There is a tap or valve on the heater or hose that controls the hot water to the heater radiator, make sure this is working and not closed or broken.

SOURCE: Coolant filling up overflow bottle

You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.

SOURCE: 2002 3.5l limited is overheating. Change

Not sure about this car. However, most times the thermostat is located on the motor where the main radiator hose connects to the motor. You will have to remove the hose to find out for sure.

To prove the valve that gives water pass towards the heating if this one does not open you have no heating inside the car

SOURCE: 2001 eclipse no heat

Stick your head under the driver side dash and look on the side of the blower motor check to see if the wire to the damper is moving through the small plastic conduit. over time the wires lose their rigidity and instead of moving the damper it will bend. Let me know if these look normal

SOURCE: I have a mitsubishi space wagon (not galant but

It sounds like the water pump belt under the timing belt is broken or the pump is not circulating the anti freeze the way it is supposed to.Did you replace the water pump, water pump belt, and timing belt when you replaced the head gasket? If a vehicle is over 100,000 miles it is recommended to replace the water pump while doing the timing belt just because the pump is such a pain to get to under the timing belt.

1999 Dodge Dakota V6 heater problems! I flushed the heater core, did not help. I tried putting a T in top heater hose, connected the hot side heater hose did not help.

Question edited for clarity and fix the text and add some spaces.
Question moved to model category.

This is usually cause by air locks. When you have air in the system, the heater core doesn't fill with coolant and doesn't circulate. If you add coolant and you are on a driveway with the front of the vehicle down a few degrees, the heater core doesn't fill.

Another outside possibility is that the impeller on the water pump is worn out.

Couple of thoughts. are you losing water/antifreeze, do you have the right mixture 50/50 water/antifreeze. You did not say if the thermostat is removed or replaced. If thermostat is stuck closed water will no circulate. Are you getting any flow from the water pump. If your heater core is bypassed you should not get any hot air from the heater in the vehicle. Make sure your oil levels are good.

Stacey
sounds like your blower motor is OK so either the hot water is not getting through the heater core, or the air is not being routed across the heater core. If the hoses or core are blocked, that would do it or if an air door is not allowing the air to the core.

Hopefully it won't come to core removal, but this video should illustrate what is going on. There are also videos for unplugging the core. good luck

1 check,Feel the heater hoses,do they get hot ,both or one?They should be hot,if not flush the heater core directly with a hose,back and forth at each hose connection.
2nd check,clamp off the top rad hose and force the hot water through the heater and check heat output.If there is heat with top rad hose clamped change the thermostat,it's either leaking or defective,new or not.

Truck blew upper radiator hose changed that and thermostat still over heating think its air bound any way to bleed 2001 dodge dakota

remove the radiator cap, leave it in park, start up and let it idle. turn on the heater so the air gets out of the heater core. give it 15 or 20 min. after it reaches operating temperature. if needed, do it again. also remember your thermostat may be bad

May be a plugged heater core. OR Someone removed your thermostat to cure you overheating problem. Remove heater hoses , (in and out hoses) leading to and from heater core and try to blow through it. DO NOT clean out using more than 16 p.s.i. as this will burst you heater core.Also check to be sure heater flap is opering to let heated air into cab.

1996 Dodge Dakota heater doesn't get very hot only gets warm

it could be the heater controls itself i had a 95 ford f150 that did the same thing i replaced everything i could as i live in upstate ny and in the winter it gets pretty cold so replaced all i could ,heater coil,radiator,thermostat,coolant and nothing a local mechanic told me to check the control in the dash to see if it was going all the way to the hot position. i took the dash apart to get to it and checked it and the cable that mmoves the valve on the heater coil was stretched so it wasnt going all the way to hot. not that its the same thing but its a place to start
