Buy a repair manual or do a search on for instructions on removing the dashboard, or enough of it to get at the heater box. you are lucky in that it does not have passenger side airbag.
when you are in there, do yourself a real favor do both hoses and the heater core. it is 20 and it is not unusual for them to plug up or leak at 10 so you are on borrowed time. when you have reached that point you will know that you never want to do this again.

Water leaking between the motor and transmission On passenger side on a 01 Mercury Grand Marquis

Check your heater core hoses, clamps, and so forth. Could be a clogged heater core, damaged core, rotted lines, broken clamps, cracked hoses, or even a plastic flush-out added to the lines thats dried-up and cracked from the heat passing through the lines. A clogged heater core could cause a back pressure and heat buildup that could easily cause this as well. You might be able to find the leak from up top, or you might have to get under the vehicle with a worklight and keep on looking for the source. Good luck.

Location of heater hose on 1998 plymouth grand voyager se

The heater hoses run to the backside of the motor and connect to the heater core on more towards the drivers side of the firewall. If you have rear heat there will be two metal lines that run under the vehicle on the passenger side. Those lines will connect to two rubber hoses that are attached to the rear heater lines that make there way to the rear heater core and connect just in front of the passenger rear tire.

How do you replace the heater core in a 1984 GMC 3500 camper

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 !!

MY 2006 Explorer was not putting out any heat and the fan clutch would speed up and sound like a Hummer. I refilled the coolant resivoir, and the radiator. I noticed the coolant would just disappear but no...

You may be able to braze (2) 1/2 in. copper 90 degree water fittings back to back to install as a jumper. Install jumper well ahead of bad hoses. I have never seen a stopped up heater core. Replace any suspect hoses and temp control valves.

Replace heater core

    A heater core transfers heat from a 1994 Ford Ranger's engine to the passenger compartment by running hot radiator coolant through a serpentine of tubing. Air blows past the hot fins of the heater core and into the truck cab.

    The hoses running to and from the heater core must be removed from the engine compartment, but the core itself is accessed from inside the passenger compartment, on the driver's side next to the center console.

    1. Turn off the engine, open the hood and remove the battery cable from the negative terminal. Make sure the engine is cool.

    2. Attach a 3/8-inch interior diameter hose to the drain outlet on the bottom rear corner of the radiator on the driver's side, and place the bottom end in a resealable plastic container. Turn the drain valve (located above the drain outlet) counterclockwise with a pair of pliers. Drain the engine coolant into the resealable container, then close the valve by turning it clockwise. Remove the hose from the outlet.

    3. Loosen the hose clamps on the radiator hoses where they attach to the heater core on the firewall. Remove the hoses.

    4. Unscrew the screws holding the underdash cover in place on the driver's side of the passenger compartment. Remove the underdash cover.

    5. Unscrew the four screws on the cylindrical heater core access cover and remove it. Remove the heater core by pulling it down and toward the rear of the vehicle. Replace the unit with a new heater core.

    6. Reinstall the heater core access cover and screw in the retaining screws. Replace the underdash cover and screw it into place.

    7. Replace the radiator hoses on the heater core in the engine compartment. Tighten the hose clamps. Add coolant until the level is between the minimum and maximum marks on the reservoir.

    8. Replace the battery cable and start the engine. Check the system for leaks.

Truck ran hot and when it cooled down put antifreeze in it notice it was running out from the bottom some where. Think I seen some type of steam coming up from the right passenger side,of what I'm not...

Well if the leak was starting from inside the car and dripping out the floor pan area, it is most definately a leaking heater core which is nothing more then a small radiator, however it is buried under the r/s dash behind the glove box and requires a bit of experience to R&R it properly, to be certain the core is at fault check the carpet on the pass side and see if it is wet under the dash area, if so it is the core if not you may have a rotted heater core hose or hoses, they(two of them) are the rubber hoses that sort of go from the pass. side of the engine through the passenger side firewall to meet up with the heater core supply nipples, they are both clamped on each end for secure fit, be sure before you do any work on the system that you let it sit and cool down as to avoid getting scolded by hot water/anti freeze, the two heater core hoses are distictly two different sizes one is 3/4" in diameter and the other is 5/8", both available at any parts store, dont forget to top off the anti freeze that leaked out using a 50/50 water to coolant mix.
After the repair is made and system is topped the vehicle for about 1/2 hour and recheck for any possible further leaks, fix and repair as needed.

My van is over heating there is coolant and water in the radiator it started leaking underneath towards where the front passenger seat

The problem sounds like either the inlet or outlet hose to the heater core is cracked or split. Or the heater core itself is at fault. Need to inspect the hoses from engine to the firewall going to the heater core for damage. If no leak from the outside then problem will be on the inside under the dash. Hope this will help you.

My 89 chevy caprice with a 305 is leaking antifreeze from the back of my firewall (passenger side) onto the exhaust pipe. It is dripping onto the exhaust just past where the two exhaust pipes come together...

Check the heater control valve and the hoses where they go into the firewall. If the leak is not there, then the most likely problem is a leaking heater core. You need to look carefully to find the source of the leak before you can repair it. Use a flashlight, mirror or whatever is necessary to do that. If it is a hose, use extreme care removing it from the heater core connection. best to cut it off with a razor blade. If it is the heater core,most times it will make the passenger side rug wet. If it is the core, it isn't an easy job and I'd consider either getting a haynes or chilton manual to guide you, or, have a good shop do the work.
good luck

99 jeep cherokee problem w/ heat I replaced the blower motor, water pump,radiator, thermostat and flushed the coolent system. Still getting little heat. I'm thinking heater core or head gasket... Is there...

It sounds like the heater coil needs flushing out or replacing or the heater valve. Look on the engine firewall and make sure the heater valve is opening. If not open it manually and check the heat level. If that produced heat check the condition of the heater vale cable (or vaccum hose).
