The Square Root Fabrication L5P Duramax Turbo Coolant Fitting is a much needed prevention item.
As these L5P's age, and get more heat cycles through them, things tend to break down, and a factory part that has shown to have failures, is the factory coolant tube off the left hand side of the turbocharger. This line ends up breaking near a welded area towards the bolted flange (see below).
When this line ruptures/cracks, it will leave you stranded and you'll be forced to tow the truck, or search around for a dealership who has a replacement line for a premium and fix it on the side of the road.
Avoid future issues on your modified L5P Duramax with this Billet Aluminum Replacement.
