Hello, I am new to the site and wanted to say thanks to all the great information that I have already been finding. I did want o open a discussion about a faint to strong coolant odor that is in the cabin of my Commander, I have checked all of the heater lines that enter the cabin and have found no issues. I have also had my mechanic look into the issue with no results. Was wondering if anyone else has the same problem.


Thanks

Did you check the T-connections located under the hood near the firewall on the heater side. They a tendency to get small leaks.
Yes, there was a small leak on the intake connector by the firewall. I thought that it was just residual smell left behind but that was over a year ago.

Hey there,

i had the same issue awhile ago (the smell was like stepping into a maple syrup factory and it also would fog up my windshield) i found that it was leaking at the T-connections and then also at the heater core. I lifted up the carpet on the passenger side and saw that it was wet, i then set a paper towel on it and saw that it was green coolant.

I'm not saying that this is your issue however, you may want to check the passenger side floor.... just to be safe. If you find that you need to replace the heater core, it is a pretty simple job if you make 2 small modifications.....on the 5.7 hemi anyways.

NP. From what i have learned....if your window is fogging up and its warm out and if the passenger side floor is wet....then that is a sign that your heater core is leaking and you'll have to top off coolant in the reservoir tank every couple of days.

Let us know what you find out...
