Why am I losing coolant from my van at such an alarming rate? on 1997 Dodge Ram Van 2500

Could it be that the water pump needs to be replaced? When the van is parked and shut off it completely drains the radiator,after sitting a period of time.

you need to fill it up water 4 now and put a piece of cardboard underneath it large enough to catch drips/pour from radiator to trans then note where leak/s are and report back
without more info it's hard to say could be anything from hole in radiator to freeeze plug leak
how do you replace a water pump
my 1997 dodge ram conversion van was doing that had 2 put anti freeze every 2 days finally my husband tore it apart and had to replace a hose that was hard to get in a tight spot but he got it and NO MORE LEAKS ......
