If you’ve performed a race or off-road-only conversion on your 6.7-liter Cummins, you know about the messy bundle of unsupported coolant hoses left behind when the EGR cooler is removed. That setup is a ticking time bomb for coolant leaks and gets in the way of future upgrades. Pusher Intakes just shared how to use its Coolant Reroute Kit, a kit that eliminates those problems permanently and cleans up the engine bay.
The Problem With The Factory Setup
After an off-road or race conversion, the factory coolant riser tube loses its main support structure. This allows the entire assembly to vibrate excessively whenever the engine is running. As the Pusher Intakes video points out, this constant vibration is notorious for causing the built-in flex joint in the factory tube to fail, leading to coolant leaks all over the engine. The bulky factory tube also occupies valuable real estate, making it difficult to install popular upgrades like a second-gen style turbo swap or a high-mount compound turbo system.
The Pusher Coolant Reroute Solution
The installation process focuses on modifying the factory riser tube to accept a new billet adapter, and the video provides some critical tips. The host strongly warns against using a pipe cutter to shorten the factory tube, as it can deform the pipe and prevent the new O-ring from sealing properly. He recommends a bandsaw or cutoff wheel for a clean, square cut. The host calls the most important step deburring, where the inside of the cut tube must be chamfered into a funnel shape.
Reassembly And Final Touches
Pusher Intake’s kit is a complete solution that addresses all the loose ends left after an off-road or race conversion. The kit includes a plug to block off the old EGR coolant port in the cylinder head. It also provides a new, sturdy stainless steel bracket to properly secure the transmission dipstick tube to the side of the head. Another included bracket cleanly relocates the drive pressure sensor, neatly tying up all the components that were left hanging after the EGR cooler was removed.
A Cleaner, More Reliable Engine Bay
Once installed, the benefits of the kit are immediately obvious. The new design completely eliminates the vibration-prone factory parts, providing a much more reliable, leak-free cooling system. It also opens up a huge amount of space in the engine bay, making future turbo upgrades much easier. For any 6.7-liter Cummins owner with an off-road or race setup, the Pusher Coolant Reroute Kit is a good option that provides peace of mind, more room to work, and a much cleaner look.
