This 2000 Honda Civic EX VTEC D16Z7 started running hot last week and coolant was missing. I got my hands on the car today and found coolant leaking from beneath both hoses on a tee fitting located on the passenger side of the intake. I removed the hoses and found that the fitting was corroded. The smaller nipple was just about gone and destroyed itself just by gently pulling the hose off. I've had this car for about two years, apparently the previous owner used tap water for coolant...

Anyway, what to do? First thought is to replace this tee fitting but it looks to be pressed in. And the Honda eStore diagram doesn't show a part number for it.

Anybody know where to find this? Plug the fittings where the hoses connected at both ends? Or do I need to find another intake? Ideas?

Please correct me if I'm wrong - It seems the larger hose is a bypass before the thermostat that delivers hot water to the intake and the smaller hose sends hot water to heat the IAC; neither are necessary it seems (especially since I live in the land of everlasting summer).
