Over Heating Problem 2003 Discovery

![Default](https://landroverforums.com/forum/images/icons/icon1.gif)
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.

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.
