Hi I’m new here and I’m glad I found this forum and hopefully I can get so answers to very Confusing question. So this will kind of be a long post so plz bare with me, so I have coolant temp issue starting about a year ago the Jeep would start getting warm going up a hill I live in Colorado so hills are kind of big lol. So I never let get to red but it got close this winter I replaced the water pump and thermostat then just fill it back up and worked for the rest of winter but now it’s summer and the temp issue is back . I drained the system and used a vacuum tool to refill it this time so hopefully no air pockets. But it’s still creeping up in temp on hills under it’s own power (not towing) I had a temperature gun and took some reading and found out my lower rad hose is at 145 degrees going into the rad and my upper going into the thermostat is 185-190? So I’m at a lost. Has any had this same issue? And again sorry for the long post
