Overheating!!!!

[chevy man 33]

I've changed my engine ,transmission, thermostat, fan clutch, radiator, water pump , and burped the system I have a 2013chevy silverado 2500hd 6.0 does anyone have a suggestion what else I can do ? No check engine light

Also changed the temp sensor

Define overheating.

 

How hot? Are you using the gauge cluster and using a scan tool to verify temp?

 

Have you tested the coolant for exhaust gases, which would be a head gasket failure.

[chevy man 33]

Yes using the gauge cluster.  Temp goes to about 210 as it should then about five min later goes around 220 . no sir not using a scan tool . I wouldnt think it would be a head gasket cause that's why I replaced the motor from the previous one .

220F isn't "technically" overheating.  Overheat warning doesn't kick off until 265F.  

 

Why did you change all of those items to begin with?  Engine failure?  Transmission failure?  

[chevy man 33]

Just cause the truck kept over heating mechanic recommended it

Top hose of the radiator is getting hot but bottom hose has no pressure nor getting any kind of heat to it

The mechanic I used recommended it . I have spent a fortune on this already and have the same symptoms. He stated it was a blown head gasket and my Transmission burnt up as well cause it ran hot and started shifting wrong .

How well do you know this mechanic? Are you sure the parts that have been "replaced" were replaced? I don't mean to sound negative, but cooling systems aren't very complicated, and if the mechanic's solution is to keep throwing parts at it, then it might be time to find another mechanic.

 

Lastly, as newdude stated 220F isn't overheating. If I remember correctly most engines will run between 195-220F.

Drill another hole in the thermostat, if that doesn't cause the temps to be much lower, I have no idea what else is going to fix your problem.

Check the heater core for problems, if your heater is not blowing hot air properly, the heater core may be clogged and restricting coolant flow.
