If you smell antifreeze, there is a leak. it may be just coming from a hose connection to the heater core. Have them recheck the connections and inspect the cooling system for a leak. It should be evident when inspected. Also, what your engine temperature when operating the Jeep, If the coolant is low,from the leak,you can start to overheat.

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! :)

Either its the heater core or the thermostat


your heater core is definitley leaking and your blower is pushing the vapor into the cabin. It will only get worse. You can minimize the smell by not running your heater or defroster, but you wont prevent the coolant from leaking and potentially getting worse. Sorry to say, the core will need pulled and repaired or replaced. Sometimes stop leak additives will solve the problem if its not too severe. I have never been a fan of them, its only a band aid in my view. also if u got pets afoid leeting they smell the antifreeze very toxic can kill pets easily. hope this helps. rate above 4* cheers

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.

Smell anitfreeze when turning on the heat


A good indication that the heater core is bad, is if you get a oily film on the windshield when the defroster is on. If the headgasket is leaking, the engine should run hotter than normal,you might get oil in the radiator,you might see coolant dripping down the engine. I would start with checking out the heater core first. It is a very big job(the dash has to come out).

??? heater core


If you smell antifreeze, the problem would be the heater core.
Another indication is when you turn on the defroster and see a oily film on your windshield.
The heater core would have to be replaced.
In order to do this the whole dashboard would have to come out to get the heater box out.
In a dealer the process would take about 4 hours from qualified mechanics who have done this before.
