FLEECE FPE-CLNTBYPS-CUMMINS-12V-SS CUMMINS COOLANT BYPASS KIT 12V 94-98 WITH STAINLESS STEEL BRAIDED LINE

Increased Coolant Flow, Decreased Coolant Temperatures. The rear cylinders on the 5.9/6.7L 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 pressure becomes an issue by ensuring consistent temperatures across all six cylinders.

Benefits:

• Lowers coolant temperature at the rear cylinders
• Ensures consistent temperatures across all cylinders
• Prevents damaging coolant pressure build up
• Complete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation.
• Kits for MY 2003 and up include billet hose brackets.

Why do I need a Fleece Coolant Bypass?
One of the biggest issues on the 5.9/6.7L 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 Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.
Application Notes:

• The 2003 - 2007 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is designed for use in cold climates to warm the transmission fluid with the engine coolant. It is not necessary for use in warm climates or high horsepower applications, nor does it detrimentally affect the trucks performance when removed.
• For model years 2007 - 2018 6.7L trucks, including both automatic and manual equipped transmissions, factory installed transmission fluid heat exchangers are uncommon. For customers with a 6.7L that has a heat exchanger, a heater tube can be purchased at your local Chrysler Dealership [PN:68048997AA] to complete the installation.

Revolutionize your cooling system with the FLEECE FPE-CLNTBYPS-CUMMINS-12V-SS Coolant Bypass Kit. Specifically designed for 5.9/6.7L Cummins engines from 1994-1998, this advanced kit ensures optimal coolant flow while maintaining ideal temperatures across all cylinders.

The Fleece Coolant Bypass Kit addresses a critical issue: the rear cylinders often suffer from insufficient coolant flow leading to excessive heat build-up. This issue can result in increased pressure in the cooling system, ultimately causing severe failures like blown freeze plugs. With our innovative secondary thermostat, you gain control over temperature instead of relying solely on pressure, preventing overheating before it becomes a problem.

• Significantly lowers coolant temperature at the rear cylinders
• Ensures uniform temperatures across all cylinders for optimal engine performance
• Prevents damaging coolant pressure build-up
• Complete installation kit includes stainless steel braided hose and AN O-ring fittings for a leak-free experience
• Models from MY 2003 and up come with robust billet hose brackets

The Fleece Coolant Bypass is a must-have enhancement for your Cummins engine, eliminating coolant flow challenges and enhancing overall reliability and longevity. Don’t compromise on performance; tackle potential failures before they arise with this essential coolant solution.
