FLEECE FPE-CLNTBYPS-CUMMINS-12V 12V COOLANT BYPASS KIT 1994-1998

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.

DETAILED FITMENT:

• 1994-1998 Dodge Ram 2500
• 1994-1998 Dodge Ram 3500

  Enhance the performance and reliability of your 1994-1998 Dodge Ram 2500 or 3500 with the Fleece FPE-CLNTBYPS-CUMMINS-12V 12V Coolant Bypass Kit. This innovative solution is specifically designed to tackle a common issue faced by 5.9 and 6.7L Cummins engines: inadequate coolant flow to the rear cylinders. Such flow deficiencies can lead to dangerously high temperatures, creating excessive pressure within the cooling system and risking catastrophic damage, including freeze plug blowouts.
  
  With the Fleece Coolant Bypass Kit, you benefit from improved coolant circulation that significantly lowers temperatures at the rear cylinders. This kit integrates a secondary thermostat that intelligently regulates temperature, ensuring uniform cooling across all cylinders rather than merely reacting to pressure spikes. By preemptively addressing potential overheating, this kit promotes optimal engine performance and longevity.
  
  The complete package includes all necessary components: a high-quality braided hose and AN O-ring fittings that guarantee a leak-free installation. For models manufactured from 2003 and beyond, additional billet hose brackets are part of the offering to further enhance installation precision.
  
  Addressing coolant flow issues is paramount for the reliability of your Cummins engine. The Fleece Coolant Bypass not only prevents excessive pressure build-up but also eliminates the factory transmission fluid heat exchanger for ‘03-‘07 5.9L automatic transmissions, providing better performance in warmer climates or high-horsepower setups.
  
  Unlock the full potential of your Cummins-powered truck with a key enhancement that ensures a balanced temperature distribution. Trust in the Fleece Coolant Bypass Kit to safeguard your engine from overheating, ensuring it runs smoother and lasts longer on the road.
