If you have a leak in the heater core, I would think that your coolant level would be going down. Also, you would smell the coolant-antifreeze inside the car. It might even be on your carpet. When your windshield fogs over, you would find it more difficult to clean the fog off the windshield. If you look under the hood, you will see two hoses attached to the firewall. Those hoses are the inlet and outlet to the heater core which is actually inside the car underneath the dash, and inside the heat ducts. It is not an easy job and actually some of the nuts holding everything may actually be on the engine side of the firewall..
 
I have a 1999 Taurus which has never had the well known cowl leak and which still has the original heater core. I have a 2007 Taurus which just had the passenger side leak and is just disgusting to me that Ford used the same old parts or else they used up old parts because they discontinued the old model Taurus. They do not give you any documentation on the leak repair under warranty probably to protect themselves.

HHHHmmmmm seems to me that I've got some issues to come looking at this forum but although my problem is a water leak form the heater core I do not have any water in the pax footwell (yet!). My leak is from a plastic oblong protrusion stcking out of the firewall toward the engine and I am getting the obligatory coolant smell inside the vehicle but I don't seem to be loosing water although the coolant is a brown muddy color. Anybody got any ideas on what this plastic part is and is this anything to worry about.

DISREGARD THIS MESSAGE. i SOLVED THE PROBLEM.
 
Symptoms as follows:
Car dies not have climate control.
Engine thermostat is functioning properly.
Coolant level good.
After engine is fully warmed up, turning on the heater only yields about 15 seconds of proper function with hot air blowing strong. After that, the air flow slightly decreases and the air blows cold.
Analysis:
Blend actuator door is closing due to a faulty signal from the temperature controller or the blend actuator door is broken.
Please advise or comment.
 
Thanks to all in advance,
 
Jakec

I just bought a 93 Mercury Sable 3.8L sedan. My concern is the average running temperature. When running on a cool day the temp guage needle sits in the center ( 1/2 up between the "R" and the "M" on the "normal" label) but on warmer days when running the a/c the temp guage looks a little high... about 3/4 of the way up (right below the "N" on the "normal" label). I know these cars tend to run a lil hot, but is this too hot and a reason for concern?

The engine will heat when hot ambient and running a/c. The cooling system electric fan should kick in when significantly above normal running temp. You can watch the coolant temp drop significantly when it runs or pull over, open the hood and see if the electric fan is running. The 3.8 is subject to head gasket failures. Neighbors 95 Sable with less than 30k had one recently. Get a coolant system service.

#63 of 94 2000 Mercury Sable heating and coolant problem. by sableowner

To begin with, I bought my Sable over the summer, used, from a private person (as opposed to a dealer). The air conditioner worked perfectly, and since it was summer I stupidly never checked to see if I had heat. Well, I didn't have heat when the cold weather came about. I took the car into a mechanic who scared the hell out of me with insane prices but told me nothing. He charged me $73 and didn't even have a diagnosis for me. He kept telling me that I needed to come up with $3000 just to find out what the problem was. Anyways, I took the car home, put blankets in the car, and started checking with friends to see if anyone could help me with the heating problem for the cost of parts and a home cooked meal.
 
Well, a friend was due to look at my car on Sunday. On Friday night, my husband and I are driving home when suddenly the car just stalls while being driven with tons of steam coming out from under the hood. The temperature gauge on the dash was in the green and in the middle between hot and cold. The car would not restart. We wait at the side of the road for it to cool just enough to limp the car into the parking lot that had a street light in it (we didn't have a flashlight). This parking lot was less than 100 feet from where it stalled.
 
Well, we couldn't help but notice that all of the car's coolant was on the ground underneath the car. We purchased more coolant, poured it in, turned on the car so that the coolant could circulate, but the car immediately dumped all the coolant on the ground. The car has enough oil, so there isn't a problem there.
 
One, what could possibly cause this problem?
 
Two, would the engine be damaged since, obviously, the engine temperature gauge isn't working and I don't know how long it was overheating before it stalled? (it was very late at night and to be honest, I was just barely staying awake at the wheel)

It sounds like a bad heater core, probably rusted. When coolant leaks out from underneath the car usually at the firewall is is the heater core. Check to see if you have coolant inside on the floor near the fan outlets..........hope it helps.........

Heater core doesnt leak but heat is weak. I bought a heater core which looks so substantial I cant believe the old one is clogged.
   Any suggestions before I start tearing apart the dash. thanks
