Fleece Performance 07.5-16 6.7L Cummins Coolant Bypass SS

Fleece Performance 07.5-16 6.7 L Cummins Coolant bypass SS

The rear cylinders of the 5.9/6.7 L Cummins suffer from a lack of coolant flow and therefore experience the highest coolant temperatures. This can lead to excessive pressure in the cooling system, especially at the back of the block, and blow through freezer plugs from the outside or the smaller diameter plugs under the valve cover, which can lead to a malfunction.

The refrigerant bypass kit adds a secondary thermostat, which unlike other brands, operates based on temperature rather than excessive pressure. This solves the problem before pressure becomes a problem by ensuring consistent temperatures in all six cylinders.
