High-pressure die-cast aluminum alloy with corrosion-resistant coating, ensuring dimensional stability up to 130°C.
Integrated O-ring groove and flat mating surface guarantee zero coolant leakage, even under 2.5 bar system pressure.
OE-grade mounting points and hose connections match Howo/Sitrak engines (WD615, D12, MC11, MC13) without modification.
Tested for 500+ thermal shock cycles from -40°C to +140°C, preventing warpage and stress cracks.
Manufactured under IATF 16949 standards, delivering dealership-level quality at a fraction of the cost.
Stable coolant flow prevents hot spots and cavitation, reducing cylinder head gasket and water pump wear.
Used by major logistics operators in Europe, Southeast Asia, and South America; average service life exceeds 800,000 km.
Bolt-on replacement with clear torque specifications; no special tools required, reducing downtime by 40%.

Direct replacement for 2012–2025 models with MC11/MC13 engines; matches original mounting bracket and coolant hose routing.
Fits both 6×4 and 8×4 chassis; compatible with high-power auxiliary cooling systems and retarder circuits.
Used in concrete mixers, dump trucks, and fire engines; consistent performance under PTO-driven auxiliary loads.
Extensively validated in hot desert (50°C) and cold plateau (-30°C) conditions, ensuring reliable thermostat response.
Every unit undergoes 100% leakage inspection at 2.2 MPa air pressure; leakage rate < 0.5 cc/min.
CMM measurement of all critical mating surfaces, ensuring flatness ≤0.05 mm and hole position tolerance ±0.1 mm.
Cyclic test from -40°C to 140°C for 300 cycles; no cracks, deformation, or coating peeling.
Each batch comes with mill test reports, chemical composition analysis, and mechanical property certificates.
The VG1246060023 thermostat housing is backward-compatible with earlier Howo/Sitrak models, but always verify your engine serial number to ensure perfect fitment. For mixed fleets, keep a small stock of this housing to minimize unplanned downtime.
220 L/min @ 2800 rpm (with 88°C thermostat), reducing engine heat-up time by 18% compared to generic housings.
Thermostat opening stroke 8.2 mm ±0.3 mm, ensuring rapid temperature stabilization within 3 minutes after cold start.
12% lighter than OEM cast iron versions, contributing to overall vehicle weight savings and improved fuel economy.
Backed by a 12-month / 150,000 km warranty against manufacturing defects, with technical support from our engineering team.
Final Verdict: The VG1246060023 thermostat housing is not merely a spare part—it is a long-term investment in your powertrain’s thermal health. Its precision engineering, rigorous testing, and direct compatibility with Howo/Sitrak trucks make it the smart choice for fleet managers and owner-operators who prioritize uptime and performance. Combine it with a high-quality thermostat and coolant, and you will experience consistent engine temperatures, reduced emissions, and lower operating costs over the entire service interval.
