Accord Cooling System

I recently replaced my Radiator, Thermostat, Rad. Cap and cooling fan switch
in my 92 Accord. The fan used to never come on when I turned the car off.
Now when I turn it off, the fan will come one and run for a few minutes,
shut off for maybe a minute and back on again and do this maybe 4 or 5
times. I know that is normal for it to come on after shutting the car off
but should it be coming on this often and run that long? Also, Is there a
transmission filter in a 92 Accord? I want to at least change the fluid, is
that all I need to do to it? I know the dealer will flush the cooler too,
but I figure doing it myself once a year should be almost as good.

 

On a really hot day, when the air conditioning has been running, my
radiator fan will behave as you describe. I can often prevent the
fan running on by shutting off the AC a couple miles from home,
giving things a chance to cool down some. If you open the hood after
shutting down the engine the heat will vent out and you may not get
any fan run, or at least minimize it.

Or you can live with it.

This was happening a couple of weeks ago when it was in the 30's here in
Ohio. Does run more that it is warmer now 60-70's though.

 

Did you bleed the air out of the cooling system with the bleeder valve?

Yes, or at least till fluid came out. Assuming I got it all.

 

The condenser fan will come up for up to 15 minutes after a shutdown if the
oil temperature is above 226F.

Congratulations. Your engine was probably running too too cool before.

If the fluid has been neglected for along time, there is danger in flushing
or replacing it: You may loosen accumulated crud, which can clog the valve
body passages. You're kind of in a tough spot here if you don't know the
car's history.
