While you may have heard of a Coolant Bypass Kit, you may be uncertain what it does and why you'd want to outfit your Cummins with one. In short, the factory routing of coolant circulation in your engine causes the rear cylinders to run at a substantially hotter temperature compared to the front cylinders, which can cause catastrphic failure of blow outs of the freeze plugs. By adding a coolant bypass kit, coolant is rerouted to give properly distributed circulation of the coolant to all six cylinders, resulting in an overall cooler running engine. Fleece Performance Engineering manufactures a wide range of vehicle specific Coolant Bypass Kits to aid in extending the life of your engine.
