    One heater hose is ice cold the other is warm but not hot.

    examine the water pump to see if it's leaking there...there is a seep hole at the front that starts leaking just before it fails. also you need to check the frost plugs at the rear of the motor to see if it's leaking there. when you feel both heater hoses ... are they hot ?

The heater core is plugged... try flushing it in reverse... water into the side that is cold.... and see if that unplugs it... if not you will likely have to change the heater core

When I put the heat on in my car it blows warm air for a few seconds then goes to blowing out cold air.


The lack of heat in the car has little to do with the car's cooling system, other than the hot coolant is the heat source. 95% of all "no-heat" issues are related to heater controls and/or the heater core itself. Since you get some heat, and then it goes away, this indicates a probable vacuum leak in the heater controls. When you select heat, vacuum is directed to a vacuum motor. This motor operates a vacuum actuator that moves a linkage that moves a door inside the heater box to direct the interior air through the heater core. If this actuator has a leak, it will activate, then as the vacuum leaks off, deactivate. You probably need to have a part replaced in the heater actuator mechanism.

No heat in 2001 dodge stratus,changed Thermostat still blows cold air?


Check the coolant level. If its low you wont get any heat. If its full then I would suspect that the temp. selector on the climate control is faulty. Farley easy to replace. Your local you pull parts yard will have one for $20-$35.

Over heating, replaced thermostat, still over heats, i have a 2004 dodge stratus, 2.4L DHOC


After changing the thermostat, did you fill it with 50/50 antifreeze to water?

Is the radiator cap (not actually on the radiator) in good shape and seating properly?

If the answer is yes to all of the this, than I would try picking up some heavy duty flush from the local parts store and flush the system really well.

Hope this helps.

No interior heat in my 2000 daewoo nubira


3 possible issues here,

the first is that your thermostat is stuck open, when this happens the air will barely be warm, luke warm at best, replacing the thermostat will fix this problem

the second, is that you have low coolant levels, when your coolant levels are way low, your heater core doesn't get the proper amount of coolant (if any) and the system blows cold air instead of heated air.

The third and final possibility, is that your heater core has clogged up (usually happens when stop leak or some type of radiator sealant is used) when this happens you can feel warm air when accelerating (test this by gently reving the vehicle and holding the rpm's when it is in park and holding your hands over the defrost vent to check for heat.

If you can tell me what symptom your vehicle is having I can help with instruction on how to fix it thanks cnc_couple@live.com

Dodge 2002 Grand Caravan V6 3.3 engine overheating/no cabin heat.


Replace the bad radiator hose first.  Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator.  Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it.  Fourth- Check for leaks by looking for the colored dye.  If it's not the radiator hose, then could possibly be a pin hole in your radiator.  Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

My dodge caravan 2001 is giving heating troubles. Will blow some hot air and then after some time, starts blowing cold air.


Ya I would almost guarantee you that the radiator is shot.
You will need a new one.
Cost 800.00 to 1100.00 to get a mechanic to install.
You can buy one your self for about 300.00.
Do it yourself.
to test if that's the problem try this.
Fill the radiator all the way to the top with coolant
Run the van till its warm check hoses to feel for heat.
If its all hot and good..then id say you got awhile before you will need a radiator.
What will happen next is your van will start to over heat when you least expect it to.
Good luck
