What tweetie said, plus
If you have not checked or changed the radiator fan thermoswitch, do it at the same time as the thermostat.
Also be sure the fan relay is operating correctly and its connections are not corroded. If the relay fails, the fans may not operate or they will not stay on after the ignition is turned off. What the relay does is it keeps the fan(s) running for a little extra time after the thermoswitch closes and then opens. What happened on mine was the relay died and then only the thermoswitch operated the fans, so they would turn on and then cut out five seconds later.
If your car is 1991-93 nonturbo see the service bulletin about rewiring so both cooling fans come on simultaneously. This and the cooler-value thermoswitch are highly recommended.
