Heater core Replaced but still stinky??

[curtc]

I had a heater core replaced in my Dodge truck last year (at the dealer) the smell from the leaking one took a long time to dissapate. Maybe several months...

When I replaced the heater core in my Cosworth I ended up pulling back the carpet to dry it out for about two weeks by running the heater on full whenever I could. Extanker brought up a good point, did you have your used core tested? Hopefully it's not leaking.

might also be a good time to replace the cabin air filter.

The cabin airfilter is just under the hood on the passenger side right? under the windshield wiper? I did replace that if that is in fact the cabin filter.

I really hope there is just some coolant in the air ducts rather than the used heater-core failing already
