FLEECE FPE-CLNTBYPS-CUMMINS-0305 CUMMINS COOLANT BYPASS KIT 2003-2005 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.

  Enhance the performance and longevity of your 2003-2005 Cummins engine with the FLEECE FPE-CLNTBYPS-CUMMINS-0305 Coolant Bypass Kit. Specifically designed to tackle the common coolant flow issues faced by the rear cylinders of 5.9 and 6.7L Cummins engines, this premium bypass kit ensures increased coolant flow and decreased temperatures, which are critical for optimal engine function.
  
  The rear cylinders are notorious for inadequate coolant circulation, leading to dangerously elevated temperatures that can result in excessive pressure within the cooling system. This pressure can cause costly failures, such as blown freeze plugs or damage under the valve cover. The innovative design of our coolant bypass kit incorporates a secondary thermostat, activating based on temperature instead of pressure. This proactive approach helps maintain consistent coolant temperatures across all cylinders, effectively preventing overheating and associated damage.
  
  Key features of the Fleece Coolant Bypass Kit include a complete installation package with braided hoses and AN O-ring fittings, ensuring a leak-free and secure fit. Additionally, the kit comes with billet hose brackets for models manufactured in 2003 and later, further enhancing installation reliability.
  
  The Fleece Coolant Bypass is not just an upgrade; it is an essential enhancement for maintaining the Cummins engine's reliability. By eliminating the factory transmission fluid heat exchanger, which was primarily designed for cold-weather use, this kit optimizes performance in warmer climates and high horsepower applications.
  
  Fitment is precise, catering to various models of the 2003-2005 Dodge Ram 2500 and 3500 series. Prioritize your engine’s health with the Fleece Coolant Bypass Kit, the comprehensive solution to sustain your Cummins engine's performance and durability.
