Engine Coolant Reservoir Tank with Cap 22870828 - OEM Fit

In this review of the Engine Coolant Reservoir Tank with Cap 22870828, the bottom line is straightforward: this replacement tank is for owners of late-model Silverado, Sierra, Suburban, Tahoe, Yukon and Escalade vehicles who need a direct-fit, OEM-style overflow tank without fuss. The reviewer found it saves time on installation because it follows the original 603-054 design, and it is worth considering when the original reservoir is cracked or leaking. Overall it is a practical, cost-conscious repair part that prioritizes fit and durable construction over aftermarket extras.

Key Features

• OEM Design: The 603-054 pattern matches the original reservoir form and mounting points so replacement is straightforward and reduces installation time.
• Wide Fitment: Intended to replace part numbers including 22870828, 15833723 and 22797286, it covers Silverado 1500, Sierra 1500 and related GM models from 2007-2013.
• Durable Construction: Built from quality materials to resist everyday engine-bay heat and vibration for long-lasting service life.
• Complete with Cap: Supplied with a matching cap so the tank is ready to install and helps maintain the vehicle's proper coolant pressure and overflow control.
• Warranty Support: Backed by a 1-year warranty for added confidence and a clear channel for questions or replacements if issues arise.

Who It's For

This tank is best for DIY mechanics and professional technicians who need a direct OEM-style replacement for models listed in the fitment: Silverado 1500, Sierra 1500, Suburban, Tahoe, Yukon and Escalade from roughly 2007 to 2013. It suits people who want to restore the vehicle to factory-spec fitment without modifying mounts or hose connections.

Those who should look elsewhere include owners of vehicles outside the listed fitment or those wanting upgraded aftermarket reservoirs with added features such as sight-level windows, custom finishes, or integrated sensors; this part focuses on faithful replacement rather than cosmetic enhancement.
