FLEECE FPE-CLNTBYPS-CUMMINS-0607 CUMMINS COOLANT BYPASS KIT 2006-2007 AUTO TRANS

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+ 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. The '03-'07 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger.

The heat exchanger is not a fluid cooler; it was 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.

All ‘07-‘13 6.7 trucks, both automatic and manual equipped transmissions, do not have a transmission fluid heat exchanger.

  The Fleece Coolant Bypass Kit (FPE-CLNTBYPS-CUMMINS-0607) for 2006-2007 Cummins models is engineered to elevate the performance and durability of your vehicle's cooling system. Designed specifically for the 5.9L and 6.7L Cummins engines, this kit addresses the critical issue of coolant flow to the rear cylinders, which often suffer from elevated temperatures. Such imbalances can lead to excessive pressure within the cooling system, potentially causing serious damage such as freeze plug blowouts.
  
  With the added secondary thermostat featured in this kit, a proactive approach to temperature regulation is achieved. Unlike competing products that rely on pressure thresholds, this thermostat activates based on actual coolant temperature, effectively maintaining balanced and optimal temperatures across all cylinders. This innovative design lowers coolant temperatures at the rear cylinders, reducing the risk of catastrophic failures and enhancing overall engine reliability.
  
  Installation is straightforward, thanks to a complete kit that includes a braided hose and AN O-ring fittings, ensuring a leak-free fitment within the engine’s compartment. For models from 2003 and beyond, the kit also incorporates practical billet hose brackets for added durability and functionality.
  
  The Fleece Coolant Bypass is crucial for anyone seeking longevity from their Cummins platform, especially with the 5.9L automatic transmission version, which eliminates the factory transmission fluid heat exchanger. This component, designed primarily for cold climates, is unnecessary in warmer conditions or when high horsepower is desired.
  
  Fitment is precise for 2006-2007 Dodge Ram 2500 and 3500 models, accommodating various trims such as Laramie, SLT, Sport, and more. Elevate your vehicle's cooling efficiency and ensure its lasting performance with the Fleece Coolant Bypass Kit.
