Place a pan under the van and disconnect the heater intake and outlet hoses. Quickly remove and plug the hoses and support them in an upright position. Drain the coolant from the heater core into the pan.
When draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

A short cut for removing a heater core on a Ford Taurus. ... 04 Jeep Grand Cherokee: how to remove dashboard and replace Heater Core / AC ...
Sep 8, 2014 - Uploaded by Buckwsr
I walk you through replacement of the front heater core on a 2000... I just finished replacing the fuel pump and sending unit on my2000 Olds ..
most heater cores are behind the dash board on the passenger side.Look inside your engine u will see two hoses running to the firewall on the passenger side.They r going to your heater core.Sometimes you have to remove the dashboard completely it all depends on the car.
You will probably need new heater hose...first check heater hoses that run from engine to the
heater core......Most hoses will tear at the end where they are connected to the core and at the engine...First mark where each hose goes then drain coolant from system and remove both hoses...Take old hose's to parts store and get new hose's and clamps...They should be dryrotted
by the year of vehicle....It is easy to bend or break new core so be very careful when installing new core....After removing old hose's from core under hood you will know the location of the core....
remove screws under passenger side dash to remove core from inside of dash...very simple very easy....It looks like a tiny radiator with an in and an out spout...dont forget to mark where hoses
connect before removal.......Be sure and refill with new coolant/clamps/hoses because of age of vehicle...Both heater hose's that connect to the core are connected at the firewall on the passenger side of the engine...The core fits into the firewall dash and is connected to an input and an output hose...THIS IS EASY FOR BEGINNERS BUT BE CAREFUL WITH NEW CORE NOT TO BEND !!
most likely heater core and to check if the water pump working..allow vehicle to warm up enough for thermostat to open and check for circulation in the fluid inside the radiator..if see it..water pump works.
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink ant that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
