Removal and installation of the block and heater heat exchanger

Some from cars considered in the real Management are equipped with system of the additional safety (SRS) which is better known as a safety cushion. Before performing any works near assembly of a pillow or a steering column, without fail disconnect system in order to avoid receiving traumas as a result of its casual operation (see. Onboard electric equipment). Isolation and contact sockets of electroconducting of a chain of SRS are painted in bright yellow color. It is not necessary to connect any diagnostic devices to this chain!

Below the description of procedure of removal actually heat exchanger assemblies is provided, it should be noted that procedure of dismantle of a casing of assembly becomes simpler if previously to remove the evaporator of central air of air though it and is connected with need 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, previously without having executed a discharge of the last. The discharge of central air of air should be made by strengths of the skilled expert in the conditions of a car-care center workshop. At a rassoyedineniye of refrigerator lines surely put on goggles!

Manufacturers of cars recommend for the purpose of ensuring access to the heat exchanger of a heater to make complete dismantle of the dashboard and to lower a steering column. These works are connected with shutdown of a set of electric contacts and interfaced to risk of damage of the elements of fixture made of plastic, in a type of that it will be reasonable to charge their performance to specialists of car-care center.

Do not allow antifreeze hit on open sites of a body and the painted surfaces of the car. Casually got splashes immediately wash away a plentiful quantity of water. Remember that antifreeze is extremely 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 being stored in leaky closed container and immediately collect cooling liquid spilled on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About ways utilization of the fulfilled cooling liquid consult at any station of car-care center. In many regions of the world special points on different reception of working off are equipped. At all do not merge old cooling liquid in the sewerage and on the earth! Recently nontoxical grades of antifreeze are developed, however they also are subject to utilization in the organized order.

Before starting procedure performance, wait complete cooling of the engine.


1. Disconnect a negative wire from the battery.

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

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

Forward heater

Details of installation of a forward heater


1. Having addressed for the help to the expert, discharge To/in and remove the К/В evaporator.
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 situation (address to an illustration above). Push rubber a sealant in salon. At once закупорьте the open ends of branch pipes for the purpose of prevention of a razbryzgivaniye of cooling liquid at heat exchanger extraction.
3. Remove the central console, assembly and an intensifying bar of the dashboard (see. Head Body and Onboard electric equipment).
4. Under the dashboard disconnect from the heater case air lines.
5. Disconnect from the heater block 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 dashboard and remove the heater case, having pulled it on itself and down.
9. Prepare enough rags for collecting spreading cooling liquid.
10. Remove heat exchanger fastenings to the case, remove slips and collars. Take out the heat exchanger from the case up.
11. Assembly is made upside-down. Track reliability of a tightening of shlangovy collars. Before installation of the heat exchanger try it the compressed air.
12. Adjust each cable so that the course a zaslonok corresponded to the provision of control levers:
   a. Establish the management handle on the dashboard in the situation FRESH. Lift an adjusting clamp and delay from the case a cable of management of a zaslonka of external air. Release an adjusting clamp;
   b. Establish the management handle on the obverse panel in the situation DEF. Lift an adjusting clamp and move a management cable towards a heater before receiving the maximum course of the lever. Release an adjusting clamp;
   page. Establish the management handle in the situation "COOL". Lift an adjusting clamp and move a cable of management of a damper of 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 lack of signs of development of leaks, estimate serviceability of functioning of system of heating.

Back heater

Assembly of a back heater

Details of installation of a back heater


1. Disconnect hoses from heater branch pipes (address to an illustration Assembly 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 slip in the lower part of the central console.
6. Remove overlays of a threshold at a forward door, forward lateral slips, overlays of thresholds of back doors and an overlay of the central rack.
7. Unscrew a carpet and remove a conditioner arm.
8. Give a bolt and the screw then remove a heater air line.
9. Disconnect the 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 heater heat exchanger from the block (address to an accompanying illustration).
12. Installation – return procedure. Hoses of a heater put on unions to the second ring-shaped ledge.
