NOOYEESMO Coolant Reservoir Tank Fits 2014-2019 Silverado 1500/Suburban - Direct-Fit PP Expansion Tank, OEM-Equivalent

NOOYEESMO coolant reservoir tank is a direct-fit replacement expansion tank designed to restore proper coolant overflow storage and pressure management for select Chevrolet and GMC trucks and SUVs.

This replacement coolant overflow (expansion) tank is crafted from heat- and vibration-resistant polypropylene to match OEM dimensions and function. It stores excess coolant when your engine runs hot and returns fluid to the radiator as the system cools, helping maintain the correct coolant level and reduce air intrusion. The tank is manufactured to meet or exceed original equipment standards and is compatible with a range of Chevrolet and GMC models from model years 2014 through 2020.

How does it perform compared with the original tank?

The NOOYEESMO reservoir is engineered to match OEM shape and operation while offering durable PP plastic construction that resists heat and vibration. It functions as an overflow reservoir—capturing expanding coolant under pressure and returning it to the radiator during cooldown—so system balance is preserved.

• OEM-equivalent shape and mounting for straightforward installation
• High-temperature polypropylene resists cracking and warping
• Designed to handle expansion, pressure changes, and return flow reliably

What parts or numbers does this replace?

If your vehicle’s original tank shows cracking, leaks, or degraded plastic, this replacement corresponds to multiple factory part numbers for easier cross-reference. Use these numbers to verify compatibility with your service manual or parts lookup before purchase.

• Replaces part numbers: 22856231, 603-973, 84368362, 13502354
• Also cross-referenced to additional IDs used by dealers and aftermarket catalogs
• Keep the old tank available during installation to confirm hose and bracket alignment

What should I expect during installation and maintenance?

Installation is typically straightforward for anyone comfortable with basic under-hood work: drain the overflow fluid as needed, unbolt the old tank, transfer any sensors or fittings, and mount the new tank in place. Periodic inspection for cracks, loose hoses, or discoloration helps prevent leaks and coolant loss.

• Simple bolt-on replacement using OEM mounting points and hose connections
• Transfer existing cap, sensors, or fittings when required for exact fit
• Inspect hoses and clamps and refill with the manufacturer-recommended coolant
