Removal and installation of a radiator of system of cooling

Attention: Any work on maintenance or repair of the cooling system should be carried out on a cold engine! See also safety precautions in Section 2.

Based on the operation to remove the radiator on models with engines Z10XE (P) /Z14XE without air conditioning. For other engines, only additional operations or features of this procedure.

Z10XE engine (P) /Z14XE (without air conditioning)

Removing

1. Disconnect the battery (see chapter 5).

2. Drain the coolant (see Section 3), on Corsa-Eco models, remove the crankcase guard (see chapter 2).

3. Remove the front bumper (see chapter 11).

4. Remove the air intake of the air supply system (see illustration 6.3)

5. Loosen the mounting clamps and disconnect the lower cooling system hose from the radiator.

6. Having unscrewed the mounting bolts, remove the 2 upper radiator holders (see resist. illustration).



7. Loosen the clamps, disconnect the overflow hose from the radiator and disconnect the connector of the electrical wiring of the electric motor of the cooling fan.


8. Carefully remove the radiator from the engine compartment down, unscrew the fixing bolts (see resist. illustration) and remove the fan assembly from the heatsink.

Examination

9. Once removed from the vehicle, the radiator can be inspected for signs of leaks, damage, or abnormalities in the internal patency of the heat exchanger.

10. The remains of insects and vegetation can be removed from the space between the heat exchanger plates by blowing with compressed air (don't forget to wear safety goggles!), or scrubbing with a soft brush. Take care not to bend the thin heat exchanger plates or cut your fingers on them. If necessary, before installation, the radiator can be flushed by introducing water from a garden hose into the interior (see Section 5).

11. Check the condition of the supports and holders of the radiator, if necessary, replace the failed components.

12. Sources of small leaks can be sealed with a suitable sealant (act in accordance with the manufacturer's instructions).

Attention: Before using the sealant, consult with Opel representatives about the possibility of using it for the cooling system of a particular model! Any more complex repairs should be carried out only in a specialized workshop using the necessary equipment.

Installation

13. If the radiator is being replaced, reinstall all attachments from the old one onto the new radiator and install the fan assembly.

14. Installation is carried out in the reverse order to the dismantling of the components. After completion of work, fill the cooling system (see Section 3), remove the air and make sure the system is tight (see Section 5).

Features of models with air conditioning

Note: On the Z17DTH engine, to remove the fan, you will need to open the coolant circuit of the A/C system - contact a service station where there is equipment specially designed for this purpose and trained personnel.

15. Remove the fan housing mounting bracket from below.

16. Turn out 2 bolts of fastening (see resist. illustration) and remove the capacitor from the holder. Secure the capacitor with wire to the motor.

Attention: The refrigerant circuit is not opened!

17. Have an assistant hold the radiator. Turn out 4 bolts and remove 2 lower holders of a radiator. With the help of an assistant, carefully remove the radiator from the engine compartment down (see resist. illustration).

Features of Z12XE/Z14XEP engines

Note: On models not equipped with an A/C system, the front bumper does not need to be removed.

18. Remove the cooling fan (see Section 6).

19. Carefully remove the radiator from the rubber supports upwards.

Features of the Z18XE engine

20. Remove the klaxon horn (see chapter 12).

Features of Meriva models

21. Remove the front bumper (see chapter 11).

22. Turn out bolts of fastening and remove the top and bottom holders of a radiator.

23. Use the help of an assistant and carefully remove the radiator together with the fan assembly from the engine compartment down.
