SOURCE: Where is the drain valve on 2002 dodge caravan radiator?

its a pitcock facing the cab bottom of the radiator, plastic flat. once you find the pitcock just put a bucket underneath and turn it.then refill. if you want to flush(run fluid thru to clean it out) the radiator id suggest taking it in. you dont have to flush it every time you change the coolant out.

SOURCE: Heater blower motor replacement -1997 Dodge Grand Caravan

Remove the cover plate on the passenger side of the heater box, 3-4 screws.
Unplug the motor assembly, remove 3-4 more screws that hold the motor in place and pull it down from its position. Get an aftermarket motor and installed it in the original housing with the original squirrel cage.
Installation is the reverse of removal.

SOURCE: 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.

1999 Dodge Grand Caravan heat is cold


There are two possibilities, one is the thermostat. Many people remove them which spoils the whole heating / cooling system. Since you changed the thermostat, I would check the heater valve on the heater which allows the hot water to circulate through the heating system.
It may be necessary to remove the heater box and flush the heater core since you talk about a lot of rust, which could have clogged the heater core and / or the pipes leading to the heater.

Dodge caravan heat fan won't work


If it is the fan/blower that is not working (as opposed to what is coming out is cold), then the problem could be 1) fuse 2) Blower Resistor. I just replaced the blower resistor in about 15 min with a $25 replacement resistor. The unit is right behind the glove box.

If the problem is that the air coming out is cold and not hot, then the thermostat, radiator, heater core, etc... are the more likley causes.

I have a problem of 2002 dodge caravan the heater is blowing cold and less coolant fuild in radiator but engine does not over heat


it sounds like you need a thermostat replaced, and fill the coolantup. start by topping the fluid off, run it for twenty minutes, if you get heat, the problem was low fluid, i not, replace the stat, and fill withthe proper coolant after you are done. good luck

The heater is blowing cold air


heater control valve not allowing radiator water to flow through the heater core where the heater blower motor blows the heat that radiates off the heater core into the vehicle cheap fix or you can bypass yourself by replacing valve with piece of 3/4 copper pipe and 2 hose clamps

Just had rad flushed still no heat in 99 caravan 


Take the car back in and have them disconnect the heater core hoses. Using an air compressor, blow into one with the other in a bucket to catch the coolant and any debris. Then swap hoses and blow it out the other way - that way if there is anything jamming the heater core, it'll be blown out into the catch can. You will need to add coolant and burp the radiator afterward (see the tips and tricks section on this site - I put in a description of how to burp the radiator).

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.

Heater blowing clod air


the heater core behind the dash may be bad, it is the coolant tank for the heater system that is to say it is where the heat comes from. kinda pricey to have repaired at a dealership, if you can hear the fan turning but no heat, than it is a good possibility, or a vent hose has fallen off, get down and check under the dash
