Coolant Smell and Heater (dreaded heater core)?

[Whelan]

So for at least the last year the Jeep has provided a smell of coolant through the vents when turning on the heat. It doesn't last but it is definitely noticeable, however the heat still cranks just fine. I read up and also noted that the interior windows seem to get somewhat of a foggy film on them after awhile.

So bottom line, am I looking at a heater core? There are no leaks, the heat works fine, it is just the smell and some film after several weeks on the interior windows. I'm wondering if a flush would help at all because I'm not sure how to properly diagnose if it truly is the heater core.

I'm not unfamiliar with taking apart dashboards and such although I know it will be time consuming to do for replacement, but can anyone advise on how else I could be certain this is my issue?

Unfortunately all of your description points toward a small leak & a core replacement.
Remove the dash end side cover & take a whiff, inspect for leak/wetness.
Pressure test the system and see if it holds.
Flushing at this point, may make it worse.
A stop leak is not something I would want to add/try either.
Proper repairs with new Hoat is the best route.

There are write ups, it's not that bad but not that great either...

Got my dash out in 45 minutes with help from pops. Granted I had the center console and seats out

Figured it was going to have to be done sooner or later before a catastrophic failure. I should probably get on it before the winter too.

Next question is the cost, I see them going anywhere from $20-$300 for the part on RockAuto and Advance Auto depending on the brand. Then Mopar has the OEM for about $125. Suggestions?

I'd just go Mopar if since it's within the price range of others.

I believe I got mine from Napa or advanced auto with a limited lifetime warranty.
