5.3.3. Removal and installation of a radiator of the cooling system

Do not start performing procedures before full cooling of the engine.


Models without GUR and K/V

On cars with AT the oil cooler is built in an engine cooling system contour. For removal press oil hoses about a radiator. Close unions and branch pipes traffic jams to exclude an oil effluence. After installation of a radiator fill transmission with oil (see the Head Nastroyki and routine maintenance of the car).


  1. Merge cooling liquid in pure capacity, having disconnected the lower hose from a radiator.
  2. On petrol engines remove an air inlet sleeve.
  3. On X14XE and X16XE engines remove the pump of additional air.
  4. On the diesel engine remove э / the fan motor together with a fan cover.
  5. Separate the electrical wiring socket э / the motor of the fan (1) and a thermoswitch (2).

Conducting sockets э / the motor of the fan (1) and D/In temperatures (2)

  1. Disconnect the top hose of a radiator and a connecting hose going to a broad tank.

  1. Turn out bolts of fastening and disconnect a radiator arm.

  1. Remove a radiator together with the fan from the lower rubber support up.
  2. If the radiator is replaced, rearrange the fan and a thermoswitch on a new radiator.

Features for cars with GUR and K/V


  1. Disconnect an electrical wiring from the second thermoswitch on a radiator.
  2. Remove both thermoswitches from a radiator.
  3. Take aside the GUR liquid tank with the attached hoses.

On l DOHC 1.4 and 1.6 engines carefully disconnect from the pump GUR the line of high pressure so that it could move a little. To make room, incline the line of high pressure towards the engine.

  1. You give bolts of fastening and disconnect the fan case.



  1. After removal from the car the radiator can be checked for existence of signs of leaks, damages and violations of internal passability of the heat exchanger.
  2. Remains of insects and vegetation can be removed from space between heat exchanger plates by blowing by compressed air (do not forget to put on goggles!), or cleaning out by a soft brush. Try not to bend thin plates of the heat exchanger and not to cut about them fingers. Before installation the radiator has to be washed out by giving in water from a garden hose (see the Head Nastroyki and routine maintenance of the car).
  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 sealant (act according to instructions of manufacturers of means). Any more complex repair has to be made only in the conditions of a specialized workshop with use of the necessary equipment.



  1. Installation is made as it should be, the return to an order of dismantle of components. Pay attention to the next moments:
    1. Track correctness of installation of rubber pillows of the lower support of a radiator;
    2. Track correctness of connection and reliability of fixing by fixing collars of all hoses;
    3. In conclusion make gas station the cooling system (see the Head Nastroyki and routine maintenance of the car) and survey of its components on existence of signs of development of leaks.
