I've got a 1995 K1500 Z71 with 276,xxx miles and I'm leaking coolant underneath towards the passengers side. Its started doing this ever since I replaced my waterpump and busted radiator. It only does it while my truck is running and is stationary (as far as I know). Im guessing ever since i changed the radiator and water pump the system now can hold pressure and its found a new place to leak out and I'm just not sure exactly what the issue is. All help is appreciated!
