Help! 2002 QX4 Overheating

[audley1972]

Hello all.

My '02 QX4 is overheating.

I changed out a leaking radiator, thermostat, belts, hoses. etc...

Followed the recommended process of draining, filling, burping closely and still I am getting a hot upper hose and a cool lower hose near the radiator.

I am also not getting heat from my vents. Heater core hoses are cool as well.

Any help/advice/direction would be greatly appreciated!

Thanks in advance.

Thanks Rogue One. My second post was a bit of Pink Floyd humor. I've been working on my own vehicles, too many too list, for about 20 years and have yet to run into something quite like this. There is air in my coolant system and I have scoured the forum and have tried a few of the remedies that made perfect sense and was hoping to find a simple, time effective solution. May just be patience or lack thereof that is the culprit here. I'll keep on burping.

Patience paid off. Great machine. At 195k still super tight.

You got the air out? Or was it a blockage?

I was sitting around on my butt for too long and was getting comfortably numb in the a**.
Anyway, I was just wondering, who is this Mr. Floyd you speak of?
