No, they are two seperate sensors.
hi, fans will work when power is jumped direct to fan wiring, . but not with relays or sensors, replaced relay number one but still not working as factory set up. is sensor on radiator a coolant level sensor or fan sensor to trigger relays
Your reservoir may be low. This will trigger the coolant light. It is often a malfunctioning sensor and nothing is actually wrong with the cooling system or coolant. It can be easily replaced. Alternatively you can leave it, but monitor your engine temperature and coolant level.
If by cooling system you mean the cooling fan, it takes a while for the coolant temperature to rise enough to trigger the temperature sensor that activates the fan. This is to help warm up the engine and to avoid unnecessary operation of the cooling fan when it is not needed.
Don't know for sure but check in the radiator overflow. Tip: The radiator can be full but if the overflow is low or empty it will trigger the light.
Perhaps the coolant temperature sensor isn't fucntioning properly, and not sending the proper temperature to trigger them. Sometimes the relay that controls them can go bad too. If you can, also try checking the ground points for the fan circuit.

A 12 volt trigger, typically found on high end audio visual receivers, is not designed to carry a full load. In order to run a cooling fan the 12 volt trigger should be used to trigger a switch (easily obtainable) which will then turn on the fan.
A humidastat works with a cooling unit or humidify. It measures the amount of humidity in the air. This can then trigger the unit to turn on or off removing excess humidity from the home.

The service engine soon light on an Oldsmobile Cutlass Supreme notifies the driver that it is time to change the oil. It is trigger around the 3,000 mile mark at regular intervals.
The second trigger is usually a "set" trigger, that spring loads the forward trigger and makes it into a hair draw trigger.
Rear trigger is "set" trigger, by pulling it 1st, it makes the main trigger a "hair" or lighter trigger
