Good afternoon,
Are the cooling fans working when it is at idle? If they are not, it will overheat at idle and not at higher speeds.

I just brought a brand new fan and it still does it.

Okay, do you have a voltmeter or test light to do some testing?
I attached a diagram of the system. Check the two fuses listed for power on both sides with the key on.

Sometime it says Stabilizer off, then overheats when parked.
