Please write the VIN number down - and take a screen shot of the part to your local dealer. They will have the part number and the part.
I know this sound expensive but in the long run you will be glad you did. While you're at the dealer ask about any recalls or Service bulletins. These two things will save you a lot of money over the time you own a vehicle.
I have taken a screen shot of the part but you might be better off taking the car to the dealer and simple ask them to look at it.

You should be able to go to the dealer and describe it - I would say its a bypass fitting for the heater hose. I doubt it is available from auto parts stores yet. Not enough demand.

Your leak could be a clogged a/c drain tube.
Does this happen with a/c on or defroster?

SOURCE: heater core blowing cold and leaking coolant

Locating the connections from the engine compartment to the heater core shouldn't require a diagram.
Check the hoses and their paths and you will find two that go through the firewall via a fixed connector; these are the in- and outlet for hot water circulation. Since the hoses have had a dozen years to weld themselves to the fitting, they probably won't be easy to remove; it may be necessary to **** them with a razor blade and pry the hose from the fitting.
If you have a little junk pipe pieces at home, either 1/2 or 3/4 should be a fit to couple these two ends together after they are removed from the connectors that you'll find at the firewall.

Probably still some left in the heater core. Should quit after a while, or try blowing it out. I would even flush it with water first. Better to have water leaking than antifreeze. At least your dog can lick it and not die!

The car has a coolant leak from back of engine on passenger side.

Sounds like the drain line from the heater/air conditioning box. There is a drip pan inside the heater box to catch condensation from the A/C coil. Normally, only water comes out of there, but, if the heater core springs a leak (and they do), then the tray catches the coolant and diverts it outside the car. You'll need to confirm the heater core is leaking and if so, replace the heater core. Not a fun job on many cars.....

I need to bypass my heater coil as my aircon is leaking 2003 kia pregio any photos?

Im not quite sure what bypassing heater coil has to do with aircon leak, unless you mean there's coolant leaking from under dash, if coolant is leaking, remove hoses at firewall and follow them back to engine, you can use one of them to bridge from one to the other. Or put a connector between the hoses

Antifreeze leaking out of a plastic tube under the heater blower

This is coolant coming out of the condensation pan inside the vehicle. It is a classic indication of a leaking heater core. Ensure that it IS coolant and not just water which is normal from there with the AC running. If it is coolant, you will need to replace the heater core. Keep close watch on your coolant levels to avoid overheating the engine. On most vehicles, you can temporarily bypass the heater core by removing the heater hoses from the firewall and connecting them together with an adapter you can get at most auto parts sores. This will allow you to use the vehicle until you can get the parts and arrange repair time. You will not have heat however....

I put coolant in radiator and I get a/c but my heat doesn't work. I think my heater hose was bypassed by the previous owner. How do I fix the problem?

You should be able to look down in between the motor and the firewall and see if the heater hoses are attached to the heater core. Most of the time when they are bypassed it is because the heater core has started to leak. Instead of replacing the heater core (not a fun or easy job) they just bypass it so they won't leak coolant. So, if it is bypassed your probably looking at replacing the heater core in order to get heat.

I have a 2001 Legacy twin turb Gtb Wagon, When im driving i can smell an oily smell coming through the Air conditioning. the Smell is actually quite similar to burning coolent. whats the guts with that?

Hi and welcome to FixYa, I am Kelly. You have a leaking heater coil. Check your radiator coolant levels and I am certain that over several days you will note your car is suddenly using water. That sweet oily smell is anti-freeze. Many people bypass the heater coil lines in the engine compartment until they can get the heater core replaced.

Bypassing the heater core is done by disconnecting the lines forward of the firewall in using a pipe nipple or piece of copper tubing with clamps. I recommend you either bypass the lines or have the heater core replaced ASAP. You run the risk of overheating your engine from coolant loss.
Thanks for choosing FixYa.

Floor board is wet on driver side front and rear

Check the weatherstripping around the door. Also look under the dash board for signs of water leaking from the firewall. If your weatherstripping isn't damaged anywhere then make sure the liquid doesn't smell like antifreeze. If it does then you've busted the heater coil. Do not drive the car if this is the case. Your coolant will all leak into the car and it will overheat. Replacing a heater coil tend to be a huge pain in the **** and if you can pay someone else to do it by all means do. The heater coil can be bypassed by connecting the water inlet hose to the outlet hose where they go into the firewall. This is a crutch but your car will run fine until you can get the heater coil replaced. A mechanic will do the bypass for you pretty cheaply. It only takes 5 minutes.

Need to replace heater raidator under dash.anyone done one

The heater "coil" almost always requires removal of the entire dashboard and it's not much fun. You shouldn't even think about it without at least a Chilton's (or other) manual unless you're pretty used to disassembling and reassembling complex components. If it's leaking antifreeze, you can bypass the heater for now (brrrr) by splicing the heater coil's inlet and outlet hoses together. In the engine compartment look for two hoses, same sized, that are leading into your firewall. They'll be right next to each other, usually one above, rather than beside the other. They'll be the only hoses with anti freeze that attach to the firewall. Pull both hoses from the firewall and insert a splice, connecting these hoses. Secure with hose clamps. This will seal the coolant system and bypass the heater. The car will be perfectly safe to drive now until you replace the heater coil.

I am needing advise on the heater core for my 95 grand am. it is leaking on the floor board passenger side pretty badly (front and back) . Is this something a stop leak would be worth trying until the...

Don't use stop leak, use regular kitchen black pepper. About 2 tea spoon should stop the leak soon as the pepper makes it way to where the leak is. Black pepper will clean up after you flush the coolant system and will not leave any residue like the stop leak that will restrict the coolant journals and water jackets in the engine block and radiator.

Removed the center console to get to the panel that holds the heater core. the heater core is in the center of the car under the radio. There are 7 screws holding the cover on. Once you remove the 7 screws, there are two straps that hold the core inthe heater box (2 screws per strap. Some cars are easier to get the heater hoses from underneath after jacking up the car, some you can get to from up top under the hood behind the engine. It's not a 15 minute job, but not difficult at all. I usually suggest pulling out the passenger side seat to give a comfy place to lay while doing it. the seat comes out with only four bolts, and you won't have to contort your self to get the heater core out. Your low coolant light is due to air trapped in the system. Anytime you open the cooling system on a 3.1, you have to bleed the air out using the bleed valves on the t-stat housing and transfer tube (some only have one on the t-stat housing. If you have a 5 speed, your going to remove the shifter knob and just yank on the plastic that had the boot. (it only has snaps that hold it on) Then there are 2 bolt holes in the armrest compartment. and 4 more which are under the boot and plastic. Very easy to take off and put on.

Good luck, and other way is to by pass the heater core at the heart hose, but your not going to have any heat.

Water leak on passenger floorboard also an ac problem

probably leaking heater core. you may have low coolant level now. the only place water comes in the cabin is for the heater, that has got to be it. the heater core can be bypassed (like my car's is) by simply cutting the hose that leads into the car and leave about a foot, make a big U out of it and plug the other side of the hose into the coolant passage that returns from the heater core and leads into the intake manifold. pretty easy you will need a knife, hose clamps, and common sense. the third one is a little harder to come by! :)

That drain line is for the box that holds the air conditioner evaporator and the heater coil. It seems that your heater coil has sprung a leak and the leaked fluid is coming out the drain. You have to replace the heater coil, which on most cars involves removing a lot of the interior equipment, including the dash board on many cars. A job best left for the repair shop unless you're very adventurous and patient. Even then you will have to take it to a shop to have the air conditioning system recharged.
