Radiator and fan
GENERAL INFORMATION

Check of a radiator and radiator stopper

Check on tightness of a stopper of a broad tank Check of system of cooling on tightness

The system of cooling works under pressure. The stopper of a broad tank is under the influence of effort of a spring which opens and closes system at achievement in it a certain pressure.
The increase in pressure of cooling liquid leads to increase of a point of its boiling.
The special pump is necessary for check of a stopper of a radiator. The pump wells up on a stopper and pressure is created until the valve will open. It should occur within specified above pressure. If it does not occur, the stopper is subject to replacement. The pump and its installation are shown on иллюстр. By means of the same pump the system of cooling can be checked on tightness. Pump installation on a broad tank in this case is shown on иллюстр. At the engine of 2.4 l the broad tank has the form shown on иллюстр. "The broad tank of the engine of 2.4 l", however check is made similarly. Create pressure in 1¬ú/cm3 and check, that the manometer held this pressure within not less than 2 minutes. If pressure does not keep, the system has a leak. At operation by the pump it is necessary to be guided by instructions of his manufacturer.

Removal and radiator installation

Before radiator or fan removal previously disconnect the storage battery as at the included ignition feeding wires of the fan are energized. The fan acts in film as follows:

PERFORMANCE ORDER
1. Merge liquid from system as it is described in the Section Filling of a cooler of system of cooling of Head the Current leaving and service. Unscrew a stopper of a broad tank to facilitate a liquid exit. Collect liquid in capacity if it is used further. Otherwise utilize it as appropriate.
2. Rasstykuyte shtekerny connections of the thermostat and fan.
3. Weaken collars of fastening of hoses on a radiator and remove hoses. Take hoses aside, without bending them.
4. At the car till 1993 of release with the engine of 2.0 l remove facing of the fan and hang up it on the fan.
5. Disconnect radiator fastening in the top part. The radiator fastens corners with left and on the right side and bolts in the center. Take out a radiator on the top of, at cars till 1993 of release together with facing. Thus watch to damaging tubes.

At installation of a new radiator it is necessary to establish also new elements of its fastening.
Instruction

At the DOHC engine it is necessary to disconnect hoses from the resonator of soaking-up air. Besides, before sjemy a radiator it is necessary to remove the case of the engine of the fan. Details of this engine are shown on иллюстр. point 5 (Removal and radiator installation).
Installation of a radiator is carried out in sequence, return to its removal. Fill system with liquid as it is described in the Section Filling of a cooler of system of cooling of Head the Current leaving and service.

Replacement of the fan of cooling

DOHC ENGINE

The details which are subject to removal, are shown on иллюстр. point 5 (Removal and radiator installation).

PERFORMANCE ORDER
1. Rasstykuyte shtekerny connection of the electric motor.
2. Remove a radiator as it is described in appropriate section.
3. Unscrew bolts of fastening of a radiator (иллюстр.).
4. Unscrew the nuts (1) shown on иллюстр., also remove the fan case.
5. Remove a lock ring on an electric motor shaft. Remove knot of the ashkey.

Installation of the fan is carried out in sequence, return to its removal. On an electric motor shaft the krylchatka fastens a lock ring.
After installation of a radiator and system filling with liquid start the engine and check operation of the fan.

THE ENGINE OF 2.0 L OF OHC TILL THE END OF 1996. RELEASE (INCLUDING THE VYAZKOSTNY COUPLING)

At this engine the fan of cooling acts in film together with the vyazkostny coupling.

PERFORMANCE ORDER
1. Disconnect a weight cable from the storage battery.
2. Remove maple a belt as it is described in appropriate section.
3. Turn out the central bolt from the fan. The bolt is shown on иллюстр., it has the left carving. At a bolt otvorachivaniye the krylchatka should keep from a provorachivaniye.
4. Remove the vyazkostny coupling and a pulley.

Installation of the fan is carried out in sequence, return to its removal. A bolt tighten the moment of 26 Nanometers (the left carving!).

THE ENGINE OF 2.4 L (INCLUDING THE VYAZKOSTNY COUPLING)

At this engine the fan of cooling acts in film together with the vyazkostny coupling.

PERFORMANCE ORDER
1. Disconnect a weight cable from the storage battery.
2. Remove maple a belt as it is described in appropriate section.
3. Turn out the central bolt from the fan. The bolt is shown on иллюстр., it has the left carving.
4. Remove the vyazkostny coupling and a pulley.

Installation of the fan is carried out in sequence, return to its removal. A bolt tighten the moment of 26 Nanometers (the left carving!).

THE ENGINE OF 2.0 L OF OHC OF RELEASE SINCE 1997.

At this engine bolts turn away and all frame of the fan from the interior of a radiator acts in film. The fan further acts in film.

PERFORMANCE ORDER
1. Disconnect a weight cable from the storage battery and расстыкуйте shtekerny connection at the fan electric motor.
2. Remove the fan as it was already described.
3. Unscrew bolts (1) and (2) from the interior of a radiator (иллюстр.) also take out all case of the fan from the bottom arms.
4. Unscrew three nuts from the interior of the electric motor (see иллюстр.) also remove the case.
5. Remove with a screw-driver a lock ring from a shaft of the electric motor of the fan and disassemble knot.

Assembly of the fan is carried out in sequence, return dismantling.
