TruckTok 2009-2019 6.7L RAM Cummins Coolant Hose Barb Adapter Leaking Repair Kit

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 should I install a coolant bypass kit on my 6.7L Cummins?

A: The factory cooling system works well for daily driving, but heavy towing can increase heat concentration at the rear of the engine. This coolant bypass kit improves circulation to maintain more consistent temperatures and reduce thermal stress.

Q: What problem does this coolant bypass hose solve?

A: This kit provides an additional coolant flow path to improve circulation in the engine cooling system. It helps reduce heat buildup in high-stress areas and supports more stable cooling performance during towing, hauling, and demanding driving conditions.

Q: Does this kit help cool cylinders #5 and #6?

A: Yes. The bypass design improves coolant circulation near the rear cylinders, helping reduce heat concentration and maintain more balanced cylinder head temperatures.

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

A: Yes. This coolant bypass kit works with many EGR delete configurations and can be installed as a supporting cooling system upgrade after removing the factory EGR cooler.
