1991 Dodge Dakota: smoke coming from air vents

I am getting smoke coming through my air vents. I don't know if it is coolant or just motor oil. To "trouble shoot," I replaced the exhaust system, as I thought it was exhaust. The problem still occurred so I got the oil changed, Put a quart of oil stop leak in and still smoke pouring through. A day ago I had the radiator flushed and checked for coolant leaks. We found not evidence of a coolant leak. Perhaps, I have a leak coming from the seals or the head gasket that is leaking on the block?

    Is there smoke anywhere else coming from the engine?

    There is a resistance coil in the heating duct for the fan speed control, and if it is full of junk from stuff that accumulates, maybe that is smoking. Make sure the AC is draining out properly.

Heater core must be leaking. Turn it on defrost and see if the windshield fogs up.

Smoke coming through air vents


Is it smoke? Or is it steam? If it's really smoke, it will smell like burning wires and you have an electrical short somewhere. You're going to have a fire unless it's fixed.
My guess is that it's probably not smoke or you would have already had a fire.
With that said I'm going to say that it's steam in which case your heater core (which is a small radiator located under the dash) is leaking coolant and the resulting steam is rising through the vents. The steam will have a sort of sweet and yes, a steamy smell to it. It will also leave a funny film from the radiator coolant coating the inside of the windshield.
The heater core should be replaced if my assumptions are correct.

Dodge dakota 2005 -check engine light(gas cap)gas cap was replaced.Fuel spills out when filling tank.Fuel lines were smoked and no clog was found.


There is a check valve in the filler hose to stop fuel from coming out seems yours might be stuck , run a metal coat hangers inside the filler neck while prying open the little fill flap. see if that helps OR you are not or have no VENT to AIR in your evap system causing excessive tank pressure.

2001 dodge durango have replaced cooling system neck-vehicle is building too much pressure blowing coolant out of filler cap-could it be thermostat causing problem?


Have you "burped" the system to get all of the trapped air out?? If you have the 4.7 motor, it helps to slightly elevate the front of the Durango.

Then, leave radiator cap off and start engine. Watch coolant level and open the system vent which is right off of the upper hose connection.

When air ceases to come out of the vent, secure it and top off coolant.

It helps to run the engine rpms up to 2-2.5 k in short bursts to help get the air out.

Make sure to have both front and rear heater systems on full heat during this process.

With AC on I get what looks like smoke but it is more like steam thru the vent,on the vent is oily residew but doesn't smell like coolant?


coolant isnt oily.
sometimes white vapour (condensation) may visualy appear when first turning on the air conditioner, and that's normal.
oily residue isnt. no idea what it could be.

1991 Dodge Dakota dies when shifting from park


If it runs down highway fine, but just stalls when off throttle, turning, heater on, etc., I'd pull I.A.C. motor off and clean with throttle body cleaner & retry it. Clean port it came out of at same time too. if it cures it even temporarily, and does it again, replace IAC motor.

Heat blows "smoke" from vents


you need to replace your heater core... the smoke is from antifreeze getting into your blower motor .........
