Removal
Disconnect the radiator fan electric motor socket.
Fig. 2.178. Temperature regulator switch
|
Install temperature regulator switch in the provision of the maximum heating (fig. 2.178).
Turn off a drain stopper of a radiator and merge cooling liquid.
Disconnect the top and lower hoses of a radiator and a tube of a broad tank.
On models from the automatic transmission disconnect automatic transmission oil cooler hoses.
ATTENTION

Check
Check a radiator for lack of a bend or damage of plates, and for lack of foreign objects between plates.
Check a radiator for absence of damage and deposits of a scum, rust or traces of corrosion.
Check radiator hoses for lack of cracks, damages or deterioration in a state (wear).
Check a broad tank for absence of damage.
Check a radiator cover spring for absence of damage.
Check pressure of opening of valves of a cover of a radiator by means of a special tester for check of the cooling system.
Radiator fan electric motor
Fig. 2.179. Check of the electric fan of a radiator
|
Check that the electric fan of a radiator rotates when on conclusions of the electric motor tension of the rechargeable battery (fig. 2.179) moves.
Check lack of extraneous noises at rotation of the electric fan of a radiator.
Installation
Fill a radiator and a broad tank with pure cooling liquid.
Start the engine and warm up it until opening of the valve of the thermostat. Then kill the engine.
Uncover a radiator and add liquid to the basis of a bulk mouth of a radiator, then add liquid in a broad tank to the top tag.
Be convinced of lack of leak of liquid from a radiator, hoses or connections.
