Removal and installation of a radiator of system of cooling

Do not start performance of procedures before complete cooling of the engine. See also preventions at the beginning of the section Antifreeze - general information.

Removal

Petrol models

 PERFORMANCE ORDER

  1. On models without the conditioner of air disconnect a negative wire from the battery (see. Head engine Electric equipment).
  2. On the models equipped with central air, remove the battery with a basic arm (see. Head engine Electric equipment). Also remove air purifier assembly with air lines.
  1. On equipped In the Zafira models turn out fixing bolts, uncover front panels.
  1. Separate the inlet resonator from a cover and from a sleeve of an inlet air line.
  1. Cock the parking brake. To Poddomkratta the car also establish it on props. At the corresponding complete set remove protection of a case.
  2. Empty cooling system (see. Head Routine maintenance).
  3. Remove the fan in collecting (see. Check of serviceability of functioning, removal and installation of the fan of system of cooling).
  1. Weaken a fixing collar and disconnect brought to a radiator on the right the top hose.
  1. Disconnect the bottom hose (it is brought to a radiator at the left).
  1. Also disconnect a hose of a broad tank on the left side of a radiator.
  1. On models from AT turn out fixing bolts and disconnect from the left tank of a radiator hoses of cooling of ATF. Remove copper sealing washers, - prepare for collecting spilled liquid (establish under branch pipes suitable drain capacities). Try to remember an order of connection of all hoses.
  2. Remove a front bumper (see. Head Body).
  3. For the purpose of radiator fixing during removal of arms of the bottom support, operating from an impellent compartment, pass two welding electrodes or two screw-drivers in lateral fastenings of a radiator.
  4. Turn out fixing bolts and separate from a radiator arms of the bottom support of fastening of assembly to a stretcher, - arms act in film assembled with rubber pillows.
  5. On the models equipped with central air of air, turn out bolts of fastening of the condenser of the conditioner to a forward part of a radiator, then tie up the condenser to the front panel, - do not disunite the line of a refrigerator path!
  1. Holding a radiator, take elements fixing it (screw-drivers or electrodes), then, having shifted down, liberate a radiator from support and take it from an impellent compartment.
  1. In case of need rearrange on a new radiator hinged elements.

Diesel models

 PERFORMANCE ORDER

  1. Cock the parking brake. To Poddomkratta the car also establish it on props. At the corresponding complete set remove protection of a case.
  2. On models with DOHC engines, remove the storage battery with a basic arm (see. Head engine Electric equipment), - do not forget to turn out a fastening bolt to an arm of a plait of electroconducting.
  3. Remove a front bumper (see. Head Body).
  4. On models with Y20DTH engines remove the dempferny block established under a bumper. Also remove assembly of an interkuler (see. Head of the Power supply system and release).
  5. Remove a protective casing of the engine, then, on models of 1.7 l, remove from a back part of a radiator ventilyatorny assembly (see. Check of serviceability of functioning, removal and installation of the fan of system of cooling).
  6. Remove an air purifier, an inlet air line and the sensor of a measuring instrument of weight of air (see. Head of the Power supply system and release).
  7. On the models equipped with central air of air, disconnect electroconducting from the To/in compressor, a receiver/dehumidifier, the additional fan and the control unit of the fan of system of cooling. Disconnect from a body element the tire of grounding and take all conducting aside.
  8. empty cooling system (see. Head Routine maintenance).
  9. Disconnect from a radiator the top and bottom hoses. Disconnect a purge hose.
  10. For the purpose of radiator fixing during removal of arms of the bottom support, operating from an impellent compartment, pass two welding electrodes or two screw-drivers in lateral fastenings of a radiator.
  11. Turn out fixing bolts and separate from a radiator arms of the bottom support of fastening of assembly to a stretcher, - arms act in film assembled with rubber pillows.
  12. On the models equipped with central air of air, turn out bolts of fastening of the condenser of the conditioner to a forward part of a radiator, then tie up the condenser to the front panel, - do not disunite the line of a refrigerator path! Turn out bolts of fastening of a basic arm of an interkuler.
  13. Holding a radiator, take elements fixing it (screw-drivers or electrodes), then, having shifted down, liberate a radiator from support and take it from an impellent compartment.
  14. In case of need rearrange on a new radiator hinged elements (the fan of system of cooling and an interkuler).

Check

 PERFORMANCE ORDER

  1. After removal from the car the radiator can be checked on existence of signs of leaks, damages and violations of internal passableness of the heat exchanger.
  2. Remains of insects and vegetation can be removed from space between heat exchanger plates a way of blowing by the compressed air (do not forget to put on goggles!), or vychishcheniye soft brush. Try not to bend thin plates of the heat exchanger and not to cut about them fingers. Before installation the radiator should be washed out by a giving way in water from a garden hose (see. Head Routine maintenance).
  3. Check a condition of rubber support of a radiator, in case of need make replacement of the failed components.
  4. Sources of small leaks can be closed up by means of suitable hermetic (act according to instructions of manufacturers of means). Any more difficult repair should be made only in the conditions of a specialized workshop with use of the necessary equipment.

Installation
