GMC Sierra 2500 HD Coolant Tank Kit - Wehrli - OEM Placement - Semi-Gloss Black - 07-10. A durable fabricated aluminum reservoir that replaces the factory plastic tank while retaining OEM fit and connections.

Designed for 2007.5-2010 GMC Sierra 2500/3500 HD with the 6.6L Duramax LMM, this Wehrli Custom Fab coolant tank mounts in the stock location and tidies up the engine bay. The semi-gloss black powder-coated aluminum body resists heat and cracking, while the integrated sight glass makes level checks quick. The kit includes a black anodized CNC-machined billet cap, mounting hardware, overflow hose, and low-coolant level sensor. It uses factory mounting points, installs with basic hand tools, and replaces GM part number 15120611. Made in the USA.
