The valve at the bottom of the radiator is actuated by vacuum and is controlled electronically by a solenoid valve attached to the firewall. It is actually opened when the pump starts to allow air to flow to the exhaust manifold. If the valve is closed, air will escape at the hose connection to the valve and through the valve itself while the pump is running. It seems as though your valve isn't opening when it is supposed to. Follow the hose from the valve to the solenoid valve on the firewall. Make sure the electric connection there is clean and secure. Also make sure you are getting vacuum to both the solenoid valve and the vacuum controled valve and check to see if either of them are stuck closed. The pump will run at much higher speeds when the valve is closed and is consequently much louder.
