Additional electric fan (installed in front of the cooling system radiator) (Opel Zafira A)

Examination

1. Prepare the car for work (see "Preparing the car for maintenance and repair").

2. Check the serviceability of the electronic unit (see above).

3. Disconnect the electric fan wiring harness connector.



4. For ease of further work, it is better to remove the electric fan. Using a 10 mm wrench, unscrew the two fastening nuts and, tilting the electric fan slightly forward, remove it upwards.



5. Using a thin slotted screwdriver, pry up and remove the protective cover of the additional resistor terminals (shown on a removed electric fan).



6. Connect the brown wire of the electric motor wiring harness to the "ground" and the red wire to the positive terminal of the battery. A 30 A fuse must be cut into the section of wire connecting the red wire to the positive terminal of the battery (see "Checking electrical consumers"). A working electric fan will start working, if it is faulty, the electric fan should be replaced (see below). If the fuse burns out, there is a short circuit in the electric motor and it should also be replaced (see below).



7. If the electric fan is working properly, check the additional resistor (see "Electric cooling fans - checking and replacing the additional resistor").

8. If the additional resistor is OK, then there is a fault in the electrical wiring (see "Checking and repairing electrical circuits").

Replacement

1. Unsolder the electric fan wires from the terminals of the additional resistor.



2. Remove the electric fan wiring harness from the holders on the casing.

3. Using a TORX T15 key, unscrew the three mounting screws and remove the electric motor assembly with the impeller.



4. Install the parts in reverse order.
