Hi, sorry for the late reply...
At the end radiator was leaking, but only at very hi temperatures...
Ordered a new OEM radiator, OEM Termostat, Toyota OEM Coolant, and problem disappeared... No more overheating... On any circumstance.
Took good time to extract all the air, even the heater started to blow warmer than before.
Crazy, but after these service, I have the feeling that the Jeep increased a little bit it's power output...
Made peace with the Liberty.
( Water pump replaced OEM in 2017 )
It's about to hit 160k on the ODOMETER.
Regards,
