1993 SC2 temp gauge 1/4 to 3/4 and back

I have heard a lot of people have the same problem as me. It seems there is
not enough air getting to the raditor at first. Then I realized that the
temp gauge goes up to 3/4 at regular intervals then the fan kicks on and
drops it to 1/4 in a matter of minutes.

The process then repeats. I think this is unnecessary wear and tear on the
engine. Does anyone else have this problem? Is it normal? and Can it be
cured by replacing the temp. sensor?

My heat is fine and it's the dead of winter and the car still warms up in
a few minutes. I just don't want to subject the engine to constant heating
and cooling. I only have 97600 miles.

 

Once again, This is NORMAL.

 

That is normal if you are sitting in traffic. If you are moving over 10
mph, the gauge shouldn't go up unless you have a problem...

I wish there was a way to program the fan to come on at the ½ mark
instead of ¾ mark.

If you are in traffic, you can turn the AC on for about 5 secs and then
turn it off. The fan will run for about 4 minutes after you turn off
the AC causing the temp to stay down.
