Hello, yesterday my car over heated, or so i thought i looked under the car and it was leaking anti-freeze all over the ground..i started the car and smoke was poring through the vents. So i immediatly shut off the car and was forced to get it towed home. My question is, does it sound more like just a break in the anit-freeze cables or would the damage be more extensive than that and be an issue with heating core. Also if so, i don't know much about cars and the heating core and dont really know how it works i know the antifreeze passes through there, but this would mean a whole replacement of the part, correct? I was also wondering, my car is a 92 Volkswagon GTI it would be nice for an estimated price of the parts, of possible and if i could get some more information on this issue.

If the water is clear no problem if it looks like anti-freeze your heater core is leaking the over heating could be from the lack of coolant from the leak but make sure to look closely at the intake manifold at either end as well
a heater uses the temperature of the cars water, running threw a heat exchanger if the heater core has failed water will not circulate threw the engine properly this will and can cause over heating as well as nothing blowing from the heater. good luck.heater cores are generally inexpensive parts to replace.
last thing you can check if heater core is ok. is the thermostat.
Sounds like a possible heater core failure(hole in it) the smell indicates to me the coolant(anti-freeze) is leaking into the passenger compartment. Check the carpet in front of the front passenger seat for moisture, this would confirm heater core leak. Good luck !
If you are getting steam on the inner windshield or it smell like anti freeze inside the veh, Yes this is a bad heater core...Check down under the dash pull back the carpet and if its wet, than also bad heater core..
I hope this helps..
Your car has a vacuum operated valve that directs the air flow from the bottom to the top, and it is most likely either that, or the heating control panel. Your bigger issue is the anti freeze smell. That is pretty much telling you that your heater core is leaking inside the car. The heater core doesnt cost too much, $25- $50 or so, but the fun part is getting to it. I have had to remove the entire dash from 3 cars to change the heater core, and one vehicle, my Ford Truck, was very easy, just removed the glove box to get at it.
Fix your anti freeze leak first, and inspect the heat valve and controls while the car is disassembled.

Is the leaking liquid antifreeze or clear water? Anti freeze is slimy. Ck your AC drain . its under the blower housinfg under the hood on the fire wall. The drain is easier to seeb from below looking yp. Squeeze it open and make sure it's clear. Good luck -Ned_
Sound like the tube that connects your heater core to the water supply from radiator. On Fords these tube are metal and very oftern rust out and need to be replaced. This is located behind and to the right (passenger) side of the engine.
You may have a leak in the heater core or the hoses to the heater core located under the dash. check to see if there is any moisture under your dash in the carpeting.fix the leak, and you will fix the cause of antifreeze on the windshield.
