Introduction

SINOTRUCK Expansion Tank WG9719530260 is a high‑quality, direct‑fit coolant reservoir designed for SINOTRUCK HOWO heavy‑duty trucks. As a key part of the engine cooling system, it accommodates coolant expansion and contraction, maintains stable system pressure, and removes air from the circuit—effectively preventing engine overheating and ensuring consistent cooling performance under heavy‑load, high‑temperature, or harsh working conditions. Built to OEM specifications with premium heat‑resistant plastic, it delivers reliable sealing, strong vibration resistance, and a long service life for heavy‑duty applications.
