Generator Drive Belt — Removal, Installation and Tensioning (Opel Astra F)

Disconnect the air lines from the air cleaner and from the air box or throttle body where required and remove them for better access.

On 1.4L and 1.6L models equipped with power steering, the alternator drive belt also drives the power steering pump.

To remove the belt on 1.8L and 2.0L models, first remove the power steering pump drive belt as directed in chapter 10.

Loosen the alternator nuts and bolts enough to allow the alternator to be rotated toward the engine.

Remove the belt from the pulleys.

Install the belt on the pulleys and tighten the belt gradually by turning the generator away from the engine and lightly tightening the nuts and bolts.

On 1.8L and 2.0L engine models, install and tension the power steering pump drive belt as shown in chapter 10.

Tighten the alternator drive belt as shown below.

Proper tension of the drive belt ensures its long service life. However, try not to overtighten the belt, as this leads to increased wear of the generator.

Follow the steps in the first two paragraphs of this section.

Although checking the drive belt tension requires special tools, the tension can also be checked approximately by pressing down on the middle of the belt with your thumb - there should be about 13 mm of deflection.

Install air ducts.

After installing a new belt, you should check its tension after driving approximately 400 km.
