Question about 1995 Dodge Caravan

1 Answer

Smoke or steam coming from vents, not overheating, codes read 12 and 43.

I'm getting smoke or rather looks more like steam from the vents inside the van. Funny odor also noticed mostly when excelerating. The AC is working fine and the heat is working fine, fans are running fine also. Was mentioned it may be the heater core but I thought the heat would not be working if that were the case. I get diagnostic codes 12 and 43 and cannot seem to be able to find what they mean anywhere. Can someone please help? I just spent over 3000 putting in a new trans., struts and such. Van only has 80k miles on it.
Thanks

I think it probably is the heater core leaking.As the water eats up to boiling point small cracks will allow steam to escape. Probably smells like coolant.

Wath do that mean when your car over heat an smoke comes in the car when it do over heat


Are you referring to smoke or steam? If it's smoke then either oil or fluid may be leaking onto the manifold. If it's steam it could mean that the car is overheating and the radiator is letting off steam.

I have white smoke/steam coming from my air vents and antifreeze leaking from a spout in my firewall. Any ideas/solutions?


Your heater core is leaking steamed antifreeze into the vents and possible out the firewall,where the heater hoses connect to it. Have that checked out.

Gray smoke coming out of tail pipe 2006 bmw 750li


It sounds like you may have overheated your engine or the cylinder head gasket is leaking. The grey smoke is normally due to coolant getting into the combustion chamber and being turned to what looks like grey smoke but is actually steam. Check your coolant level and if it is dlow this will be your problem. The only way to correct the problem would be to have the head gasket replaced.

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.

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 when braking!


Is this smoke or steam if it disapates quickly it is steam (which means you either have a water leak or are overheating) if it is smoke it will hang in the air much longer this could be something as simple as a valve cover leaking, a brake line leaking and hitting your exhaust manifold

Smoke from the vents after upper heater hose replaced


Smoke through the vents indicates a heater core issue. If you are losing coolant and / or getting coolant inside the car (check the floor boards) this would tend to confirm a heater core. Best of luck to you.
