GMC Sierra 3500 Coolant Tank Kit - Wehrli - OEM Placement, Powder Coated, Sight Glass - Sparkle Copper - 01-07. Replace the aging factory reservoir with a fabricated aluminum tank that fits the stock location and adds an easy-to-read sight glass.
Built by Wehrli Custom Fab for 2001-2007 GM 6.6L Duramax LB7/LLY/LBZ trucks, this tank uses OEM mounting points for a clean, direct install on stock vehicles. The custom single-stage Sparkle Copper powder coat looks sharp and resists corrosion, while the integrated sight glass simplifies coolant checks. Kit includes a black anodized CNC-machined billet cap, mounting hardware, overflow hose, and low coolant level sensor. Installs with basic hand tools and replaces GM part numbers 15808714, 15290795, and 19353729.
