This question came up more than 50 years ago in the age of Flathead (wrought 
iron engine) powered dirt-track  racing  in stock cars and sprinters with 
heating problems.  One cure was a washer restrictor to slow down (?) the 
flow. Everybody thought that was the reason, and it worked.  Later we found 
that the stock water pumps were cavitating (creating bubbles) from being 
wound so tight and the washer increased the pressure on the pump and reduced 
the tendency to cavitate.  The bubbles reduced the contact of water to 
wrought iron and caused real hot spots. Other cures included modifications 
to the pump to reduce cavitation.

Today's water pumps  surely must be turning RPM's beyond their design RPM 
and restrictors may be  doing the same thing as they were doing 50 years 
ago- reducing cavitation.
