Thermostat — removal, check, installation
Removing the thermostat Removing the thermostat (3S-FE, 4S-FE). 1 - thermostat, 2 - gasket, 3 - inlet pipe, 4 - coolant temperature sensor connector, 5 - nut (M3 = 9.3 Nm). Note: Do not remove the thermostat unless...

Radiator: cleaning and checking
Radiator cleaning Flush the radiator with a high pressure hose to remove dirt from its core. Note: if the water pressure at the outlet of the hose is higher than 30-35 bar, then it is necessary to keep the spray nozzle...

Electric fan of the cooling system
Note: Air-conditioned models are equipped with two electric fans (one is the electric fan of the radiator of the cooling system, the second is used to cool the air conditioner condenser). Vehicle check 1. Check the...
