Absolutely. I would definitely replace this.
You can check this by making sure that when you remove the thermostat it is cold and then dropping the thermostat into a bowl of boiling hot water and see if it reacts..... if it doesn't then that's the problem! If it does then flush the coolant system through with some radiator flush and then flush through with clean water before renewing antifreeze and water.

Check coolant level Perhaps thermostat is not opening to allow coolant to flow
1993 roadmaster overheats and then cools down?
I would guess that the thermostat is not opening at the proper temperature. Once it does open proper circulation brings it down to the correct operating temperature. I think it should be replaced.
Why does the engine warning light come on in your vauxhall astra with a simultaneous increase in engine temperature followed by a steep drop?
It sounds like the thermostat is opening up late causing the engine to almost overheat before it opens. Replace the thermostat.

You might want to check and see if the electric coolin fan is working. Also it could be your thermostat not opening and closing when it should.

The primary cause of a thermostat malfunction is corrosion. It prevents the thermostat from opening and closing as it normally would.
How do you know if the thermostat is bad on your 1993 mercury cougar 3.8?
In my experience with my 93 cougar, you can tell that the thermostat is bad by one of two ways. First, it overheats. If it overheats the thermostat is in the closed position and it is not opening up to allow the cooler water to enter the engine. Second, if during the winter the temperature gauge will not move up and the heater is blowing cold air, then the thermostat is stuck in the open position and is not allowing the water in the block to warm up. In either scenario, you should probably replace it. They are really inexpensive and can be replaced with little to no trouble. You will, however, need to drain about a gallon or so of the antifreeze so that the fluid level is below the thermostat housing. When refilling the antifreeze make sure you remove the bolt on the top of the engine so that it will allow the air to escape. Hope this helps.

How does a car still overheats when all of the fluid is not lost or leaking?
one reason being is the thermostat is not the right opening temperature another being your cooling fan is not working correctly so when you are sitting at a red light it will start to overheat your best bet is to try and change the thermostat for a new one which is only $4 at advance auto and see if that will do anything and make sure you flush out the coolant and put new in
