Hi I’ve read so much on this that my head is still spinning! I have a 01 3.5 path le, last year I had same problem I changed water pump, thermostat bled the air out of block and in the end everything was good. This summer it started again and I replaced the thermostat again. Bled the radiator and it’s still overheating or should I say the radiator keeps boiling over into the overflow res. I just noticed that the upper rad hose was solid and hot, the engine doesn’t appear to be very hot and the lower rad hose seemed empty and cool. It sounds like a clogged rad but it appears clean. Help!!!!!
