The only "sensor" for the mechanical fan is the bi-metallic spring which sets the tension on the clutch depending on it's sensed temp.
After reading more of your posts, I'm concerned that you have a different problem in the cooling system that just replacing the mech fan clutch isn't going to solve.
having the water pump fan running 'hot' will pull in more air than intended.....which should 'help' your other overheat symptoms. Kseal? sounds like something that clogs the radiator passages......
Well so far I’ve gone with the suggestion of ordering new fan clutch for starters. I don’t think there’s anything else going wrong with the cooling system because it’s been working fine all along (with the exception of the 1 condenser fan not working) but my a/c still blows cold and the gauge didn’t start going up unless it’s daytime, 95 degrees and traffic stop and go. So far it has only did it 1 time.
The reason I did k seal back in December, in cold weather I was having issues with coolant being burned on startup, and even a temperature gauge going up even though it was 3 degrees outside. Head gasket issue was suspected. K seal has good reviews, so I poured it in and the problem was solved.
Something causes my engine to misfire and knock when it’s much below freezing, while starting up from sitting overnight..the colder it is, the worst it gets. Fuel fumes spill into the cabin, and the engine usually stalls after running at only 500 RPM for a few seconds. The underside of the exhaust had even started smoking one morning while I was trying to warm it up.
I know that’s off topic, but it’s just one of the mystery annoyances that I haven’t bothered to diagnose...especially considering it never does it in warm weather.
Since then, I removed and flushed radiator while doing a/c condenser, and changed 2 radiator caps...
