The heater bypass blockoff replaces a thermostat in an OE LS water pump. This, in conjunction with properly managed heater core lines, will prioritize cool water suction from the radiator and coolant flow back to the radiator. Cooled water from the radiator will keep your engine temperature exactly where you want it!
Gasket not included but can be added!

This little gadget should be on the list for every LS car that isn't running heat. Absolute game changer for cooling, especially in turbo street car applications that tend to have excess engine bay heat. Much better operating temps, less dependence on the fan, and makes bleeding air from the system INCREDIBLY easy
