GMC Sierra 2500 Coolant Tank Kit - Wehrli - OEM Placement - Sparkle Copper - `07-`10. Replace the brittle plastic reservoir on your 2007.5–2010 Duramax LMM with a fabricated aluminum tank that mounts in the factory spot and features a Sparkle Copper finish.

From Wehrli Custom Fab (WCFab), it bolts to OEM points for an easy install with basic hand tools on stock trucks. The tank adds a sight glass for quick checks and arrives with a black anodized CNC-machined billet cap, overflow hose, mounting hardware, and a low-coolant sensor. It’s powder coated for durability and directly replaces GM 15120611.
