Starter — removal, installation and repair (Opel Frontera A)

Bosch starter assembly diagram

As stated above, the starter has a forced movement of the engine drive gear by means of an electromagnetic traction relay.

The car is usually equipped with a Bosch starter. A Delco-Remy starter can also be installed.

Checking the starter

Check whether the battery is charged and whether the battery terminals have an oxide film. This is especially true for the ground terminal if it is not tightened tightly enough.

To test the starter at full battery voltage, connect terminals "30" (big terminal) and "50" (small terminal next to big one) cable with a cross-section of at least 4.0 mm². If the starter now works perfectly, the wires to the starter should be checked. If the starter does not turn, it should be removed and checked.



A precise check is carried out on a test bench or in an electrical workshop.

Removal and installation the starter

Disconnect the ground cable from the battery.

1. Raise and support the front of the vehicle on stands.

2. Before disconnecting the cables from the starter, you must remember the order in which they are connected. Disconnect the positive battery cable from the starter terminal and then both cables from terminals 16 and 50. If it interferes, disconnect the lower steel sheet.

3. Now you can remove the starter. Its fastening may vary for different engine versions. Bolts can be inserted from the engine or gearbox side. A support bracket can also be used.

4. Remove the starter by turning it around.

The starter is installed in the reverse order of removal. Different tightening moments must be taken into account. Tighten the engine side mounting bolts to 45 Nm, and the gearbox side bolt to 75 Nm. Starter support (if it exists) tightened to a torque of 25 Nm to the cylinder block and to a torque of 7 Nm to the starter.

Starter repair

If the generator check shows that the fault is inside the generator, then it must be sent to a specialized workshop for repair. If you have experience, you can disassemble and assemble the starter yourself in accordance with the illustration.

The starter brushes wear out as a result of long-term use and can be replaced independently. To do this, the rear part of the starter is opened (remove the small cover, unscrew the bolts and remove the manifold) and the brushes are taken out.
