHC models
12 Three different types of drivebelt arrangement are used, depending on model (see illustrations). On models without power steering, the drivebelt is tensioned by moving the alternator. On models with power steering, the power steering pump is also driven by the coolant pump/alternator drivebelt and an automatic belt tensioner is fitted (see illustration).

On models with air conditioning, the drivebelt drives the alternator, coolant pump, power steering pump and air conditioning compressor, and an automatic belt tensioner is fitted.

13 On models without power steering, loosen the alternator mounting and adjustment bolts, and pivot the alternator towards the cylinder block. Slip the drivebelt from the pulleys.

14 On models with power steering, the automatic tensioner can be released using a 17 mm socket and a wrench on the boss in the centre of the pulley. Lever the tensioner assembly clockwise, slide the belt from the pulleys, then slowly release the tensioner.

15 To fit a new belt on models without power steering, slide the belt over the pulleys, then lever the alternator away from the cylinder block until the correct belt tension is achieved. Lever the alternator using a plastic or wooden lever at the pulley end to prevent damage. It is helpful to partially tighten the adjustment link bolt before tensioning the drivebelt. When the correct tension is achieved, tighten all the bolts.

16 To fit a new belt on models with power steering, lever the tensioner clockwise as during removal, then slide the belt over the pulleys, and slowly release the tensioner.
