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

Replace the thermostat and look for leaks if the coolant is low water pump or rear heater tubes(if equipped) are common leakers

I have cold air blowing from the heater on my 2001 Gand Caravan. It will sometimes start to blow warm to kind of hot when driving but at an idle the are is cool. There is a small leak on the passenger side...


seems like you are losing pressure in the system as the coolant gets hotter it builds up pressure if you have a small leak when it gets to a certain pressure it will blow out and you lose pressure and the heater will blow cold, run the motor till it gets hot and look for coolant or steam coming out, check the coolant cap while your at it

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.

After car heats up (slow to heat) it stil blows cold until moving


You have a circulation problem, heater core may have restriction that why heat only comes when you drive ,also you may have a thermostat that stuck in the open position. Good Luck
