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.

How to change a heater core in a 93 jeep grand cherokee


When I turn my heater on, after my 1993 Jeep Grand Cherokee has warmed up, there is a dusty, watery smell for a few minutes, then it goes away. Also, it doesn't put out as much heat as I think it should. I don't think the heater core has a leak, because I always seem to have the same amount of coolant in the radiator and the heater core is not leaking on the inside of the truck.

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.

I have a 2001 Jeep Grand Cherokee. Originally blew only cold air no matter what the heat settings were at. Then blower stopped working. Discovered wires were corroded and replaced them as well installed...


either bad recirc doors or a possible bad heater core. Open the hood and when the car is warmed up to mid point on the temp gauge look on the passenger's side firewall under the hood. You will see 2 black rubber hoses running through the firewall. Feel each hose and if one of the 2 are cold then you have a bad heater core. Otherwise most likely the recirc door.

I have a Nov 1990 Cherokee jeep Laredo with a heating problem. The radiator and thermostat have been renewed with the problem still has'nt been licked. Any suggestions for what to do next? Dave


If it's lack of heat, it could be the heater control valve. If the jeep has alot of miles on it, the heater core should be reverse flushed.

I have a Grand Cherokee Jeep 1994 Estate. Heater problem


you may need to add coolant to the system, If it is full check to see if there is a valve on your heater hose running from the engine to the heater core. If there is, make sure the valve is in the open position when your heater is on and the engine is up to temp. If that doesnt help try flushing the sytem, you may have a plugged heater core.

1st, the fuse location is marked, what is the 20 Amp fuse for? 2nd, did the smoke have a nauseating sweet smell to it? If it smells like described it is the heater core leaking, coolant steam looks like smoke.
