Will my KV6 develop into an overheat problem ?

Hi veterans,

Pardon me a naive question.

My KV6 2.5 runs fine. Except one thing puzzled me a lot.

Background: '99 Longbridge built. Head Gaskets are healthy, 3-speed fan works well, aircon fine. no airlock, heater blown hot, no coolant leakage. thermostat status unknown.
Ambient temp: ~25C.
Temp monitor: via IPK or OBD port.

No matter the car run in highway, in traffic, uphill/downhill, the temperature rise to 102C and stay +-3C around there.
Fan turns on at 100C and stay on all the times.
Water circulates (at least) on the bleeding hoses of the tank.

Top coolant hose is red-hot.
**Bottom coolant hoses (and radiator) are just cold / lukewarm.

Does anyone encounter the same ?
Was the thermostat likely stuck ?

Many thanks for your help & opinion.
