Fig. 2.177. Cooling system radiator components



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
After a detachment of hoses of the automatic transmission oil cooler it is necessary to close opening traffic jams in hoses, unions of a radiator and branch pipes of the automatic transmission not to allow an effluence of automatic transmission oil and hit in foreign particles.

Turn off bolts of fastening of support of a radiator.
Remove a radiator together with the radiator electric fan.
Remove the electric fan from a radiator.

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.
