Overview

Meet the YzusGomumu Coolant Expansion Reservoir Tank with Cap, a sturdy replacement designed for GM trucks and SUVs from 2015 through 2020. It is built to integrate with the factory cooling system, helping to keep engine temperatures balanced across daily commutes, road trips, and demanding driving scenarios.

What it does

Engine cooling is a key part of dependable performance. This expansion tank works with the cooling loop to help maintain steady temperature and containment in the face of heat buildup. While not a guarantee, you may notice more stable operation in challenging conditions, and it can reduce stress on the surrounding components by providing a reliable vessel for coolant when the system heats up.

Key benefits

  • Helps keep the cooling system balanced in varying conditions, potentially reducing overheating-induced stalling or stress on components.
  • Durable construction using high-quality materials to withstand temperature swings and pressure changes within the cooling loop.
  • OE-number references: 22856231, 84368362, GM3014134, 603-973, 3014134; verify compatibility with your vehicle before purchasing.
  • Timely replacement supports seals and containment, contributing to safer operation of the cooling system.
  • Cap included for convenient retrofit and proper cap-and-tank pairing.

Compatibility highlights

This tank is designed to fit a broad range of GM models from 2014 through 2020, with engines commonly found in these vehicles.

  • Cadillac Escalade and Escalade ESV (2015–2020)
  • Chevrolet Silverado 1500, Suburban, Tahoe (2014–2019)
  • GMC Sierra 1500, Yukon/Yukon XL (2014–2019/2020)

Durability you can trust

The reservoir is built to endure daily driving demands and temperature fluctuations, helping maintain coolant containment and system tightness over time.
