Coolant vapor/steam from heat vents

[dirkdiggler]

Hi guys,

Is there anything besides the heater core inside the dash that can leak coolant causing coolant vapor to come from the vents when the heat is turned on??

Its always a really good thick blast of it when I first turn on the blower and then seems to go away or be much less noticeable. .....can still smell it though.


I replaced my leaky heater-core with a good used one from ebay last fall but just wondering if there is anything else that could be leaking ..... or if the used one I bought is also leaking.

The used one I bought looked like new so I find it hard to believe but I guess it could be leaking......????

Did you check the hoses too?

perhaps not as good as I should have.
