im not sure how long its been doing this but the when i turn the heat on in my 86 smoke comes pouring from the vents. i shut it off and it still just keeps commin. it might not be smoke tho, it seem more like dust. what can i do about this?

 

just turn it on high and let it blow itself clean

 

"smoke" coming from the heater vents is a sure sign of a leak in the heater core! it's coolant vapor you're seeing and it will leave a nasty deposit on the windows too, so you need to get it replaced or bypass the heater until you can fix it.

 

i dont think its actually smoke i think its just dust but ill have to check it out when i take her back out in the spring
