Do you have a thermostat?

Besides regulating flow to the radiator, the stat has a spring loaded disc that covers a bypass port down in the pump housing.

If that bypass port is open, you get symptoms like a partially blocked radiator.

 

New OEM thermostat,

 

Not a good way to hook up that fan.. Just so you know.

Sounds like a thermostat.
