As thermostate valve opens the water flow channel at a specific temperature, does the same Temperature threshold apply to thermostate switch as well? Like is the opening of valve and turning on off radiator fan synchronized?
Thermostate valve starts to open at around 78 °C and gets fully open at ~90 °C, while the thermostate switch closes between 92 - 95°C.
P.SThese figures are specific to honda engines but can be applied to other engines with slight variations.
