Anyone experienced engine temperature dropping after changing coolant?

Hi guys, may naka-experience na ba dito na bumaba yung engine temperature after magpalit ng coolant?

Nagpalit ako recently ng coolant, and after the change napansin ko na mas mababa na yung temp reading compared before. Normal naman yung operating temperature dati, pero ngayon parang slightly lower na siya, especially habang cruising or nasa highway.

Okay naman yung coolant level and wala rin akong napapansing leaks or overheating. Possible kaya na normal lang ito after a coolant change, or baka related sa thermostat or may trapped air sa cooling system?

Anyone experienced the same thing? Ano yung naging cause sa inyo?

Thanks in advance!
