GMC Sierra 3500 HD Coolant Tank Kit - Wehrli - OEM Placement, Bengal Silver, 07–10: a direct-fit fabricated aluminum reservoir that replaces the brittle factory plastic tank and adds a clear sight glass.

Built for 2007.5–2010 GM 6.6L Duramax LMM trucks, this Wehrli Custom Fab tank mounts in the OEM spot using factory points—no extra mods. The Bengal Silver powder coat keeps things tidy, and the sight glass makes checks quick. Kit includes a black anodized CNC billet cap, mounting hardware, overflow hose, and low-coolant sensor. Installs with basic tools and replaces GM part 15120611. Made in the USA.
