Default Thermostat

I have a 2001 coupe I recently had the water pump replaced and the coolant system flushed. I am now noticing that the temperature gage will climb up to 220 -230 at idle. Should I have had a new thermostat put in when the water pump was replaced? Prior to the water pump issue the temperature gage would read 200 - 210 degrees at idle.

Well on these engines the thermostat housing bolts onto the water pump itself, the original design had it as one integrated unit. I don't know any competent mechanic that would replace the pump and not the neck or thermostat or at least inform the customer that it's a mighty good idea.
Stock thermostat opens at 187° and fans are set to start at well over 200° and the high speed fan at something like 235°. I'd replace it if it was me and I did when I had my water pump replaced.

Before you start throwing parts at it, follow the procedure to burp the air out of the cooling system.

Yes, it’s critical. These things can be tricky to fill properly.
