Overview

NOOYEESMO 603-054 coolant reservoir tank with cap offers a direct-fit replacement designed for GM SUVs and trucks from 2007 through 2014, with broad compatibility across Silverado, Sierra, Suburban, Tahoe, Yukon, Escalade families and more. Constructed from high-quality PP plastic, this reservoir emphasizes durability, resisting the stresses of hot engine compartments and the rhythmic vibrations of daily driving.

In normal operation, coolant expands as the engine warms and the reservoir provides a secure space for the extra fluid. When the engine cools, the coolant is drawn back into the radiator, helping maintain steady operating conditions and reducing pressure fluctuations within the cooling system. The OEM-inspired design mirrors factory contours to preserve a clean, integrated look under the hood.

Key benefits

  • Durable PP plastic resists high temperatures and vibration for long service life.
  • Supports controlled coolant expansion and return to the radiator to help maintain stable conditions.
  • OEM-like dimensions offer a direct-fit replacement with minimal modification.
  • Clear reservoir body aids level checks and quick diagnostics of coolant flow.
  • Versatile compatibility with multiple GM models and corresponding part numbers for flexible use.

What you get

  • 603-054 coolant reservoir tank with cap
  • OE-style fitment that aligns with factory hoses and clamps
  • Part-number compatibility reference including 603-054 and related numbers
