FITMENT

• 2009–2019 6.7L Ram Cummins 2500 / 3500 Turbo Diesel (Pickup).
• 2009–2019 6.7L Ram Cummins 3500 / 4500 / 5500 Turbo Diesel (Cab & Chassis).

DESCRIPTION

Product Overview

• The 6.7L Cummins Turbo Diesel is built for heavy-duty work, but demanding towing and high-load operation can increase thermal stress throughout the cooling system.
  
• A coolant bypass hose helps improve coolant circulation by providing an additional flow path to reduce heat concentration in the rear area of the engine, where cylinders #5 and #6 typically experience higher thermal loads.
• By promoting more consistent coolant flow, this upgrade helps reduce thermal stress, improve cooling system reliability, and support long-term durability during towing and demanding applications.

Key Features

• Heavy-Duty Construction: Built with reinforced silicone hoses and CNC-machined aluminum fittings for long-lasting durability and corrosion resistance.
  
• Leak-Resistant Design: High-quality connections and upgraded fittings help provide reliable coolant system performance.
• Rear Cylinder Cooling Support: Improves coolant circulation around the rear cylinders (#5 & #6), helping reduce heat concentration and maintain more consistent cylinder head temperatures.
• Improved Cooling System Balance: Provides an additional coolant flow path to reduce thermal stress during heavy towing, hauling, and high-load operation.

FAQ

Q: Why does my 6.7L Cummins need a coolant bypass hose barb adapter?

A: Heat cycles and vibration cause factory coolant connections to wear and leak over time. This upgraded billet adapter provides a stronger, leak-free connection for long-term durability.

Q: What problem does this coolant bypass adapter solve?

A: When used as part of a coolant bypass system, this adapter helps support improved coolant circulation near the rear area of the engine, where cylinders #5 and #6 experience higher thermal loads during heavy-duty operation.

Q: Can I install this with my EGR delete kit?

A: Yes. This adapter can be used with many 6.7L Cummins EGR delete and coolant reroute configurations to provide a secure coolant connection.

Q: Will this work with my stock cooling system?

A: Yes. This adapter can be used with compatible factory cooling systems and aftermarket cooling upgrades. Always confirm fitment before installation.
