[IAN]

I have a 72T 2.4 w/MFI that runs hot. No front cooler.

When it is 80 degrees out I can see temps of 250 when driving at highway speeds. This problem really only occurs when I'm driving at highway speeds or during 'spirited driving.' When i'm driving around town or in traffic ironically it doesn't get very hot, around 210.

So really it gets hot under load.


I have tried:

1) confirmed ignition timing
2) had oil cooler removed and cleaned professionally
3) removed debris from top of engine. There was a mouse next on the left side of the engine that I removed with no improvement.
4) I have pulled out the thermostat and boiled in water and it did open at 180 degrees. I was ready to replace it but didn't once i tested the one in the car.
5) confirmed that metal cooling pieces are in place correctly
6) confirmed seals are decent around perimeter of engine.
7) replaced temp sending unit.
8) oil tank has been removed cleaned, tested, etc.
9) read all of the posts i can on the subject of hot running cars

What's left?

Is it possible that oil lines get clogged? I guess i could pull the hard line that runs from the bottom of the motor.

Could my thermostat function correctly in a pot of water during the test by not work in the car for some reason?

I'm not sure what else to do and it driving me nuts.

Any ideas?

Thanks.
