Air is trapped in the heads. Park the truck on a hill, front end higher, remove the air bleed hose at the front of the head, pour coolant into the reservoir until a steady stream of coolant comes out of the head steam crossflow coming from the head.

You have verified the cooling fans are working of course? And blowing the right direction?
+1 Make sure the polarity of the fan isn't reversed. and make sure the fans are on the correct side of the rad.Another issue could be the 160 stat. It may not be slowing the coolant down long enough to cool it. I had that problem in my 3rd gen TA. Put a cooler t-stat and the sock fan wasnt strong enough to cool it because it didn't stop the water long enough.Originally Posted by Oldspimp

Red I will try that as soon as he gets the truck back over here.
As far as fans they are installed properly and pulling air.... And very effectively at that. Once I verified fans were working correctly (also cant be the kicking on properly as they are hard wired to come on with ignition) I thought maybe it was the aftermarket t stat. But it was doing it before hand with the stock one as well.

Shoot different parts of the radiator with a temp gun. My 99 had the EXACT same prob and the radiator was clogged with mineral deposits. Something easy enough to rule out. I tried flushing it prior to the diagnosis and it didn't help.
I've mentioned this as well. Note he swapped to a new 2 core radiator. Thinking his original unit was messed up...
Never hurts to try. Drive up to the parts store and borrow one if he doesn't want to buy a temp gun.
looks like youve had this problem

The difference between winning and losing, is having a 2nd stage.
Think thats kinda like burping the system if not burped during fluid change right? cause air rights like a burp hints the name... Wonder if the fans are patched right in the tune tho?
