So when it hit 90 degrees outside the other day and right before I was going to go camping, my jeep overheated in the chick fil a drive thru. I thought it was low coolant because I know I have a bad heater core since it’s been slowly leaking through the a/c drain vent tube. There was no coolant in the overflow reservoir so I began to open the rad cap slowly and let the pressure out and when I thought all the pressure was out I opened it up fully and it spewed out like a water fountain. Then, of course the coolant was low so I had a friend pick me up to get some more coolant and I filled her up but my jeep overheated again. I pulled over and replaced the thermostat with a regular 195 but it overheated again. I replaced the waterpump and now my temp is reading just above 210 which I know some people say is fine but my worry is that it’s reading just above 210 on a cool day. What about when it’s hot again. Before ever overheating my jeep sat DEAD ON 210. Is it a bad temp sensor or maybe a bad thermostat?
