Had to remove thermostat cuz car waz
running tagged when in approaching
overheated solved that by removing
thermostat. Used cardboard to block air
and that gave me heat. 1993 Subaru
stickshift. Here’s the problem
Why are the fans coming on in
cold weather when the engine temp
is not approaching warm? What type
of sensor would turn them on? I need
to shut them off cuz I don’t like them
pushing against the cardboard block.
Don’t want to burn out the fans!
Look forward to your answer !
thanks

Apparently your old thermostat was stuck closed causing overheating. I don't understand why you removed rather than replaced the thermostat. The engine will warm up faster and provide heat sooner with a correctly functioning thermostat. They only cost about $25 and should be replaced every so often anyway. So ????
If you want to shut off the fans and keep running without a thermostat you can just disconnect the plug attached to each fan. Keep a close eye on the temp gauge if u do.
The coolant temperature sensor might be faulty.
As a general rule it is not advisable to run without a thermostat especially in winter. The rings won't seat and everything else that has to stabilize at a fixed temperature will be unstable. Your car is almost 30 years old. You run the risk of burning excessive oil and or doing damage. Thermostats are cheap and since you already removed one you know how to install a new one. The fans may be on there own control which could include temperature and time. Blocking the radiators to get heat is very risky. What happens if your are driving and you don't notice the temperature creeping up. You don't have an protection that you would have with the thermostat installed.

that doesn't burn out fans. That's not how fans work.
You should probably repair your car instead of monkeying with it.

Nobody is removing Zs. That's just the way the rest of the world spells.
But I find your protest amusing 😆
Actually had a mechanic replace the
thermostat but had to suggest to him
how it could be done. In a Subaru you
need part of the thermostat to remain
to seat it when putting back. So you
have to remove the flapper/spring
and then install giving U free flow.
The car waz running “ragged” unsmooth
and shaky under acceleration, and
the temperature gauge waz barely
Halfway up it’s range. No Normally
associated Smell from overheating
waz detected, only poor engine
performance, which wazent observed
at lower temperatures. So minusing
the thermostat fixed that problem 100%,
during the summer. The Winter haz
been the problem and the temp gauge
clearly showz that, being slightly below
the line. One fan haz itz own fuze which
i will remove for the winter. Now from
your advice I shall rig up an on and
off switch for the second fan so when
spring arrives I can move to have 1
fan working when needed.
Now for the why I wanted to remove
the tStat. When visiting CT from NV,
i believe someone did something to
my car. I had the tStat removed so
i could get home. Just before that the AC
belt snapped cuz the AC pump froze.
Went from 18 mpg to 32 mpg. So
don’t want AC. I gave a lot of thought
about what could have been causing
the car to run ragged when getting
warmed but nowhere near hot ?
The only thing I could think of waz
shredded paper inside the coolant
system but that sounds a little
wacky ?
