dear Xulfiqar
thanks for your interest, well u r right, i didn't check it by touching, let me explain,
as u know honda city idsi doesn't have gauge indication, it has lights green @ cold and red @ hot,
before few months when i used to start my car in the morning green light used to take some time to be switched off,
but now its switching off too quick,n water of car also reducing(not too much frequent) not even now, in winter too.
