Product Details

If you're swapping in a fixed vane turbocharger on your LB7, LLY, LBZ, or LMM Duramax, you'll need to address the coolant feed to the factory turbo. This plug from Wehrli Custom Fabrication is designed to seal off the upper coolant pipe where the thermostat used to be, making that swap cleaner and more straightforward.

This plug is machined from solid billet aluminum, giving it a strong and well-built feel. It's then finished with a black anodized coating, which not only looks good but also helps prevent corrosion. It's a simple part, but it's exactly what you need to properly complete that turbo upgrade without coolant leaks.
