More than likely your thermostat has frozen in the closed position. If you take the neck off of the engine where the main hose goes into the top of the motor, you should see the thermostat. Make sure when you are changing it that you have it facing the right direction and that you clean an properly seal the neck when re-installing it. Hope this helps!

SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

SOURCE: 2000 Dodge Ram Heat not hot, only luke warm @ idle

did you use pure antifreeze if so remove it all and add a 50/50 mixture because antifreeze will not heat up good if its pure. needs water to allow good heat.

SOURCE: replaced thermostat and flushed out heater core 3

If the heater core is not damaged or leaking ie: if you don't see coolant on the INSIDE of your windshield or coolant on the floor inside the car then chances are you may just need to BLEED the radiator.

remove radiator cap

Fill coolant resovoir to the cold line if the engine is cold from sitting overnight.

Start engine with cap off

Wait till engine gets hot

While waiting you will see a big gurgle of air bubbles come out and the coolant level will drop

Fill the radiator with more coolant to compensate.

When the fans come on and it stops gurgling air install the radiator cap

You are done

Watch the coolant level for the next few days and top off in the resovoir as needed to keep it filled.

Your heat should be very hot now providing you installed the correct oem thermostat correctly.

Hope this helps

If it is fogging your windows, you have a leaking heater core. Dash removal is required to fix it.

My 1999 caravan is blowing cold air


Check the water Coolant level in the coolant reservoir and also remove the radiator cap, which tends not to be on the radiator any more and check it is full. Also burp the system by removing air licks buy sqeezing the radiator hoses when the system is hot. Remove the radiator cap before you do this. You also need to check the thermostat for correct operation as it might be stuck closed. Remove it, put it in a pot of warm water put it on the stove and you should see it open before it comes to a simmer.

You do not mention if you have chanced the thermostat or not. The thermostat is what controls the engine temperature. I have seen people replace the thermostat two or three times before they got a good one that worked correctly.With any luck the first one you put in will fix the problem.

I put a new thermostat on my 2005 grand dodge caravan yesterday, today I have no heat. Some said vapor lock, where is the air drainage on this model?


there is no air bleeder, It will bleed it self . Or you could put a pan under radiator to catch coolant spill, Put pan under radiator, remove radiator cap, start engine,let engine run,have a 50% coolant mix on hand, when engine warms up the thermostat will open and allow flow of coolant. just as the thermostat starts to open air will release causing coolant to spill over filler cap inlet, this is normal, the pan is so you don't waste coolant or make a mess. in a few moments as the thermostat opens to full position the coolant level will fall in radiator, at this time you will fill radiator untill it will take no more,put cap on radiator and use clean fluid you caught in pan or coolant in jug or whatever you have it in and fill the coolant reservoir to fill line. i hope you have heat now ! check reservoir again the next day, if low fill and you should be good !! do this procedure when engine is cold,never remove a hot radiator cap. but if you were too, make sure you squeeze upper radiator hose, IF IT IS HARD OR UNDER PRESSURE, DO NOT REMOVE !!!! If you can squeeze the hose then put a rag over cap and remove slowly a little pressure or coolant might spill but should be minimal. I have alot of experience in this and severe burns are possible to the inexperienced !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Cabin Heat is Intermittent / Fluctuates / Cycles


You may have air trapped in the lines to or from the heater core.
If you (still) have a real radiator cap on the radiator, remove it with a cold engine, start and run the engine allowing it to warm up while watching the water/coolant level. Make sure the heater control is set to its highest heat setting while doing this. If it is trapped air, you may see it 'belch' after the engine is warm and the engine thermostat is open. Refill as needed if this is the case.
It's more difficult without direct radiator access and may require several cycles of hot/cold to allow refilling through the overflow.

My heater in my dodge caravan does not blow hot air. When my engine finnaly heats up, it blows only warm air. Its a 2006


First of all make sure your anti-freeze is at specification level's as well as make sure With the engine cold start the vehicle remove the radiator cap and make sure you see the flow of anti-freeze while keeping your hands as well as your clothing away from moving parts feel both hoses going into your heater core if the one on top of hot one on the bottom is cold then you have a Clogged heater core in which case you will need to flush the system . a simple garden hose will do the trick simply remove Both hoses to the heater core with the hose at the bottom line apply the garden hose until liquid comes out at the top of the other hose will probably see a lot of gunk. Also ensure that the vacuum line to the round ball under the hood is connected and not dry rotted.this will cause a vacuum leak to not allow the switch to fully engage from cold to hot. I hope this helps you.

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.
