The 082V06402-0115 thermostat 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 Mc 07 diesel engines.
Each 082V06402-0115 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 thermostat delivers consistent cooling system performance, reducing thermal stress on the engine and improving overall durability.

The 082V06402-0115 thermostat is installed in the coolant outlet housing of Howo Mc 07 engines, controlling the flow between the engine bypass circuit and the radiator. During cold starts, the thermostat 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 082V06402-0115 thermostat also affects the performance of the cab heater and any auxiliary cooling circuits. A malfunctioning thermostat can cause engine overcooling (leading to increased fuel consumption and sludge formation) or overheating (leading to potential engine damage). Using a genuine thermostat 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 Mc 07 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 082V06402-0115 thermostat 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 082V06402-0115 thermostat 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 thermostat is opening.
A failing thermostat can cause various cooling system issues. Common signs that replacement is needed include:
If any of these symptoms are observed, replace the thermostat immediately with a genuine 082V06402-0115. Continuing to operate with a faulty thermostat 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 thermostat reduces thermal stress on cylinder heads, gaskets, and other components, lowering maintenance costs.
Corrosion‑resistant materials and rigorous testing ensure that the thermostat performs reliably for hundreds of thousands of kilometers.
To maximize the service life of your 082V06402-0115 thermostat, follow these best practices:
By adhering to these guidelines, you ensure that the 082V06402-0115 thermostat performs optimally throughout its intended service interval.
Aftermarket thermostats often use inferior wax compounds, inaccurate calibration, and poor‑quality seals, leading to incorrect opening temperatures, sticking, or premature failure. The genuine 082V06402-0115 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.
