Overheating dodge caravan

I have a 06 Dodge Caravan that starts to overheat when the AC is on. when i turn it off and put the heater on it returns to normal. It does not always do this but over the past month it has happened about 4 times. What could be causing this?

Have pressure test done on the cooling system and check for partial blockage in the radiator cores.

The only thing i could figure it was after checking the "easy" things was the head gasket. tore it down this morning and sure enough that was the problem. now that i have it a part i am going to do a complete rebuild on it, then it will last me for a while longer and i won't have to worry to much about it.
thanks
jen

Did you bleed the cooling system after refilling the radiator ? to bleed the system, fill the radiator with water and coolant. Run the engine until it is at a good temperature. Then turn off the engine and look for a bleeding screw at the oulet of the thermostat housing and turn it with a screwdriver counterclock wise. The trapped air will go out and coolant will start coming out. refill the radiator and repeat until only coolant comes out and no air.be careful not to burn yourself.

air pockets in the cooling system can cause this problem. idle engine with radiator cap removed for 10 -15 min. Do not let engine overheat and make sure coolant lvl is topped off. this should bleed all air from system.

Where is it leaking from? The radiator its self, the heater core found under the dash, or some where in between? Look for pools of coolant under the front floor mats, If you find it there, then the heater core needs to be replaced. Next time it happens, Pull over immediately and look under the car to see where it is leaking, (look from more than one angle). Or park it over some clean cardboard, where ever the stains are, will give you a clue of where to look for the problem. And most easy, Bring it back to the mechanic who installed the new radiator., Most legitimate mechanics warrant their work and yours may be responsible in some way, or at least be familiar with your particular Caravan.
The solution is to locate and fix the leak, but also perform a thouro cooling system flush. The system bay have serious dirt, clay, or corrosion that is causing issues with proper flow and pressure, thus causing leaks.
And Always Pull Over when it begins to OverHeat! Heat damage to an engine can spell Death to any Car, even Caravans. Good Luck.

98 dodge caravan overheating...heater works..checked fans they came on later but when I drove it after it cooled down and it overheated...check engine lite came on.


About the only things are the thermostat and the water pump.There could be something with the radiator but that is the rarest because the water shoots straight through.If it overheats fairly rapid,it's most likely the thermostat.Sometimes a water pump will let you go 20-30 miles before overheat.The thermostat is cheaper and easier if you're going to try it systematically.Overheat will probably cause the check engine light too.Good luck!

2001 Dodge Caravan heater blows cold air when stopped


Have you checked the coolant level? What you describe is exactly what happens if the coolant level is low. When stopped at idle, hot coolant is not circulating through the heater core, so no heat. As the engine increases in rpm's when you pull away from the light, the water pump is spinning quicker, and some coolant is making it to the heater core. So check the level, and if it is low, keep an eye on it to see if it drops again. That of course indicates a leak somewhere. Get it fixed, as overheating the engine leads to costly repairs and worse case a new engine. Let me know how you make out with this.

I have 97 dodge caravan 3.0 and i put in a brand new radiator and thermostat.Now the cooling fans dont come on and fluid is bubbling up and coming out of the reservoir. But if I unplug the temp. sensor...


Not unusual to get big airlock if heater (not defrost) isn't on during bleeding process. I usually start vehicle, top up rad 1 " or so from top,turn heater on , then watch temperature gauge & wait for fan to come on after I see flow through rad indicating thermostat opened.(Normal operating temperature)I let it do that about 3 times before I put rad cap back on, after topping rad up to about an inch or 2 from top. Then fill coolant return bottle, to proper level. It may be your problem, but if your temperature gauge goes way up past normal operating temperature, before you see flow in rad, then maybe a faulty thermostat is the cause.

Caravan overheating- what should I check out next?


does the fan come on when the ac is on? if so the fan is most likely ok, the problem on this car is most likely the cylinder head gasket is leaking.

there is two solutions possible:

1. the wire you put in is way to small so it will overheat

2. you have a bad connection or ground somewhere that allows overheating...

either way it's gonna catch fire sooner or later...
