Removal, check and installation of the radiator cooling system
| Fig. 2.177. The components of the cooling radiator
|
Withdrawal Disconnect the radiator fan motor connector.
Remove the radiator drain plug and drain the coolant. Remove the upper and lower radiator hoses and tube expansion tank. On models with automatic transmission oil cooler hoses, disconnect the automatic transmission.
ATTENTION After disconnecting the automatic transmission oil cooler hose must be closed with plugs holes in hoses, pipes and fittings radiator automatic transmission, to prevent leakage of oil automatic transmission and ingestion of foreign particles. |
Remove the bolts from the radiator support. Remove the heat sink together with electric radiator. Remove the fan from the radiator.
Check Check the radiator no bending or damaging the plates, and the absence of foreign material between the plates. Check the radiator for damage and scale deposits, rust or corrosion. Check the radiator hoses for cracks, damage or deterioration (wear). Check the expansion tank for damage. Check the spring radiator cap for damage. Check the valve opening pressure of the radiator cap with a special tester to check the cooling system.
The electric radiator fan
Verify that the fan heatsink is rotated when the motor is supplied to the findings of the battery voltage (Fig. 2.179). Check for unusual noises during the rotation of the radiator fan.
Setting Fill the radiator expansion tank and clean coolant. Start the engine and warm it up until the opening of the valve of the thermostat. Then stop the engine. Remove the radiator cap and add coolant to the base of the filler neck of the radiator, and then add a liquid in a broad tank to the top mark. Make sure there is no leakage of fluid from the radiator hose or connections.
