I have had some luck with my two Durangos with 5 radiators splitting open between both of them. So let’s say I look over the radiator area often, I have been smelling some coolant for some time trying to find it in the usual places and I find this.
That's a pretty crazy history... where are you located? Is this somehow environmentally related? Are you in the desert or someplace very hot (or perhaps very cold)? Is somebody putting non-standard coolant, or anything else, in your vehicles or something? That's nuts!
Radiators split at the seams so I don’t know what’s the issue with them, I’ve seen others with same issue. I’m just super unlucky I guessI was thinking more of the 5 radiators and now a coolant overflow bottle, on just two vehicles. Something doesn't seem right. NYC can't be THAT hard on things, can it?
I had the dealer change mine outHello. I have a 2020 Durango rt. And my tank looks exactly like your pictures. Same cracks same spot. Did you replace the tank your self?
