Don’t take this wrong way has it boiled to the point of really overheating , steaming etc Or are going by temperature gauge. or any chance faulty stat , if you put it in a pot and pour over hot water can you see it opening ok.
Trying to think of something not serious ie temp sensor etc.

Thank You for replay.. The pressure causes radiator broken and water leak. Many technicians said this issue from head gasket.

So is water showing in the oil when you dip it , I would definitely check thermostat is opening or even take it out completely to see if it starts to build up any pressure , but it may well now be head gasket.
