Heater core or one of the hoses are leaking. Low on antifreeze now so no heat.

    So if I was correct with my answer to your problem then why would you give me only a help vote/score and not a Fix Ya? Short of coming and changing the core myself what other answer could I have given to get the top score? Just a thought , no big deal. Peace.

Smoke coming through vents temp. gauge going up acting like its going 2 overheat turn heater on hot and smokes bad turn to cool and smokes a little my husband thinks it's the thermostat and wants to...
If the heater core is leaking, you would get a lot of steam that would smell "sweet". That would also leave you low on coolant, which could be a source of your overheating. If it's more of an electrical smell, you may have a blower motor or a blower motor resistor going bad, but won't cause the engine to overheat.

It isn't heating correctly and i smell antifreeze. How do I check and replace a heater core in it?
If your heater core was leaking you would have antifeeze coming thru your vents and putting a greasy film on your windshield. You would smell antifreeze the stongest if it was leaking onto a hot engine part. low antifreeze will cause bad heater performance, I would check by the thermostate housing, and the water pump for leaks

95 escort smoke from vents vibration when accelerating why??
The smoke you could be seeing may be steam, your heater inside the vehicle may have a leak and causing steam to rise out of the vents, if you are smelling the steam this is what I suspect.
Engine vibration could be a number of things, check the engine mounts to start, one of them is probably broken.

Smoke coming out vents when defrost is on and temp gauge goes up and down in 1994 Taurus
The fluctuation in the temp gage indicates a low coolant situation. The smoke you see from the defroster vent is actually antifreeze that is leaking from the heater core somewhere and as the antifreeze evaporates from the heat it causes a vapor to produce. You should smell a very sweet smell when you see the vapor. If so it is definitely antifreeze. Find the leak and fix it. Then refill your coolant system to specs and you should be good to go.

Smoke coming out of vents
if it smells like sweet antifreeze, it is
the heater core is not he A/C evaporator core.

the core fails due to not replacing the antifreeze coolant before it goes acidic ... (not doing service here)

Antifreeze smell and smoke coming out of vents
You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

Bad smell coming from heater/ smoke coming out vents
I had the same problem in my 98 Dodge Dakota! Replaced the heater core, problem solved. No more funky coolant smell and erie fog coming through my vents. I bought the heater core at rockauto.com online. Have purchased many items now from them. All factory parts so far at half the price of even AutoZone, even with the shipping. Also, you usually have to wait only a couple of days depending on the part and they have EVERYTHING.
