Removal and installation of the block and the heater heat exchanger

Some of cars considered in the present Management are equipped by system of additional safety (SRS), more known as a safety pillow. Before to perform any works near to assemblage of a pillow or a steering column, without fail disconnect system in order to avoid reception of traumas as a result of its casual operation (the Onboard electric equipment see). Isolation and contact sockets of electroconducting of chain SRS are painted in bright yellow colour. It is not necessary to connect any diagnostic devices to the given chain!

The description of procedure of removal actually heat exchanger assemblages is more low resulted, it is necessary to notice that procedure of dismantle of a casing of assemblage becomes simpler if preliminary to remove the evaporator of a central air of air though it and is connected with necessity of evacuation of system.

Air central air constantly is under a high pressure. At all do not disconnect refrigerator lines and do not remove any components of system, preliminary without having executed a discharge of last. The discharge of a central air of air should be made by forces of the skilled expert in the conditions of a car-care centre workshop. At рассоединении refrigerator lines necessarily put on goggles!

Manufacturers of cars recommend for the purpose of providing of access to the heater heat exchanger to make full dismantle of the panel of devices and to lower a steering column. The given works are connected with switching-off of set of electric contacts and interfaced to risk of damage of the elements of fixture made of plastic, in a kind of that it will be reasonable to charge their performance to experts of car-care centre.

Do not suppose antifreeze hit on open sites of a body and the painted surfaces of the car. Casually got splashes immediately wash off a plentiful quantity of water. Remember that antifreeze is extremely a toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences (up to a lethal outcome). Never leave antifreeze stored in leaky closed container and immediately collect cooling liquid spilt on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About ways recyclings of the fulfilled cooling liquid consult at any station of car-care centre. In many regions of the world special points on any reception of working off are equipped. At all do not merge an old cooling liquid in the water drain and on the earth! Recently nontoxical grades of antifreeze are developed, however they also are subject to recycling in the organised order.

Before to start procedure performance, wait full cooling of the engine.


1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped by a security code before to disconnect the battery make sure that have a correct combination for audiosystem input in action!

2. Having waited definitive cooling of the engine, empty cooling system (see the Head of Adjustment and car routine maintenance).

Forward heater

Details of installation of a forward heater


1. Having addressed for the help to the expert, discharge К/В and remove evaporator K/V.
2. In an impellent compartment disconnect heating hoses from the branch pipes of the heat exchanger of a heater passed through a back partition, remembering their position (address to an illustration above). Push rubber уплотнители in salon. At once закупорьте the open ends of branch pipes for the purpose of prevention разбрызгивания a cooling liquid at heat exchanger extraction.
3. Remove the central console, assemblage and an intensifying bar of the panel of devices (the Body and the Onboard electric equipment see the Head).
4. Under the panel of devices disconnect from the case of a heater air lines.
5. Disconnect from the block of a heater management cables, trying not to bend them.
6. Remove a spring clamp of a cable of management that it was possible for them to manipulate.
7. Disconnect from the fan electroconducting.
8. Give bolts of fastening of the case of a heater to the panel of devices and remove the heater case, having pulled it on itself and downwards.
9. Prepare enough rags for gathering of a spreading cooling liquid.
10. Remove heat exchanger fastenings to the case, remove overlays and collars. Take out the heat exchanger from the case upwards.
11. Assemblage is made upside-down. Track reliability of a tightening шланговых collars. Before heat exchanger installation try its compressed air.
12. Adjust each cable so that the course заслонок corresponded to position of control levers:
   a. Establish the management handle on the panel of devices in position FRESH. Lift an adjusting clamp and delay from the case a management cable заслонкой external air. Release an adjusting clamp;
   b. Establish the management handle on the obverse panel in position DEF. Lift an adjusting clamp and move a cable of management towards a heater before reception of the maximum course of the lever. Release an adjusting clamp;
   With. Establish the management handle in position «COOL». Lift an adjusting clamp and move a management cable демпфером mixing of air towards the heater case to receive the maximum course of the lever.
13. Fill cooling system, connect the battery and start the engine. Make sure of absence of signs of development of leaks, estimate serviceability of functioning of system of heating.

Back heater

Assemblage of a back heater

Details of installation of a back heater


1. Disconnect hoses from heater branch pipes (address to an illustration Assemblage of a back heater).
2. Remove forward seats.
3. Remove knot of management of a heater (address to an illustration of the Detail of installation of a back heater).
4. Remove the back console and a cover of the forward console.
5. Remove a back overlay in the bottom part of the central console.
6. Remove overlays of a threshold at a forward door, forward lateral overlays, overlays of thresholds of back doors and an overlay of the central rack.
7. Turn away a carpet and remove a conditioner arm.
8. Give a bolt and the screw then remove a heater air line.
9. Disconnect a socket of conducting of the fan.
10. Give bolts of fastening of the block of a heater and remove the heater block, trying not to spill cooling liquid in salon.
11. Remove fastenings and take out the heat exchanger of a heater from the block (address to an accompanying illustration).
12. Installation – return procedure. Heater hoses put on unions to the second кольцеобразного a ledge.
