L5P Turbo Coolant Hose Upgrade (2020-2026)

Say goodbye to cracking and messy coolant leaks with this Turbo Coolant Hose Upgrade for your 2020–2026 Duramax L5P.

The original factory coolant line is known for wearing out, cracking under heat stress, and leaking over time. This heavy-duty upgrade fixes that headache for good. Built with solid billet aluminum fittings and sealed using high-temp O-rings, it’s built to withstand the extreme under-hood temperatures your turbo throws at it.

We utilize compression clamps to give you a snug, trouble-free seal that installs easily and lasts.

What’s Included:

• Upgraded Turbo Coolant Fitting (Billet Aluminum)

• Coolant Hose

• Clamps
