The VG1047060005 temperature regulator assembly is a genuine SINOTRUK HOWO component engineered to precisely control coolant flow, ensuring optimal engine operating temperature under all conditions. As a vital element of the trusted Sinotruk howo parts family, this regulator maintains the correct thermal balance, improving fuel efficiency and reducing emissions. Manufactured from corrosion‑resistant brass and stainless steel with a precision wax‑filled element, the VG1047060005 responds accurately to coolant temperature changes, opening and closing the bypass circuit to direct coolant through the radiator when needed. Its robust construction withstands the extreme thermal cycles and pressures of heavy‑duty diesel engines, making it essential for Howo trucks operating in mining, construction, and long‑haul applications.

The VG1047060005 regulator features a precision‑calibrated wax pellet that expands and contracts with temperature changes, providing reliable and hysteresis‑free actuation. The valve plate and frame are constructed from high‑grade brass and stainless steel, ensuring excellent corrosion resistance even with modern long‑life coolants. The assembly includes a robust jiggle pin to allow air to bleed during filling, preventing air locks. The opening temperature is factory‑set to 82°C (fully open at 95°C) to match the thermal requirements of Howo diesel engines.
Each VG1047060005 assembly undergoes rigorous testing, including thermal cycling and leak checks, to verify its performance across the entire temperature range. The valve lift meets OE specifications, ensuring adequate coolant flow to the radiator when open, and a tight seal when closed to promote fast engine warm‑up. This attention to detail guarantees that the temperature regulator assembly delivers consistent cooling system performance, reducing thermal stress on the engine and improving overall durability.

The VG1047060005 temperature regulator assembly is installed in the coolant outlet housing of Howo engines, controlling the flow between the engine bypass circuit and the radiator. During cold starts, the regulator remains closed, directing coolant through the bypass to allow rapid warm‑up. Once the coolant reaches the opening temperature, the valve gradually opens, sending coolant to the radiator for heat rejection. This precise control ensures that the engine operates within its optimal temperature window, improving combustion efficiency and reducing wear.
In chassis applications, the VG1047060005 regulator also affects the performance of the cab heater and any auxiliary cooling circuits. A malfunctioning regulator can cause engine overcooling (leading to increased fuel consumption and sludge formation) or overheating (leading to potential engine damage). Using a genuine regulator guarantees that the cooling system maintains the correct thermal balance, protecting the engine and extending its service life. It is a direct replacement for the original part in all Howo models equipped with WD615, MC11, MC13, and D10 engines.
Always replace the thermostat gasket and ensure the housing is clean before installation. Use only the recommended coolant type to prevent corrosion and ensure proper wax element operation.
Correct installation of the VG1047060005 regulator is critical to ensure proper cooling system function. Follow these steps:
Drain the coolant below the level of the thermostat housing. Remove the housing bolts and carefully separate the housing. Clean the mating surfaces thoroughly, removing all old gasket material.
Place the new VG1047060005 regulator into the housing with the correct orientation (jiggle pin usually at the highest point). Install a new gasket. Reattach the housing and tighten bolts to the specified torque (typically 20‑25 Nm).
Refill with the correct coolant mixture. Run the engine and check for leaks. Verify that the upper radiator hose becomes hot as the engine reaches operating temperature, indicating that the regulator is opening.
A failing temperature regulator can cause various cooling system issues. Common signs of wear include:
If any of these symptoms are observed, replace the regulator immediately with a genuine VG1047060005. Continuing to operate with a faulty regulator can lead to increased fuel consumption, engine sludge, and potential head gasket failure.
The calibrated wax element ensures accurate opening and closing, maintaining optimal engine temperature for fuel efficiency and reduced emissions.
By preventing overheating and overcooling, the genuine regulator reduces thermal stress on cylinder heads, gaskets, and other components, lowering maintenance costs.
Corrosion‑resistant materials and rigorous testing ensure that the regulator performs reliably for hundreds of thousands of kilometers.
To maximize the service life of your VG1047060005 regulator, follow these best practices:
By adhering to these guidelines, you ensure that the VG1047060005 regulator performs optimally throughout its intended service interval.
Aftermarket temperature regulators often use inferior wax compounds, inaccurate calibration, and poor‑quality seals, leading to incorrect opening temperatures, sticking, or premature failure. The genuine VG1047060005 is manufactured to the exact specifications of the original equipment, using precision‑formulated wax and high‑grade materials that withstand the harsh conditions of heavy‑duty diesel operation. Each unit is tested for lift, hysteresis, and leakage, guaranteeing that it will perform exactly as the original part.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its performance and resale value. The Sinotruk howo parts catalog includes a full range of cooling system components engineered for maximum reliability. For fleet managers and owner‑operators who demand the best, the genuine VG1047060005 is the only responsible choice.
The VG1047060005 temperature regulator assembly is used across a wide range of Howo models: T7H, A7, and classic Howo‑7 series equipped with WD615, MC11, MC13, and D10 engines. Always verify the thermostat housing design (some variants may have different flange diameters).
Each VG1047060005 is individually packaged in a protective box with a desiccant to prevent moisture damage. The package includes a new gasket and installation instructions. For bulk orders, regulators are supplied in sealed cartons with the OEM logo and batch traceability.
Production of the VG1047060005 takes place in ISO/TS 16949 certified facilities, using automated assembly and precision calibration equipment. Statistical process control ensures that opening temperature and lift characteristics are within a tight tolerance band.
