Burning coolant smell?
whenever I accelerate heavily or sometimes just turn my defrost on, I see this smoke coming from my vents and it absolutely reaks of burning coolant. anyone know what's going on or how to fix it?

Where is the heater core?? I took a look under the hood and didn't see any leaking anywhere... and the Radiator is only a few months old.

Heater core is under/behind the dash. Dash must come out to access the heater core. If a/c is still working, might as well replace the evaporator a well. Dash must come out for both.

Crawl under the dash with a flashlight. If it's the heater core, it will eventually leak enough to drip coolant on the passenger side floorboard.
