94 explorer running hot?
Its a first Generation I have had about a year, had some of the typical issues with a vehicle this old---bad connection with a relay under hood, cracked fan blade, IAC, nothing I could not find.
Temp (issue is getting worse) runs up to high end of "Normal" yet I note radiator does not seem overly hot. (to the touch).
Antifreeze tests very good and is full---no signs of leaks or liquid in the oil.
I am hoping thermostat or radiator===vehicle has been well maintained and does not show rust in the coolant, and no signs of leakage around the pump or anywhere else---coolant level does not drop.
I have got some good help here before so-----
I am planning on removing the thermostat and seeing if same issue with it removed====it should rule that out or not----
Any advice appreciated.
Keep in mind it is not boiling over but just running towards the high end of the normal area.
Thanks in advance for any help

It could be a stuck thermostat or a plugged radiator (low flow)...
Back flush the system and change the stat.
the larger concern would be the A4LD transmission, they do not do well when run hot.........Philip

Thankfully replacement of the Thermostat and the odd gasket it uses fixed the problem, only one of the three bolts (which is in a tight position) gave me any problem.
The old Thermostat shows signs of both heat damage and the pillar was warped as well.
thanks to those of you who took the time to reply.
