Water Pump Bypass Hose

DESCRIPTION






A rubber water pump bypass hose is used between the intake manifold and water pump on all 3.9/5.2L and 5.9L engines.

OPERATION
When the thermostat is in the closed position the bypass hose allows the water pump to circulate the engine coolant through the cylinder block while at the same time preventing the coolant from flowing through the radiator, this allows the coolant to heat up quicker thus bring the engine to operating temperature faster.
