1993 S 10 i have a leak i replaced the water pump and it started to leak again where else could it be leaking

Gasket may have slipped or defective pump. Is coolant coming out the vent hole? That's indicative of a defect. Otherwise see if you can see where coolant is coming from - use a dental type mirror if needed,

Thanks is there anything behind the water pump that might be leaking

dlesterjr; What engine? By pass hose, timing cover, t-stat housing or intake gasket leaking? Sometimes, a leak can come from above, run downwards, and 'appear' to be coming from the pump. Best thing, would be to pressurize the system, then check as Tom suggested.
