It will be the heater core. If you can smell it inside the car and it's steaming up the windows the core will need to be replaced. Remove the heater core housing and check to make sure its leaking from the core itself. You might get lucky and have a leak from the hoses running to core instead. Hope that helped.

SOURCE: How can I tell how long my heater core has been bad in my 2004 impala?

You can tell by the build up of the white powdery dried engine coolant around the area of the leak on the core. That is the only way.

How to replace 2008 impala heater core


Most heater cores are located behind the dashboard. This can be a difficult job putting it back together. Be sure it really is the heater core. ie water on the floor boards,the smell of antifreeze inside the cabin.Steamed windows all indicate the heater core.

Windows fog up


Could be either a plugged vent tube in the heater box [ it's on the lower outside of the firewall ] letting the water puddle and then evaporate when heated, or a leaking heater core. If it's the heater core, you will smell coolant inside the car and may have a wet area on the passenger's side floor.

While driving my 95 explorer i noticed the heater wasnt getting hot its luke warm and when i turn on the defroster i start to smell anti freeze and all of the windows fog up


no heat is probably low coolant or bad thermostat,although you have fog and smell ! the heating and cooling systems are closed systems the only way the windows fog is the coolant is hot and steams inside the car due to some leak inside the heater core box. as well as the smell being present. Now it is possible that a little leak has occured where the coolant supply or return line connects to the heater core and is running into the car which is running onto the core and creating steam and smell. hopefully it is a easy clamp tighten fix for you.

Why my window is fogging whe i turn the heater ?? i recently bought my toyota carina 3 model 1994 but the window is fogging , what should i do?


Make sure the vent system is set to draw air from outside. If it is set to recirculate the same air that's inside the vehicle without drawing fresh air from outside, the resulting humidity that builds up inside the vehicle can fog the windows even when you run the defrost. You can also try opening the windows a bit to get some more air moving inside.
If it still fogs when the vents are set properly, you may have a leaky heater core. The heater core is a small radiator that is located under the dash that the heater system blows air through to heat the inside of your car and provide heat to defrost the windshield. The fog may be coming from the heater core leaking hot coolant steam that's being circulated through the defrost system. If this is so, you will need to replace the heater core.

My widows fog up heavy on the inside when the defrost heats up


This is usually a good indication of a small leak in the heater core. Does it also smell really sweet?

2001 jeep cherokee- had the heater core replaced in Feb. 2008, when you turn on heater barely any air, when you use defrost a snell and the windows fog up. When you turn off car sounds like ******* comes...


Sounds to me like the heater core is leaking again. If you're smelling antifreeze and the window fogs up then you're getting coolant into the heating system. Most likely cause is leaking hose to heater core or the heater core it's self.
