So my 2014 durango 5.7 had two leaks, the waterpump and the radiator. I replaced both and also the thermostat, but it still oveheats within 12 min. My upper hose gets hot but not the lower hose. Any suggestions on what could be the problem?
Yes or at least i followed the procedure i found online. What also concerns me is within a minute or two the system pressures up. I let it run to get things moving then shut it off and when i open the cap slowly its already pressured up and spills out.
Sounds like you gotta blockage somewhere between the upper and lower hose possibly I pulled my upper hose out and there was gunk built up causing mine to over heat changed or the hoses worked just fine afterwards
