2000 Dodge Durango water heats/ leaks trough upper cap betw

Couldn't see a clear leak or crack in the housing.

You have an either/or situation on this. Either the hoses are leaking past the clamps, the radiator cap upper seal is bad, or the housing is cracked.

I doubt that the housing is cracked.

The trails look to come from up high on the housing, so I'd think in terms of a radiator cap upper seal. By this, I mean the seal between the cap and the housing top lip, not the small seal at the bottom.

The other option is that the heat shrink clamps are a little loose.

Steam is hard to track, but the trails in the picture sure look like a bad cap to me.

Oldtech2, thanks for answer,
I've been checking and looks like the idea of heat shrink clamps is the one that's going bad here, water comes out trough the joints of hoses and housing, I changed that full hose-housing assembly once because of same problem, it lasted about 4 months and looks same, is this normal? Is there a way to fix without changing the whole stuff, first time I added metal-screw clamps, but I broke the housing. Now I changed the CAP anyway, but really water is coming out of those joints.

Take a good hot hair drier or a heat gun and heat the clamps up. Heat them as evenly as possible and they should shrink down a little more and seal off your leak.

My Durango started this on a much smaller scale and I managed to seal it by heating the clamps with my heat gun.
I've also had to replace the radiator cap due to the upper seal failing.

Another option would be to install constant torque hose clamps. They screw down like normal ones so be careful on the torque, but they don't loosen up over time.

I'd try the heat deal first though.

Good luck!
