yesterday I replaced the water pump thermostat hoses and belt on my 2007 liberty, the water pump was leaking at the seal. Everything went fine but when I drove it it wanted to overheat so I bled it added more coolant and drove about ten minutes the temperature gauge stayed right in the middle where it has always been normally. Today I drive about ten to fifteen minutes and the gauge creeps up above normal. I was able to remove more air and I drove ten to fifteen minutes no problem. It sat for a few hours then I drove it another 15 minutes and same thing. I don’t know if there’s still air in the system, I have noticed that the recovery tank is a little below the full line or if I could possibly have a bad thermostat. Any help would be appreciated.
