Smoke From Air Vent on my '67

[<rls9151@xxxxxxxxxxxxx>]

 Setting the temperature at the lowest setting will, indeed, restrict the coolant flow but, there will still be pressure in the heater core. It will still leak. The only way to stop the leak is to bypass the heater core (connect the hoses to each other and back to the engine). Generally, if the heater core is leaking and there is coolant in the system, it will fog up the windshield.

 Heater cores are relatively inexpensive but take some skill and time to replace.

Don;

 

My 55 has a leaking core as well. It's leak is evident on the firewall side. The firewall below the heater housing is damp with coolant. There was no indication of glycol smell or wet carpeting inside. The coolant flow to the heater is controlled by the temperature setting. With the setting at the coolest position, the valve restricts coolant flow to the heater core, and you will not lose coolant that way.

 

Check out the firewall side for moisture below the heater housing.

My problem with the heater core theory is: 1) the heater was "off" when I observed the "smoke".  2) when the heater was "on" and I was losing coolant onto my garage floor none was on my carpet.  Wouldn't a leaky core leak onto the carpet?
