2007.5-2018 Dodge Ram Cummins 6.7L (Manual & Automatic Transmissions)

Description:
【High Performance】Specially designed to help lower coolant temperature at the rear cylinders, preventing damaging coolant pressure build-up and ensuring consistent temperatures across all cylinders.
【Easy Installation】Complete kit comes with high-quality AN O-ring fittings and AN hose connections with braided hose to ensure a leak-free installation. Professional installation is highly recommended, No instruction is included.
【Must Kit】One of the biggest issues on the 24 valves is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. Can effectively help eliminate the possibility of scored rear cylinders and blown freeze plugs for your 6.7 Cummins with this Coolant Bypass Kit, improves the reliability and longevity for Cummins platform.

Benefits:

• Lowers coolant temperature at the rear cylinders
• Ensures consistent temperatures across all cylinders
• Prevents damaging coolant pressure build-up
• Complete kit comes with a braided hose and AN O-ring fittings to ensure a leak-free installation

One of the biggest issues on the 5.9L/6.7L Cummins is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. The SPELAB Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.

The rear cylinders on the 5.9L/6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block, and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Our coolant bypass kit adds a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before the pressure becomes an issue by ensuring consistent temperatures across all six cylinders.
