Good morning!

Recently I replaced my heater control valve on my Honda, it was spewing coolant so badly it was making my car overheat. The last day it was overheating like that it was pouring out steam under the hood. I managed to fix it with little trouble, first time Ive ever replaced anything under the hood like that (yay me)

Since replacing the valve it hasnt had any issues with overheating, no leaks no nothing. Until i started using my AC a few days ago. The thermostat crept up slightly, maybe a half inch total in movement. I popped the hood after i cut the car off and noticed the coolant flowing back into the reservoir, it actually overflowed it slightly. Yesterday i rode home about 3 miles with the heater on and the thermostat didnt move. But this morning i turn the ac on about a minute before i pulled into work and the temp jumped immediately.

Just not sure whats going on. Radiator fans kick on when the AC is on, no visible leaks since replacing the valve, AC blows cold heater blows warm. Curious if its the thermostat itself?? It sort of wiggles while the Ac is running but hasnt gotten dangerously hot at least.

Any comments are appreciated!
