Introduction

VG1500061203 Thermostat Housing is a core aluminum cooling system component exclusively matched for SINOTRUK HOWO heavy-duty truck engines. It acts as the fixed carrier for the thermostat and the connecting passage of engine coolant pipelines, stably locking the thermostat to guarantee accurate temperature regulation of circulating coolant. This housing standardizes the flow path of cooling liquid, solves common failures such as coolant leakage, housing cracking and loose thermostat installation caused by aging original parts, and keeps the engine running within a constant optimal working temperature. It is an essential replacement spare part for engine cooling system overhaul and daily maintenance of logistics and engineering heavy trucks.

Key Features

✅️Accurate OEM Matching Standard

Manufactured strictly following SINOTRUK OEM drawing standards with part number VG1500061203. Complete consistent mounting holes, pipe calibers and internal cavity size, perfectly compatible with all HOWO heavy trucks, dumpers and tractor units. Direct bolt-on installation without cutting or modification.

✅️High-Strength Cast Aluminum Material

Adopts precision die-cast aluminum alloy with uniform wall thickness, featuring high temperature resistance, pressure resistance and anti-cracking performance. It can withstand long-term high-temperature coolant impact and chassis vibration, no deformation or rupture under heavy-load driving.

✅️Excellent Sealing & Anti-Leakage Performance

Flat and smooth sealing flange surface fits tightly with gaskets, effectively isolating coolant seepage. Optimized internal flow channel design avoids turbulent flow and pressure surge, permanently maintaining stable coolant circulation without liquid loss.

✅️Stable Thermostat Positioning & Engine Protection

Precise internal limit structure firmly fixes the thermostat, preventing offset and jitter during vehicle operation. It ensures normal opening/closing of the thermostat, avoids overheating or low-temperature wear of engine cylinder, piston and other components, and extends engine service life.

✅️Cost-Effective Aftermarket Replacement

All products pass strict hydraulic pressure and high-temperature aging tests before delivery. Stable quality, low failure rate and competitive wholesale price, ideal for global truck parts dealers, repair shops and fleet maintenance bulk procurement.
