About This Product
This is a direct-from-GM, brand-new coolant recovery tank designed for 2011-2012 Chevy Silverado and GMC Sierra trucks with the Duramax diesel engine.
It’s the genuine OEM part, number 22866587, so you know it’s going to fit right and last.
If your current tank is cracked, leaking, or just ugly, this swap is straightforward—it mounts right in, and you’re back on the road.
It also crosses with part numbers 22769155, 22810003, and 25869265, plus aftermarket numbers like 390328 and 603-008.
Comes with a 2-year manufacturer warranty, so it’s backed.
This is just the tank (part #8 on the diagram if you're looking at the schematics), not the whole assembly.
Keep your diesel's cooling system in top shape with this fresh OEM replacement.
