The heater control valve is not opening and letting fluid into the heater core. Replace the heater control valve.

To do these replacements all of your antifreeze was emptied from the car. When system was refilled an air pocket developed in your system. This air pocket will have to be bled out. Take it back to where the work was done, have them bleed the system. GOOD LUCK FRIEND.

SOURCE: 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.

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: The heat in my 2006 grand prix will not get hot.

Are the 2 tubes that go to the heater core getting hot? If so, then the blend door is not opening to allow heat to get to the cabin.

Possible vacuum motor problem, either disconnected, or the controller for the blend door is broken is likely problem.

Troubleshooting by Symptom Poor Heater System Performance CAUTION
Check all fluid levels and adjust as needed, before operating vehicle for extended periods at idle.

  1. Start the engine.
  2. Idle the engine until the thermostat opens (upper radiator hose will be hot) Is the engine at normal operating temperature (approx. 200° F)? If yes, go to the next step. If no, go to step 16.
  3. Set the mode selector to FLOOR mode.
  4. Set the heater control selector to the warmest temperature setting.
  5. Set the blower speed the lowest setting.
  6. Carefully feel the inlet and outlet heater hoses at the heater core. Is the inlet heater hose significantly hotter than the outlet heater hose? If yes, go to step 14. If no, go to the next step.
  7. Set the mode selector to PANEL mode.
  8. Select the maximum blower speed.
  9. Select the warmest temperature setting.
  10. Place a thermometer into the center I/P PANEL air outlet and affix a second thermometer to the heater core outlet heater hose.
  11. Record the temperature at the center I/P PANEL air outlet and at the heater core outlet heater hose. Are the two temperature readings about equal? If yes, go to the next step. If no, go to step 13.
  12. Inspect and repair the cowl, cowl area, recirculation door, and the HVAC evaporator/heater core case for cold air leaks. Repair any problems found, go to step 17.
  13. Inspect the temperature door operation. Repair any problems found, go to step 17.
  14. Turn OFF the engine. Back-flush the heater core. Start the engine. Select the FLOOR mode and the lowest blower speed. Select the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Is the inlet heater hose feel significantly hotter than the outlet heater hose? If yes, go to the next step. If no, go to step 17.
  15. Replace the heater core. When the repair is completed, go to step 17.
  16. Check for low engine temperature problems, Repair or replace as needed, go to step 17.
  17. Operate the system in order to verify the repair. If the system operates properly, the repair is complete. If the heater still does not work properly, repeat the entire procedure.

2006 dodge grand caravan replaced thermostat and radiator, still no heat?? And the van is running hot


How hot is the engine in degrees F? With a fully warmed engine are the heater hoses, hot? Check coolant flow through the heater core. If no coolant flow through the heater or engine, I'd have to check water pump.

Sometimes when the cooling system is opened, it may get air in the system, your temp gage may be reacting to air in the system?

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.

I have a '03 Dodge Grand Caravan Sport AWD that the heater only blow hot air when going down the road. Van has a new radiator and new thermostat. Sometimes the blower will not kick on for a few


If the problem is a lack of air flow from the vents, and you suspect the blower motor is not running at times, you would need to test the blower relay and blower motor for power and ground when it is not working.

What causes an engine to get hot


Yes a restricted converter can cause an engine to over heat because it can't breath correctly so it make the engine work harder . Cooling fans not working is one of the most common causes for 93 to 95 dodge caravans over heating . their is a cooling fan control mddule located on the inside of the frame rail next to the radiator on the drivers side of the van that goes bad very often . Thermostat sticking is another fault that can cause over heating

I have a 2006 dodge grand caravan, when the car is in driveway idling the car wont heat up but as soon as you start driving the car, the car heats up normally. Should i replace the thermostat or is it...


The reason for replacing the thermostat is improper cooling - not heating. The purpose of the thermostat is to shut off the flow of coolant through the engine allowing the temperature to build. When it reaches the temperature it wants the thermostat opens and allows coolant to flow to maintain the proper temp. Dodge Caravans have a track record for maintaining a low temperature until the engine is at higher rpm. While it is inconvenient in cold weather it it not bad. However, you want to check that your radiator fan is shutting off when it is cold. A fan that is staying on when it shouldn't could cause the temp to stay cooler.
