Not Overheating, Smells like really hot antifreeze after I drive, a/c ok heater heats but when stopped air gets cold...stummped..thermostat?, Leak?


check your hoses and make sure its not getting low because when it gets low the hoses can get hot enough to expand and spit out antifreeze without overheating

I have a dodge 97 dakota, my heater doesnt blow out heat after warming up and being driven, and sometimes i kind of smell antifreeze, when i use the defroster


it sounds as if you have two problems,one the heater core is plugged and two you have a heater core that is leaking.the leak is shown when you use the defroster by the smell and chances are there is a light film of antifreeze on the windsheild.and the plugged heater core is shown by no heat.check the radiator to make sure the coolant level is full and the overflow bottle is at the full level. as a low coolant level in the radiator will cause no heat.with the car warmed up(radiator coolant hot), check the heater hoses at the firewall were they enter the heater core they should be the same temperature from one hose to the other.if the coolant level is up and the hoses are the same temperature then the heater core is plugged.if the coolant temperature is the same from hose to hose but not hot to the touch the thermostat may be weak and needs replacing.either way the heater core will need to be replaced as it is leaking into the heater box assembly

The heater is only blowing cold air.


The first thing to check is the level of your antifreeze (engine coolant) If it is low, the heater will not have any flow of the hot coolant to heat the inside of your car. If the coolant level is low, you need to find out why it is low. The coolantis in a sealed system and you should never have to add any to it. The only way it is going to be low is if there is a leak somewhere in the cooling system.

If the coolant is not low, the problem could be a bad thermostat. The thermostat controls the flow of coolant through the radiator and thus keeps the engine at operating temperature.

If the engine is at operating temperature and the coolant level is ok, then you probably have a problem with the blend-air doors or the controls for them that adjust the temperature of the air coming out of your heater and vents.

The heater will only blow cold air. THe engine is warmed up but no hot air is being produced. What is the problem?


Start simple, check the coolant level, if it's too low, hot coolant won't reach the heater core, resulting in no heat. If the level drops further, the engine overheats. So check the level 1st, if it's ok, what does the engine temp gauge indicate? Is it running cold, normal, hot?

No heat is coming from the vents.The heater fan works normally. There does not appear to be heat recirculating through system. When in stop and go traffic the heat indicater gauge goes to hot. When the...


when the level of coolant drops in the motor the heater core is the first to be without
because it sets up high
so you need to check the level
and check where the coolant is going
to make the level drop

My 2003 dodge ram 1500 truck stopped heating. Cool air is all that comes out.


low radiator coolant level OR bad thermostat and Lord I hope not,a leaky heater core.Check fluid level first the look at thermostat replacement only after the level check. Good luck and bless you in advance if you should catch a cold...from the cold!

Warm heat not hot


Check antifreeze level, if it is low coolant may not flow through heater core. If coolant level is ok feel the heater hose with engine running at normal operating temp and heat on high, if one hose is much cooler than the other you have a bad heat control valve or a pluged heater core.

Why doesn't the heater blow hot air?


If your "Check Engine" or "Service Engine Soon" light is on, you need to have that checked out first.
If not, the next thing you should check is your engine coolant level. (Antifreeze) If the coolant level is low, the engine coolant does not circulate through the heater core and the the heater doesn't work. The coolant level could be low for a number of reasons including a leaky hose, water pump, or head gasket. In any case, if it is found to be low, you need to find out why.
If the coolant level is OK then the thermostat function needs to be checked to make sure that the engine is reaching operating temperature.
If all of the above checks out OK, then the heater control valve and/or the blend air door in the HVAC housing needs to be checked for proper operation. (NOTE: some cars are not equipped with a heater control valve)

The heat in my 2002 hyundai sonata doesn't work, Help!!!


Is the fan working and blowing air but there is now heat?

If there is no heat and air is blowing out check your radiator level. If the engine coolant is too low water will not get to your heater core. Remeber check the radiator level and not just the coolant reservoir. Becareful when working around a hot car. wait til the car cools down to check the level of the coolant in the radiator.

No hot air FROM HEATER inside 2000 318IA


Hi There, If the fan blows only cold air, then you might have a restriction on the heater core. The heater core is like a small radiator inside your dash. The coolant flow through it can be restricted by corrosion. The lack of flow of coolant through the heater core will result in a lack of warm air inside the car. Flushing out the heater core may help. If not, you will have to replace it. I would say though, 80% of the time the cause is just restriction. Get the heater core flushed and I am sure you will get your heat back. MIke
