I replaced the H2O pump in a 96 Dodge Ram 1500 b/c it was leaking. Now I have a leak near the passenger side. It might be the heater control valve b/c the heat doesn't work. How do I know for sure?

get a dye at your parts store and put it in the system and let it run. it will show the leaks very well.
