The heater uses the coolant (read antifreeze and water) from the engine to get hot. If it runs low enough, by say leaking out of the heater core, your engine will overheat and that can be bad for it and expensive to fix.
Although most antifreeze is poisonous, (don't drink it) if you keep your window open the fumes will not hurt you. That being said, it will stain the carpet, make the inside of the car smelly, leave a puddle on the floor, cause the floor boards to rust(slowly) and mainly be annoying.
Since we are starting into summer you can get by for awhile by just adding water to the coolant tank under the hood. Make sure you do this when the engine is not hot. Engine coolant can give you severe burns if you take the cap off when the engine is hot.
So, about an hour after you get home from work go and check the engine coolant level. If you can hold onto the radiator hose then it is cool enough to add some more water. If you add more water then leaks out you can drive the jeep.
FYI The leak will get worse over time.

    Look if this person is dumb enough to ask if he/she can get by with it leaking inside the car, then lets not tell him/her to go under the hood and disconnect the hoses from the heater core and stick a 1/2in pvc nipple and 2 hose clamps. Now save up your money and get that core replaced.

    Didn't mean to be so brash with my answer but I didn't think anyone would want to smell anti-freeze inside the car. It gets on the windows, the upholstery and the clothes. In the summer this is a cheap quick fix untill you can afford to get core fixed which is involved and expensive. Just a word to the wise.

Check your coolant level. The heater pipe feeding your heater matrix could have sprung a leak. Your engine is at risk of over heating if your coolant levsl drops.

SOURCE: Brief antifreeze smell in Jeep

Make sure the cooling system is clean with fresh coolant when u change the core, otherwise u may damge the new core becuase your coolant is worn out, if your Jeep has over 60,000 it should be done anyway, also I recommend at least a new upper radiator hose while it is drainned and inspect the other parts of the system.

you could also be developing a heater core leak. if you start seeing fluid on the carpet or windows fog on the inside when defrosters are on, you got trouble. better to fix the problem now then in the middle of winter.

Signs of a bad water pump? loosing coolant.


Losing coolant can be attributed to a few things. Can be a leaking water pump. Does the area below the water pump look damp? May be a seal failure. Could be a leaking hose. Do you have any wet spots under the car after you are parked? May be a leaking heater core. In the passanger side footwell carpet damp? Do you smell a sweet odor? Or could be a head or manifold gasket. Check your oil. Is it cloudy or do you see water drops on the dipstick? Is the engine running rough? Do you have an excess amount of "steam" coming from your tail pipe? Those are the first areas to look. Let me know and we can continue to diagnose from there.

When i turn on the heat, I smell antifreeze right away then it goes away


Your heater core is leaking. The heater core on your 2001 Jeep Cherokee is responsible for providing heat in the cab of your Jeep. Overtime, he heater core can become plugged with dust or corrosion and stop working causing it to leak. The heater core is linked with the antifreeze that runs in the radiator in turn draws heat from the engine and than uses that heat to warm up the car. Most heater cores are located under the dash on the passenger side. Here is a link for how locate and remove the heater core. http://www.ehow.com/how_5332477_remove-jeep-cherokee-heater-core.html

Good luck! :)

Water is dripping from outer heater unit and soaking passanger side of front carpet.


There are two causes of fluid dripping from the heater core/ac evaporator housing. First, if it is running inside the vehicle and getting the carpet wet as described then it is most likely a bad heater core leaking antifreeze into the cab. Secondly, if it is dripping outside only when the a/c or defroster is running then it is the normal expulsion of condensation and is harmless.

Heater immediately fogs all windows and there is a sweet odor in the cab of 2003 Buick Rendezvous, defroster works fine, but will not clear the windows after heat is put on


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 !

That's not good! Are you finding puddles under the vehicle, or is your passenger side carpet wet? Is there any odor to the air. If any of this is yes, your heater core may be going out.

Wet floor passanger side


Air conditioning drain stopped up with debris (leaves,pine straw,sticks). Small tube sticking out from firewall with rubber elbow pointing down behind engine, passenger side. If elbow missing air will cause water to back up into vehicle. Another possibility, if your coolant is low heater core leaking.
