Coolant temperature gauge needle buried after one mile

Radiator/water pump/serpentine replaced this past summer. I can drive her about a mile and then I hear a rattling/tapping sound, check gauges light comes on and the needle for the coolant temperature gauge buries instantly and I need to pull over to and pop the hood to get her to cool down for five minutes before I can go another mile or so and only in lower speeds thirty to thirty five mph. Heater buys me another minute or two but she is sizzling from just behind radiator. Almost like nothing is cooling the engines. Jeep-experienced (Mopar engine) responses.
