Removal and installation of a radiator and expanded tank of system of cooling

Do not start performance of procedures before complete cooling of the engine. See also preventions at the beginning of the Section Antifreeze - general information.

Broad tank


1. On models 1993 and 1994 of вып. the broad tank is located in the left corner of an impellent compartment and fixed near the battery. Since 1995 the tank is transferred on the opposite side of an impellent compartment, - to the right forward corner.

2. Disconnect a hose from the top part of a radiator and press it. On models 1993 and 1994 of вып. turn out a fixing bolt and remove a broad tank. On models since 1995 вып. the tank is simply vertically extended from a basic arm.

3. Merge cooling liquid in specially prepared capacity.
4. By means of bottle ершика wash out a tank outside and from within, then attentively examine it on existence of cracks and other mechanical damages. In case of detection of defects, and also at impossibility of reading of level of liquid through translucent walls, a tank is subject to replacement.

At all do not apply ершик, used when cleaning a broad tank to washing of drinking ware!

5. Installation is made upside-down.



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. Cock the parking brake and prop up protivootkatny boots back wheels. To Poddomkratta a car front also establish it on props.
3. Empty cooling system (see. Head of Control and routine maintenance). If replacement of cooling liquid was made recently, keep for further use (see the prevention in the Section Antifreeze - general information).

4. The scheme of installation of a radiator in an impellent compartment is provided on an illustration.

5. On models from AT disconnect from a radiator of the line of a path of cooling of ATF. Prepare for collecting spilled liquid, at once закупорьте the open ends of tubes and unions.

6. Release collars and disconnect from a radiator both (top and bottom) hoses. If hoses "became attached" to connecting branch pipes, use nippers, or a knife (with the subsequent replacement of hoses). Try not to damage connecting branch pipes. Also disconnect from a radiator thin perelivny a hose going to a broad tank.
7. Remove the fan (ы) cooling systems (see. Section Check of a condition of fans of system of cooling and chains of their inclusion; replacement of components).

8. To Otboltita small arms of fastening of a radiator to the top basic beam.

9. Take radiator assembly from an impellent compartment. Be careful, - do not cut fingers about keen edges of plates of the heat exchanger, try not to spill cooling liquid on the painted body surfaces.
10. After removal from the car the radiator can be checked on existence of signs of leaks, damages and violations of internal passableness of the heat exchanger. Any repair should be made only in the conditions of a specialized workshop with use of the necessary equipment.
11. Remains of insects and vegetation can be removed from space between heat exchanger plates a way of blowing by the compressed air (do not forget to put on goggles!), or vychishcheniye soft brush. Try not to bend thin plates of the heat exchanger and not to cut about them fingers. Before installation the radiator should be washed out by a giving way in water by means of a garden hose.
12. Check a condition of rubber support of a radiator, in case of need make replacement of the failed components.
13. Installation is made upside-down. Track correctness of placement of a radiator on the support.
14. On completion of installation fill in in system cooling liquid of demanded structure, let out from a path air jams (see. Head of Control and routine maintenance).
15. Start the engine and check it on existence of signs of leaks. Warm up the engine to normal working temperature (both hoses of a radiator should become hot to the touch). Check level of cooling liquid, in case of need add the corresponding quantity of a mix of demanded structure.
16. On models from AT check ATF level, in case of need execute the corresponding adjustment.
