ACDelco Fuel Cooler, Duramax | 2001-2010

Keep your Duramax running reliably with this OE replacement fuel cooler designed specifically for 2001–2010 GM 6.6L Duramax trucks. The fuel cooler helps regulate fuel temperatures to maintain proper performance and longevity of the injection system.

Over time, the factory cooler can rust—especially around the connections—leading to fuel leaks that may cause drivability issues or potential safety concerns. Replacing a rusted or leaking cooler with this brand-new unit restores proper function and ensures a leak-free seal at the connections.

This OE cooler is a direct-fit replacement for a hassle-free installation and long-lasting durability.

• Fits 2001–2010 GM 6.6L Duramax
