Question about 1999 Jeep Grand Cherokee

Brief antifreeze smell in Jeep

When I start my 2001 Jeep Grand Cherokee, there is a gurgling noise in heater core area and also slight antifreeze odor. All online forums point to a leaking heater core, but the passenger-side carpet is totally dry and also the odor goes away in about 30 seconds. After that, the gurgling remains but no more smell. Ideas?

    Your heater core is just starting to leak. the gurgling is most often causes by low coolant level, is the system clean and full?

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 are at the beginning stages of the heater core going out on you..just because theres no moisture inside doesent necessarily mean the heater core is still ok it just means its going to start leaking on the outside more than likely

The forums you have read are probably right.that's what it sounds like. You are just lucky that is hasn't started to leak really bad so far.

On a 2000 jeep grand cherokee what does it mean if the heater smokes, smells like antifreeze and window fogs up when heater is on?


It is not smoke though it appears so. It is thick heavy steam from a coolant leak in your heater core in the cabin area. It will smell very sweet if it is a typical glycol based antifreeze, and the windows will fog up as the hot coolant enters the cabin area of the vehicle. Primarily on the inside of the windshield. The cure is that your going to have to replace the heater core as it is leaking. Do this soon because if it ruptures completely you will have a major mess on the floorboard of your vehicle. Coolant is also poisonous to humans and animals if ingested. The heater core will be a little pricey as will the labor to replace it. Good luck. I guarantee you it is the heater core leaking.

I have a 1997 grand cherokee and i got a new heating core put in but sometimes when the heater is on you can smell antifreeze.


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! :)

I have a 99 jeep grand cherokee with water flowing from a what looks like a drain from the heater core area. the floor isnt wet and the heater works could the heat core have a crack


Is water coming out or is it antifreeze? If its antifreeze you have a heater core leaking. If its water than it's normal. The air conditioner is also a dehumidifier, and that is where the condensation comes out.

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.
