Coolant reroute kit
The oring in the kit was too big in diameter to insert into existing pipe. Tried other size orings, but all leaked. Had to weld nipple to tube to make it work. After 3 drains and refill, finally it seals. Not to happy.

The Pusher 6.7L Cummins Coolant Reroute Kit is designed to improve coolant flow to the rear cylinders while simplifying the exhaust side of the engine. This straightforward setup reduces unnecessary clutter, enhances coolant distribution to the back of the cylinder head, and eliminates the factory coolant riser’s failure-prone flex joint — a common source of leaks.
It’s also an essential upgrade for aftermarket turbocharger configurations that typically require additional space beyond the factory layout.
Individual part overview:
This kit secures the following components while making room for other turbo configurations:

You guys should supply an o-ring for the bottom base of the riser. I thought everything was good to go. Few hours later coolant on the ground. I’ll have to go hunt for an o-ring of appropriate size and do some of this again tomorrow. Other than that, every was on point.
