Many issues with 95 millenia need help

i know it need the valve seats to be replaced, but according to the gauge the car is over heating but the motor doesnt seem to be warn. also when maintaining a constant speed theres heat but the second u slow down u loose heat and wont come back till u maintain speed for a little while. Motor doesnt make any noise atifreeze is fine. Kinda stumped. Any help.

Might check the thermostat. Not sure if thats it or where it is on these cars. Ill check on mine to see if i can locate it. But thats what my mustang was doing and I changed my thermostat and it was all good.

wheres it located on the 95?

Thnaks
