TruckTok 2013-2018 6.7L Ram Cummins Coolant Bypass & EGR Cooler Throttle Delete Kit

FITMENT

• 2013–2018 6.7L Dodge Ram Cummins 2500 & 3500 Pickup Turbo Diesel.
  
• Note: Does NOT fit Cab & Chassis (3500 / 4500 / 5500 C&C) models.

DESCRIPTION

Product Overview

• Factory 6.7L Cummins engines can experience EGR-related intake contamination and coolant leak issues from factory plastic coolant fittings. The OEM EGR system recirculates exhaust soot into the intake, contributing to carbon buildup, while repeated heat cycles can weaken plastic coolant connectors and cause leaks over time.
• The Cummins Package addresses these common failure points with an EGR cooler delete assembly and CNC-machined billet aluminum coolant hose barb adapter. This upgrade helps reduce soot contamination and provides a stronger, more reliable cooling system connection.

Key Features

• EGR Cooler & Valve Delete: Permanently removes the heavy OEM EGR cooler assembly, stopping hot soot recirculation and eliminating internal cooler leak risks.
  
• Billet Coolant Barb Leak Adapter: Replaces brittle, leak-prone OEM plastic coolant adapters with a heavy-duty, billet aluminum hose barb adapter that resists high heat, pressure, and warping.
• High-Flow Throttle Valve Delete Tube: Replaces the restrictive inline butterfly valve with a smooth, straight-through delete pipe to maximize clean, pressurized intake CFM.
• Reduces Engine Bay & Intake Temps: Eliminating EGR gas circulation lowers pre-deletion intake temperatures and reduces overall under-hood engine bay heat.

FAQ

Q: What specific problem does the included Coolant Bypass Hose Barb Adapter Kit solve?

A: The factory coolant riser connectors use plastic fittings that can weaken and crack from repeated heat cycles. The CNC billet aluminum barb adapter replaces this weak point with a stronger, more durable connection to help prevent coolant leaks.

Q: Does this kit allow faster coolant circulation than the stock EGR setup?

A: The EGR cooler bypass simplifies the factory coolant routing and uses high-flow silicone lines with a billet adapter to help maintain smooth coolant circulation and consistent operating temperatures.

Q: Where is the best location on the exhaust block-off plate to install my EGT probe?

A: The included exhaust block-off plate features a pre-tapped 1/8" NPT port positioned directly over the rear exhaust manifold passage. This location gives your gauge or tuner the most accurate, real-time pre-turbo EGT readings without requiring you to drill into the cast-iron manifold.

Q: Can I install this kit if I am keeping my stock exhaust, or do I need a 4" DPF Race Pipe?

A: This kit focuses on engine-side upgrades, including EGR delete, throttle valve delete, and coolant system improvements. A compatible ECM tune is required after EGR removal. A 4" or 5" DPF delete pipe is recommended to further improve exhaust flow and overall performance.
