Fan
The service manual states the fans at the front should automatically switch on when the coolant temperature rises 101/102°C. The temperature should then fall and the fan switches off when the temperature drops below 98/96°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. There is a legacy blue housing, part #A111E6047S as in the S1, but it does nothing.
The S2 and S3 (Toyota engine) has a single black temperature sender, although different part numbers in the 1Z and 2Z engines.
