Coolant Bypass Kit for 2013-2018 Ram with 6.7L Cummins

Coolant Bypass Kit for 2013-2018 Ram with 6.7 L Cummins

The rear cylinders of the 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 leads to a malfunction. This coolant 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.

• Reduces the coolant temperature at the rear cylinders
• Ensures consistent temperatures in all cylinders
• Prevents harmful build-up of refrigerant pressure
• The complete set comes with a braided hose and O-ring couplings to connect a --ensure leak-free installation.

The set includes:

• Thermostat housing for bypass of rear coolant
• Thermostat housing for coolant bypass front
• New EGR crossover tube gaskets
• Black braided nylon refrigerant bypass hose with AN fittings
• Mounting hardware
