Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Okay, so if all those parts are new and in working order, then you probably have a flow issue with the radiator being partially plugged. This mean that the engine block is also partially plugged, so i recommend a power flush of the cooling system with a powr flush machine. Most shops have this tool.
