What would cause white smoke to come out of heater vents?
Most likely the heater core is leaking. If there is also water on the floor and an antifreeze smell in the passenger compartment, those are also signs of a cracked heater core. Also, GET THAT TEMP GAUGE FIXED!!! You could be overheating and not even know it. Once the motor overheats, you're risking a blown head gasket, a VERY EXPENSIVE repair, or even worse, a blown engine. If steam is coming out of the vents it is very possible the motor is overheating. You need two repairs, your heater core and your temperature gauge.
My heater core was replaced since it had a hole in it. The blower was also replaced but with a used one. The guage is now working and so far, no more white smoke. Heater does not get hot though and the blower motor is very loud. Hey, ya gotta laugh a little...from one thing to another. I suppose the worse thing is over. Thank the Lord though I did not have a new car since the guy that worked on it did a number on my dash.
Symptom: on a 2000 Ford Contour, white smoke came through the vents and the smeel was acrid. We switched the car off. A few hours later, the car was fine, no more smoke, but the heater didn't work on one speed setting.
Solution: there is a resistor block which controls the blower speed in the ducting. When one of the resistors goes, white smoke is fed dirrectly up to the vents. Replacement is easy (admittedly while doing a head stand in the passenger footwell) and fairly cheap.
Suggestion: many other cars will have a similar layout. Check this out before investing in a new heater core...
My 1998 Durango is blowing white smoke out the vents and moisture on the windows but it is not antifreeze can anyone tell me why?
I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.
That is probably antifreeze steam. Your heater core is a small radiator used to heat your car. The engine heats the antifreeze and circulates it through the heater core. Your blower blows heat through the core (radiator) into the car, and warms you. If the core gets a small leak, it will put out steam.
== == Could possibly be a heater core leak. Coolant is getting blown up through the vents when you have the heater on. May need to do a heater core check and replace. if you have the a A C on it means that your A C freon its leaking, also if you run the AC on with one window open it will create smoke fron the humidity coming in to the car if it's…
What is wrong and what should be done if a car emits white smoke from the air vents even if AC and heat are turned off?
Fine white smoke coming from air vents in a 1998 ford expedition with an oily substains on drive floor also same substains comes out of floor vent. What could this be?
White smoke after start up from a Chevy big block also your heater core went out on you and is leaking?
If you 1968 Ford sometimes shunts smoke in through the cab of your car and it smells like antifreeze but you think it might be CO2 what can you do?
You may have an exhaust leak that is coming up through the bottom of the cab. Burning antifreeze smells different than anitfreeze in the bottle--burning antifreeze smells somewhat sweet, when i was a kid i thought it smelled like the doughnut shop. Burning anitfreeze will also make white smoke, and your coolant level will always be going down. It is often caused by a leaking head gasket. CO2 is carbon dioxide. I think you might…
Why does your heater only blow hot air out the defroster and not out the vents in the dash 1987 Suzuki Samurai?
Antifreeze smelling white smoke or fog coming from the vents means you have a leak in the heater core or one of the connections to it. This will only get worse and needs to be repaired before you loose all your coolant. If it smells like burning leaves or grass then it is possible that leaves have found their way into the heater box. A lot of vehicles use a resistor block that is mounted…
Bad spark plugs and leads can commonly make the engine feel like its 'hesitating' or skipping a beat, often worsening in the higher rev range. However it is not the cause of white smoke. White smoke is typically associated with coolant getting into the combustion chamber. The most common cause of this is a cracked head gasket, which you will need to replace in order to rectify the white smoke.
Can a bad oxygen sensor cause overheating and white white smoke from the exhaust on a 1992 Honda civic?
Why Would White Smoke Come From the Passenger Side of a 1995 Jeep Cherokee..faint smell of anit-freeze?
Several reasons come to mind: 1. the heater hoses are on the rt side & possibly could be leaking hitting something hot & burning off. This would cause white smoke & scent of Anti/freeze 2. A leaking heater core dripping through the evap drain & hitting again something hot will cause burn off & scent. 3. A leak in the cooling system anywhere will cause this problem. I suggest a simple pressure test of the…
