I broke one of the ports on this part but not completly sure what it is. Is it the Air pump switch valve? If so, where is the best place to get a new one?

it is not the air pump swith valve it is the coolant switch valve for your heater core. when the motor is warm vacuum opens the valve allowing hot coolant to enter your heater core you can get them at any auto parts store i did the same thing to mine when i changed my tpi gaskets advance auto had it for i think around $20
Awesome! thank you for the fast reply!!!
