Removal, check of a state and installation of a radiator

Cooling system radiator

1 — the Hose of a supply of cooling liquid from the engine
2 — the Hose of a supply of cooling liquid from a broad tank
3 — the Branch pipe of a supply of cooling liquid from the thermostat case
4 — the Branch pipe of a supply of cooling liquid from a broad tank
5 — the Opening under installation termochuvstvi-
telny sensor switch

6 — the Thermosensitive sensor switch
7 — the Branch pipe of removal of cooling liquid
8 — the Hose of removal of cooling liquid
9 — Rubber pillows of support


Cooling system radiator - general information

Models of 1.3 l

 PERFORMANCE ORDER

1. The radiator of tubular type with a horizontal stream of cooling liquid which is released according to the license of the French company Sofica is installed in the cooling system of the engine of the considered models of cars. The general view of a radiator is presented on an illustration.
2. The heat exchanger of a radiator represents a set of horizontally located aluminum tubes connected by both ends to plastic side capacities. Connections are executed by a press fitting method, and places of joints are pressurized by means of the rubber laying put on special paste.
3. In the lower part of the right side capacity the branch pipe of removal of cooling liquid from a radiator is located, and over it the opening under landing of the thermosensitive sensor switch is provided.
4. In the top part of the left side capacity there is a branch pipe of a supply of cooling liquid, under it - the branch pipe connecting a radiator to a broad tank.
5. The bases of both side capacities through rubber pillows the radiator leans on a cross beam of a front of the car.
6. The upper edge of a radiator two bolts of M6x12 fastens to the top cross beam of a front.
7. Thanks to the applied materials the radiator has insignificant weight and has big external and internal corrosion stability in comparison with radiators of traditional type. At manufacturer all radiators without fail are subjected to tests for tightness for what in the heat exchanger compressed air which pressure exceeds operational values moves.


Models of 1.6 l without air conditioning system

 PERFORMANCE ORDER

On the models without To/in equipped with the engine of 1.6 l the radiator of production of the Autopal company of the increased size (285х590) is used. Both branch pipes are on the left side of a radiator, liquid moves in the horizontal direction.


Diesel models without To/in and petrol models of 1.6 l with To/in

 PERFORMANCE ORDER

1. On these models the radiator of production of ML3 AKG with dimensions 322х590 and tubes of oval section is used. The radiator is two-row, with a horizontal stream of liquid.
2. The scheme of fastening of a radiator is a little changed: inflows which rubber pillows are put on are provided in the lower part. Then the radiator refuels in body openings. From above two plastic clips with M6 bolts are provided.

REMOVAL

 PERFORMANCE ORDER

If removal of a radiator is made for the purpose of identification of a source of leak, remember that small thinnesses in situ with use of special radiator sealant can be eliminated.

Disconnect a negative wire from the battery, then empty the cooling system.


Petrol models

 PERFORMANCE ORDER

1. Release fixing collars and...

... disconnect the top and lower hoses from a radiator. On models of 1.3 l also disconnect a hose of a broad tank.

2. Disunite sockets of an electrical wiring of the driving motor and the sensor switch of the fan of the cooling system. Release an electrical wiring from clamps on the case of a radiator and a casing of the fan.

3. Turn out bolts of fastening of a radiator to the top cross beam of a front of the car (in this beam the cowl lock latch is built in).

4. Having removed from the lower support, take a radiator from a motive compartment...

... try not to lose rubber pillows of the lower support.

On some models for the purpose of providing sufficient working space it is necessary to otboltit and remove the intensifying bar connecting the top cross beam of a front to a forward skirt.


Diesel models

 PERFORMANCE ORDER

1. Release a collar and disconnect the top hose from a radiator.
2. Turn out a fastening bolt on the arm of a cooling tube of the lower hose. Release a collar, disconnect a tube from a hose of a casing of the thermostat and take it from a motive compartment.
3. Remove assembly of the fan of the cooling system (see the Section Check of Serviceability of Functioning, removal, installation, dismantling and assembly of the fan of the cooling system).
4. Disconnect an electrical wiring from the cooling system fan sensor switch screwed in a radiator.
5. On the models equipped with system of hydrostrengthening of a wheel you otboltit the tank of hydraulic liquid from a cross beam and move away him from a radiator aside. In order to avoid spraying of liquid try not to incline the tank excessively.
6. Turn out bolts of fastening of a radiator to the top cross beam of a front of the car (with a cowl lock latch).
7. Remove a radiator from the lower support and take it from a motive compartment. At once remove rubber pillows of the lower support.


Check of a state


 PERFORMANCE ORDER

1. If suspicion of violation of passability of its heat exchanger became the reason of removal of a radiator, it is necessary to make its obratnopotochny washing. A soft brush (do not cut fingers about edges of plates) clean gaps between radiator heat exchanger plates. In the presence of access to a source of compressed air, blow gaps (do not forget to put on goggles).

Remember that fragile plates of the heat exchanger of a radiator at careless handling easily can be damaged!

2. In case of need at car repair shop it is possible to make "flowing" check of a radiator on existence of blocking of internal channels.
3. Repair of the radiator which lost tightness should be carried out only in the conditions of a specialized workshop. Attempts to correct a situation by means of a soldering iron will lead only to damage of plastic components.
4. In an extreme situation insignificant leak of cooling liquid from a radiator can be suspended by means of special sealant without extraction of a radiator from the car (in situ). Follow instructions for use of sealant.
5. Before sending of a radiator in repair shop remove from it the fan sensor switch.
6. Check a condition of rubber pillows of support of a radiator. In case of need make replacement.

INSTALLATION

 PERFORMANCE ORDER

Installation is made as it should be, the return to a dismantle order. Pay special attention to the next moments:

a) Track correctness of gearing of a radiator in assemblies of the lower support. Strongly tighten fixing bolts.
b) Track correctness of connection and reliability of fastening by collars of all hoses.
c) In conclusion do not forget to make gas station of the cooling system.
