Product Description
The Wehrli WCF100696‑GB Upper Coolant Pipe is a premium replacement for the weak, failure-prone OEM rubber hose on 2011–2016 LML Duramax diesel trucks. Built from durable mandrel-bent 6061 aluminum and powder-coated in a gloss black finish, it offers superior resistance to heat, pressure, and wear. Perfect for performance or show builds, this pipe not only boosts long-term reliability but also gives your engine bay a high-end appearance.
Designed specifically for use with the factory radiator, this kit includes heavy-duty silicone couplers and T-bolt clamps for a secure, leak-proof seal. Easy to install with no permanent modifications required--an ideal upgrade for any 6.6L LML Duramax enthusiast.
