5.4. Radiator

Removal, service and repair
The radiator serves for liquid cooling with a stream of the air passing through a radiator core. The core of a radiator consists of aluminum tubes and the aluminum cooling plates. For increase in efficiency of cooling of liquid of a plate are stamped with the notch providing whirl of air through a radiator.

PREVENTION
You make replacement of a radiator on the cold engine. Besides, when carrying out any works near the fan for prevention of its any inclusion it is necessary to disconnect a wire from the negative plug of the rechargeable battery.

Study the preventions provided in section 2.
Disconnect a wire from the negative plug of the rechargeable battery (if it was not executed earlier).
If the radiator is removed for the purpose of elimination of a leak of cooling liquid, then keep in mind that small leaks can be eliminated without removal of a radiator from the car by means of sealant, for example the Holts Radweld type.
Merge cooling liquid from a radiator.
For simplification of access remove the soaking-up branch pipe of the air filter, disconnect a high-voltage wire from the coil of ignition and take him aside.
Disconnect contact sockets from a thermoswitch and the electric motor of the fan of a radiator.

Disconnect from a radiator hoses of supply of cooling liquid and a hose from a broad tank (fig. 5.3).
Turn off bolts of fastening of a radiator and bolts of fastening of collars, then lift a radiator up. On models with the automatic transmission the radiator needs to be lifted so that to provide access to pipelines of cooling liquid, to disconnect them and to close caps. Get a radiator from a motor compartment.
Carefully examine it, check visually for lack of a leak and damages. In need of repair it is recommended to hand over a radiator in a specialized workshop.
Remove with a brush from radiator edges the remains of insects and leaves, check and if necessary replace all worn-out hoses and collars.
The radiator should be washed out as it is described in section 2.
Replace a stopper of a radiator new with just the same data. If the stopper is replaced recently, then hand over it on check in service of car service.
At installation of a new radiator use all connections from the old unit.
Installation is carried out to the sequences, the return to removal, taking into account the following.
Be convinced of the correct landing of a radiator in places of fastening.
After installation of a radiator fill in antifreeze of the corresponding concentration in the cooling system, then launch the engine and check for lack of a leak.
On models with the automatic transmission check the level of working liquid and if necessary restore it.
