Works only with heat turned on.
When heat turned on, could see the two speeds (HI/LO) both working fine.

However, fan does not work without the heat (AC) switched on.
Neither Hi, nor low fan.

So, without car heating turned on, the heat gauge goes up near the red zone.

So, the coolant temperature is being regulated well and no heat ups.
Waited long to test this on a hot day.
My last test will be to see it with air conditioning turned on and a hot day. For now I'm good.
It did take the car days to gradually adjust to a new radiator and a new cooling fan assembly. And during this time there were times things notched up on heat.
Have a good one!!!
