Removal and installation of the block and heat exchanger of a heater

Some of the cars considered in the present manual are equipped with system of additional safety (SRS) 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 getting injured as a result of its casual operation (see. Onboard electric equipment). Isolation and contact sockets of an electrical wiring of a chain of SRS are painted in bright yellow color. It is not necessary to connect any diagnostic units to this chain!

The description of the procedure of removal actually assemblies of the heat exchanger is given below, it should be noted that the procedure of dismantle of a casing of assembly becomes simpler if previously to remove the evaporator of the air conditioning system though it and is connected with need of evacuation of system.

The air conditioning system constantly is under high pressure. Do not disconnect refrigerator lines at all and do not remove any components of system, previously without having executed a discharge of the last. The discharge of the air conditioning system has to be made by forces of the skilled expert in the conditions of a workshop of car service. At a rassoyedineniye of refrigerator lines surely put on goggles!

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

Do not allow hit of antifreeze on open parts of the body and the painted surfaces of the car. Immediately wash away incidentally got splashes a plentiful amount 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 stored in leaky closed container and immediately collect the 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 service. In many regions of the world special points on different reception of working off are equipped. Do not merge old cooling liquid in the sewerage and on the earth at all! Recently nontoxical grades of antifreeze are developed, however they are also subject to utilization in an organized order.

Before starting implementation of the procedure, wait for full 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 you have the correct combination for input of the audio system in action!

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

Forward heater

Details of installation of a forward heater


1. Having asked for the help the expert, discharge To/in and remove the К/В evaporator.
2. In a motive compartment disconnect heating hoses from the heater heat exchanger branch pipes passed through a back partition, remembering their situation (address an illustration above). Push rubber a sealant in salon. At once to a zakuporta the open ends of branch pipes for the purpose of prevention of spraying of cooling liquid at extraction of the heat exchanger.
3. Remove the central console, assembly and an intensifying bar of the dashboard (see the Head Kuzov and Onboard electric equipment).
4. Under the dashboard disconnect air ducts from the heater case.
5. Disconnect cables of management from the heater block, trying not to bend them.
6. Remove a spring clamp of a cable of management that it was possible to manipulate it.
7. Disconnect an electrical wiring from the fan.
8. Give bolts of fastening of the case of a heater to the dashboard and remove the heater case, having pulled it on themselves and down.
9. Prepare enough rags for collecting the spreading cooling liquid.
10. Remove fastenings of the heat exchanger 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 tightening of hose collars. Before installation of the heat exchanger try it compressed air.
12. Adjust each cable so that the course of gates corresponded to the provision of control levers:
   a. Install the handle of management on dashboards in situation FRESH. Lift an adjusting clamp and delay a cable of control of the gate of external air from the case. Release an adjusting clamp;
   b. Install the handle of management on the front panel in position of DEF. Lift an adjusting clamp and move a cable of management towards a heater before receiving the maximum course of the lever. Release an adjusting clamp;
   page. Install the handle of management in the provision of "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 the 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 the illustration Assembly of a Back Heater).
2. Remove front seats.
3. Remove knot of management of a heater (address 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 side overlays, overlays of thresholds of back doors and an overlay of the central rack.
7. Turn off a carpet and remove a conditioner arm.
8. Give a bolt and the screw then remove a heater air duct.
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 an accompanying illustration).
12. Installation – the return procedure. Put on hoses of a heater unions to the second ring-shaped ledge.
