I have a 2007 buick lucerne cxs it's overheating. I put in a new water pump and thermostat and a temperature sensor. It's still overheating but the tempature gauge stays in normal, there's no knocking, no steam or white smoke coming out. So what's the problem

How do you know it’s overheating if the temperature gauge normal and no smoke? Maybe you have air in the system?

CXS is the Northstar. If everything is looking good how are you determining it's overheating?
