Hi Guys!
I need your help
I replace the thermostat, new lower rad hose, new water pump
check clutch fan and seam to work fine
and still overheat.
I remove the burp plug from the upper rad hose housing
and fill with new anti freeze till it come out.
place thermometer in radiator and run engine with heater on full blast till hot air came from heater.
thermometer reach 195 200 degrees burp bleeder screw til no bubble came out.
I do not see circulation from coolant in radiator????????
No white smoke from exhaust pipe so no problem with head gasket
no engine missing run smooth 154 k.

What could be to overheat????????????
PS no error code from pcm
Thanks

 

PG:
The 4.7 cooling system can be a bit of a bear to "burp." It helps to slightly elevate the front end a bit, and then with coolant cap off and engine running with heat on high, top off system with bleed screw open and the throttle several times to 1.5-2K to get the coolant moved aound and the air up and out.

This process can take 25-35 minutes. Once you have just fluid and no more air from the bleeder, close it.
Top off, replace coolant cap, and take a good 10 minute drive while watching the temp gauge to see that it stays in the proper range.
