Pressurisation | Cap with 1,4 bar rating |
Opening of thermostatic regulator | 83 °C |
Fans 1st speed triggering threshold | 96 °C |
Fans 2nd speed triggering threshold | 105 °C |
Warning | 118 °C |
Post-cooling | 105 °C (For 6 minutes ) |
Number x electrical power | 2 x 150 Watts |
- Temperature increase phase (Cold circuit )
- Temperature regulation phase (Hot circuit )
Above 83°C the thermostat starts to open, the cooling circuit enlarges, the coolant fluid is cooled by the radiator, thus regulating the engine temperature.
The engine management ECU controls the fans via a relay allowing the fans to rotate at two different speeds according to the temperature of the engine.
- The engine management ECU activates the slow speed of the fans when the engine coolant temperature reaches 96 °C.
- The engine management ECU activates the fast speed of the fans when the engine coolant temperature reaches 105 °C.
Just one other thing - consider that the fault may also be with the blown air temperature sensor, which is another component associated with lack of warm air....
