Abstract
The present teachings provide for a flow restrictor for a coolant line of an internal combustion engine coolant system. The flow restrictor can include a restrictor element and a biasing member. The restrictor element can include a restrictor plate and a tab non-rotatably coupled at an angle. The biasing member can rotationally bias the restricting element to a first position where the restricting plate is substantially parallel to the flow of fluid. The tab can be configured to create a torque on the restricting element to overcome the biasing member and rotate the restricting plate to block a portion of the fluid flow path when the flow exceeds a predetermined flow rate.
