Coolant Reroute Kit for 6.7 Cummins 2013-2018 | Coolant Line Relocation and Riser Replacement
The Diesel Power Source® Coolant Reroute Kit for 2013-2018 Ram 2500 and 3500 trucks with the 6.7L Cummins engine replaces the factory plastic coolant riser, stand-up pipe, and associated coolant lines with steel-braided lines, silicone hose, and machined steel fittings. This kit eliminates the failure-prone factory plastic coolant components at the top-rear of the engine and provides a clean, organized coolant line routing for trucks running aftermarket turbo configurations.
This kit relocates and replaces the coolant tank, reroutes coolant lines for proper clearance with compound turbo kits, 2nd gen swap kits, and other aftermarket turbo setups, and removes the factory coolant riser and stand-up pipe that are no longer needed once the EGR system has been removed. It is included with DPS compound turbo kits for 2013-2018 trucks and is also available separately for trucks with other aftermarket turbo configurations.
Diesel Power Source® does not provide emissions delete components. This kit is designed for trucks that have already had EGR removal completed.
Why the Factory Coolant Riser Fails
The 2013-2018 6.7 Cummins uses a plastic coolant riser and stand-up pipe at the top-rear of the engine that routes coolant through the EGR system. These factory plastic components are exposed to extreme engine heat and under-hood temperatures, and they become brittle and crack over time. When they fail, coolant leaks onto the exhaust manifold and turbo, creating a mess in the engine bay and potentially causing overheating if not caught quickly.
Even on trucks that have not had the EGR system removed, the factory plastic coolant pieces are a known failure point. This kit replaces those plastic components with steel-braided lines and machined steel fittings that handle the heat and pressure without degrading. On trucks where the EGR system has been removed, this kit also cleans up the leftover coolant lines and components that are no longer serving a purpose, resulting in a significantly cleaner and more organized engine bay.

Frequently Asked Questions
And here is the body that is a little longer
p>The plastic coolant riser pipe at the top rear of the engine is the most common cooling failure on 2013–2018 6.7L Cummins trucks. This OEM plastic component cracks from heat cycling, causing coolant loss and overheating. It is a known issue that has affected a significant number of late 4th gen trucks, particularly those used for heavy towing or running in modified form where under-hood temperatures are elevated. The Diesel Power Source® coolant reroute kit eliminates this component entirely and replaces it with steel braided and silicone hose and an aluminum coolant tank for deleted trucks.Yes. This coolant reroute kit is included with DPS compound turbo kits for 2013-2018 6.7 Cummins trucks. If you are purchasing a DPS compound kit for these model years, you do not need to buy this separately. This listing is for trucks with other aftermarket turbo configurations that need the coolant reroute as a standalone purchase.
The factory 2013-2018 6.7 Cummins uses a plastic coolant riser and stand-up pipe at the top-rear of the engine. These plastic components are exposed to extreme heat and become brittle over time, leading to cracks and coolant leaks. This kit replaces all factory plastic coolant components with steel-braided lines and machined steel fittings. It also reroutes the coolant lines to clear aftermarket turbo systems and relocates the coolant tank for proper clearance with compound turbo kits and 2nd gen swap configurations.
The Diesel Power Source® 6.7 Cummins coolant reroute kit eliminates the failure-prone plastic coolant riser pipe on 2013–2018 trucks and reroutes the coolant circuit through steel braided hose, silicone hose, machined fittings, and a new aluminum coolant tank. It also relocates the coolant tank to clear space for compound turbo kits and 3rd gen swap installations. This kit is designed for trucks that have had the EGR system deleted and is not compatible with the stock EGR configuration.
On 2007.5–2012 trucks the compound kit installation typically does not require coolant system changes beyond ensuring the turbo coolant lines are in good condition. On 2013–2018 trucks where the compound kit requires moving or removing components in the area where the plastic coolant riser is located, the coolant reroute kit is effectively required as part of the compound installation — it clears the space needed for the compound turbo system while simultaneously eliminating the failure-prone stock components. Diesel Power Source® recommends addressing the coolant riser proactively on any 2013–2018 truck being modified.
Cummins recommends a coolant flush interval of approximately 150,000 miles or 5 years for the OAT coolant used in the 6.7L, whichever comes first. On trucks used for heavy towing where the cooling system operates near capacity regularly, erring toward the shorter end of that interval is reasonable. Using the correct OAT-specification coolant at the correct concentration — typically 50/50 with distilled water — is important for corrosion protection in the aluminum components of the cooling system. Do not mix coolant types or use tap water for top-offs.
EGR cooler failure on the 6.7L Cummins typically presents as white smoke from the exhaust during warmup or under load, unexplained coolant loss without visible external leaks, a sweet smell from the exhaust, or in more advanced cases, coolant contamination of the oil. A combustion gas test of the coolant — which detects exhaust gases dissolved in the coolant — is the most reliable early-stage diagnostic. Addressing EGR cooler failure promptly prevents the more serious damage that comes from extended coolant contamination of the engine's oil system.
For a direct-fit VGT replacement or a Turbonator® VGT upgrade on a 6.7L, the factory coolant lines can typically be reused if they are in good condition. When upgrading to a 3rd gen swap kit or compound system on a 2013–2018 truck, the coolant reroute kit is required to clear the space needed for the new turbo positioning and to replace the factory plastic components that are incompatible with the new layout. On any turbo upgrade, inspecting the existing turbo coolant lines and replacing them if they show signs of age or degradation is a worthwhile step that protects the new turbo investment.
