Do the cooling fans come on together or separately? Are the fans activated by thermo switch or temperature sensor? I noticed loss of coolant.I changed thermo switch, I did radiator flushing, new thermostat.

Do you think the temperature sensor faulty. Should fan 1 switch on when activated by thermo switch or the two fans come on together when coolant hot and thermo switch closed?

When ever engine reaches a certain temp or a/c on that least one of the fans should work. We don't have that model in u.S. So i'm looking at a camry model which is similar I believe. There are two switches one in front and rear of engine for this as well as 3 fuses, two under hood and one under dash. There are also three relays which all three are under hood. Any one of those could be bad. However if one fan is in front of a/c condenser it will only work when a/c is on. If you can find relay 1 that is the one that should run the cooling fan and the two fuses under hood.
