       PREVENTIONS
Cars are equipped by safety systems (SRS) including pillows of safety and натяжители seat belts. Before work about gauges of blow, the panel of devices and a steering column disconnect at first negative, and then positive the plug from the storage battery and wait 2 minutes It will exclude unapproved disclosing of pillows of safety and operation натяжителей seat belts which can cause traumas.
Do not suppose hit of a cooling liquid on clothes and a paint and varnish covering of a body. Otherwise wash out a surface a water considerable quantity.
Collect and utilise the merged cooling liquid.
Air central air is under pressure, therefore do not open a central air contour, the coolant is not pumped out yet.
Replacement of a radiator of a heater make, when the engine completely will cool down.

       THE NOTE
Replacement of a radiator of a heater by cars of release since 2001 — very labour-consuming operation for independent performance as demands removal of the panel of devices and the central console and is connected with separation of a considerable quantity of electric sockets.

Removal of a radiator of a heater
Removal on all models. If the car is equipped by air central air, pump out a coolant from a central air contour at servicing deport.
Turn the handle of management in temperature of air submitted to salon of the car, in position HOT (hot).
Merge cooling liquid.
Switch off ignition and disconnect a wire of "weight" from the storage battery.

Fig. 4.24. Places of connection of hoses of giving of a cooling liquid to a heater radiator to tubes on a partition of a motor compartment


In a motor compartment loosen the collars also disconnect hoses of giving of a cooling liquid to a radiator of a heater from pipes on a partition of a motor compartment (fig. 4.24).
Remove sealing rings from the tubes passing through a partition of a motor compartment to a radiator of a heater.
Disconnect pipelines of a central air from the evaporator and remove sealing rings. Close the ends of pipelines plastic stoppers to exclude hit in them of a moisture from air.

On cars of release till 2001. Remove a ware box from the panel of devices. Turn out screws and remove an evaporator casing (fig. 4.25).
Disconnect from the block of a heater an air line of giving of air to feet of back passengers.

Turn away 2 nuts and shift to the right the heater block (fig. 4.26).
Turn out bolts, крепящие the heater pipeline to the top part of the block of a heater, then release a clip and take a heater radiator.

The block of a heater and air central air on cars of release since 2001: 1 – the block of a central air of air; 2 – clips; 3 – hoses of giving of a cooling liquid to a heater radiator; 4 – clips for connection of pipelines of a contour of air-conditioning to the evaporator (Quick Joint); 5 – sealing rings; 6 – consolidation; 7 – the block of the fan of a heater; 8 – an air line of giving of air to feet of back passengers


On cars of release since 2001. Remove the panel of devices and an intensifying beam. Disconnect electric sockets from the engine of the fan and the resistor of the fan and remove the block of the fan of a heater (fig. 4.27).
Remove an air line of giving of air to feet of back passengers.
Turn away 2 nuts and remove the block of a central air of air.
Release clips and remove the thermoresistor and a plait of wires from the block of a central air of air.

Turn out screws and remove a radiator of a heater from the block of a central air of air (fig. 4.29).
Installation of a radiator of a heater
Installation on cars till 2001. Installation make in sequence, return to removal. Fill in cooling liquid.
Fill with a coolant a contour of a central air of air.
Get the engine and check up functioning of systems of heating and an air conditioning.
Installation on cars since 2001. Installation make in sequence, return to removal, taking into account the following.

Fig. 4.30. Thermoresistor installation on an arm (1)


Check up that the thermoresistor established on an arm, acts on 20 mm (fig. 4.30).
Fill in cooling liquid.
Fill with a coolant a contour of a central air of air.
Get the engine and check up functioning of systems of heating and an air conditioning.
