For oil, semi synthetic or mineral 10w-40 or above oil grade.
For Coolant, ZIC or preferably, Caltex all the way! 
Pour coolant after complete flushing of cooling system, and radiator service (preferable).
Ensure that Thermostat Valve is installed and fan is on Auto. Also replace radiator cap in the end.
I hope, it guides and helps. Thank you.
