Fan
The service manual states the fans at the front should automatically switch on when the coolant temperature rises above XX deg C. The temperature should then fall with the fans being switched off at YY deg C.
Temperature senders
The S1 has two temperature senders: brown (sends to ECU), blue (sends to dash). The blue temperature sender is notoriously unreliable and often fails, resulting in temperature readings approx 10°C lower than reality. The blue sender is also a "single wire" type which is affected by electrical load. In most cases, a 1°C rise in temperature can be seen when turning on each item of electrical equipment, e.g. headlights, heater fan, windscreen wipers.
The S2 (Rover engine) has a single (black) temperature sender for both ECU and dash.
The S2 (Toyota engine) has ???
