Default COOLANT LEAK VS HEATER CORE

Hey Guys-

Here's a perplexing thought! Ive been on here complaining of what appeared to be a heater core problem-foul smelling misting coming through the a/c vents-some of you guys responded to my post and I appreciate that, but all the mechanics that have checked the truck( a 2000 Durango SLT)have said its not the core. Just this a.m I noticed the smell had escalated but only now I have a coolant leak from the passenger's side and a film like condensation has built up on the inside windshield. Could this have been the culprit all along? This sounds like theres a hole somewhere in my radiator hose-does that make sense? Any help would be appreciated!! THANKS!

I had the exact same problem with my 98 D (5.2L). Smoke with a horrible smell coming threw the vents, some foggy film on the inside of my car, and a bizarre buzz after driving for 5 minutes. I ended up taking it to a shop and they told me it was the heater core, so I had them replaced and now no funk. I would suggest taking it to a second mech for a second opinion. The heater core replacement cost me about 700 bucks if my memory serves me correctly.

Get under the truck, if possible.
If the coolant leak is comming out of a small (1/2" diameter) hose on the lower passenger side of the firewall, it's the heater core.
Everything you have mentioned in your posts about this problem points to a heater core.
Looks like coolant, smells like coolant, it's comming from the ductwork?
Only one way for coolant to get into the vehicle's ductwork. Wanna guess how?

Hey Duranged!!! Did my cheap little trick I suggested to you from your previous post able to pinpoint where the leak was??? The suggestion was go to to a auto parts store. Buy yourself a heater hose coupling. Coupling cost a couple of dollars. Then remove both inlet/outlet heater hoses going to the core and connect them to the coupler. This will bypass the core. Then drive your Durango for a few days. If the smell eventually minimizes itself or goes away, it is the core.

Now based on your present post, it is the core. There are no hoses internally within the core housing. It cannot be your radiator hose as that hose is located at the far front of your Durango and for it to leak enough antifreeze to reach your air vents and suck it inside to coat your winshield and floors, the leak would have to be super major. Problaby your Durango won't make it to the shop before all the antifreeze leaks out.

My heater core replacement costed me $650 bucks parts and labor. Good thing I have a great friend that is also a certified mechanic. But I feel sorry for him that it took him an entire day to tear down the dash and steering column just to replace a heater core. But the great thing that came out of all this, my A/C now freezes me really good during the summer time. I guess the baffle vent door may not have been properly aligned and after replacing the heater core and reassembling the box with the vent baffle door, my A/C can really cool down the interior on a hot summer day. I rarely take the fan speed setting past the second speed.

Is it a pain in the **** to DIY a heater core? I'm somewhat mechanically inclined, but wonder how much trouble it'd be.

My chargers heater core was a PITA to get too and in 1969 there wasn't the dearth of stuff to have to remove. Doing one now would be like climbing Everest to me, and that would take less time and less money.
