After purchasing the car I noticed that neither of the two radiator cooling fan motors were turning on when the car warmed up and the motor would begin to overheat when the car wasn't moving. After further investigation I discovered that the RH (passenger side) radiator fan motor was seized. Even though the LH (Driver side) fan motor was in good condition, it did not turn on when the motor got hot so I replaced both fan relays (low fan & high fan) along with the RH fan motor and engine coolant thermostat.
Now, both fan motors turn on at high speed moments after I start the car and stay on anytime the motor is running. Needless to say, the motor does not overheat, and the needle always stays in the center of the operating range. Also, when I put the original fan relays back in, both fans worked the same way as with the new relays, so apparently the relays were not blown.
So I went from a situation where the radiator fans would not turn on, to one where they won't shut off (though preferable).
What else should I be looking at?
I replaced the engine coolant sensor as you suggested, but the "always on" issue is still present.
What else?
