I saw trace of dried up coolant on top of radiator, on driver side corner.
But when I looking at it, it is not leaking now.
But if I placed a cloth there. it gets wet with coolant eventually...

Could be "sprayed" there by the fan while running. Obviously a small leak somewhere. Usually you can find dried (or wet) coolant near the source as well. Use a bright flashlight and start hunting around all the hoses and the radiator. Pictures may help us point in a direction...

Yes, I should not jump on the conclusion that radiator is leaking.
Just found a (loose) small hose nearby that has trace of dried up coolant at one end.
So I tightened it a little bit, then placed a new cloth nearby to soak up any leaking.
The rubber hose probably is getting old and hardened, If no more leaking developed, will need to renew old hoses soon.

Thanks,
Karl

If the expansion tank has a breather, could have occurred during driving as mentioned above.
