My car overheats within 5 minutes of driving. the temp stays at normal for a few minutes, then it quickly overheats.
What I have done.
Changed the radiator.
Changed the water pump.
Changed the thermostate.
Changed the fan clutch.
New Coolant.
Bleed the system a million different ways, took out bleeder screw, raised reservoir tank, used a hose and poured coolant in through the bleeder....Needless to say, I made sure there was no air in the system.

I have no idea what else to do.
Any help would be super appreciated.

 

Pressure test the cooling system and do a combustion gas test on the cooling system.

you might have a blown head gasket.

also, post in the discovery 2 section, you will get more help.

 

Also please define what you are referring to as overheating - my 04 went to 215.6 once and a while.

That is hot but not overheating - if you are going to the red in the gauge after all of that your best bet is as abran suggests.

Also rad cap - the one on the expansion bottle you need pressure if it is not holding you will have problems.

 

Cap good idea and do the recommended tests.

Going by dash gauge/light or do you have a OBD II reader to check for more accurate temp measurement?

Have you checked intake manifold at temp sensor with a IR temp gauge/gun to verify sensor reading correctly.

Did you remove block drain plugs and flush engine well when other work done?
......

 

Yes, first thing you should do is verify actual temperature...with a independent mechanical gauge or IR gun. Does the engine smell extremely hot and are you loosing coolant when it "overheats"? You could have a bad sender or gauge, if it doesn't smell "hot" and you aren't loosing coolant.
