Check of serviceability of functioning, removal and installation of the fan of system of cooling

At the hot engine the fan of system of cooling can be activated at any moment, - observe extreme care!

Check

The electric fan receives a food from the storage battery. The structure of an electric contour of the fan includes a protective safety lock, the ignition and relay switch (see. Head Onboard electric equipment). Control of functioning of the fan carries out the electronic control unit which is guided by data, temperatures of cooling liquid arriving from the sensor. The control unit is located at the left under a forward spoiler, behind a front bumper.


 PERFORMANCE ORDER

  1. For check of serviceability of functioning of the fan start the engine and warm up it on single turns to normal working temperature. The fan should work before the arrow of the index of temperature of the engine on the dashboard of the car will come nearer to sector of an overheat of the dial. If operation of the fan does not occur, check serviceability of giving of supply voltage on the corresponding wire of the fan and the relay (see. Head Onboard electric equipment). Refusal of giving of a food can result from knocking-out of a safety lock, failure of the switch of ignition, malfunction of the relay or electroconducting damage. The probability of failure of the driving electromotor of the fan is not excluded also.

Removal

Petrol models

The Astra models without air central air

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery (see. Head engine Electric equipment) also take him aside from the polar plug.
  2. Disunite the contact socket of electroconducting of the fan and liberate a plait of wires from intermediate clamps.
  1. Turn out the top bolts of fastening of the fan to a radiator.

    1 — the Top fixing bolts
    2 — the Bottom support

  1. Accurately lift an impellent compartment.
  2. Transfer the fan on a workbench, turn out the fixing screw, disunite the contact socket and remove from a frame the preliminary resistor.
  1. Turn out fixing screws (1) and remove from a frame of ventilyatorny assembly the driving electromotor and a krylchatka.
  1. In case of need give screws (2) and separate a krylchatka from the motor.

The Zafira models without air central air

 PERFORMANCE ORDER

  1. Remove a front bumper (see. Head Body).
  2. Disconnect from the fan electroconducting and liberate it from intermediate clamps.
  3. Turn out lateral bolts and, having omitted ventilyatorny assembly, carefully take it from an impellent compartment.
  4. Transfer the fan on a workbench, release clamps and remove a diffuzor, turn out three fixing bolts and remove a krylchatka. Turn out the fixing screw, disunite the contact socket and remove from a frame the preliminary resistor. In case of need release fixture and remove the electromotor.

The Astra models with air central air

 PERFORMANCE ORDER

  1. Remove the storage battery with a basic arm.
  2. Remove air purifier assembly with an air line (see. Head of the Power supply system and release).
  3. Remove a front bumper (see. Head Body).
  4. Empty cooling system (see. Head Routine maintenance).
  5. Disconnect electroconducting of the fan, the pressure and compressor K/century sensor also disunite the back socket from the module of management of system of the cooling located at the left under a forward spoiler. Give a fixing nut and disconnect from a mudguard the grounding tire.
  6. Disconnect from a radiator the top and bottom hoses.
  1. Turn out the top bolts of fastening of the fan to a radiator.

    1 — the Top fixing bolts
    2 — the Bottom support

  1. Lifting, carefully liberate ventilyatorny assembly the fan from the bottom support and take it from an impellent compartment.
  2. Transfer the fan on a workbench, turn out the fixing screw, disunite the contact socket and remove from a frame the preliminary resistor.
  1. Turn out fixing screws (1) and remove from a frame of ventilyatorny assembly the driving electromotor and a krylchatka.
  1. In case of need give screws (2) and separate a krylchatka from the motor.

The Zafira models with air central air

 PERFORMANCE ORDER

  1. Remove air purifier assembly with an air line (see. Head of the Power supply system and release). Disconnect electroconducting from a measuring instrument of weight of air (see. Head of the Power supply system and release).
  2. Release fixing a collar and disconnect a hose of ventilation of a case from a cover of the gas-distributing mechanism.
  3. Having turned out bolts and having released clamps, remove from the front panel the air resonator.
  4. Remove a front bumper (see. Head Body).
  1. Disconnect from the fan electroconducting and liberate it from intermediate clamps.
  1. Turn out fixing boats and take ventilyatorny assembly from an impellent compartment.
