• 【Advantages】: Made of high-quality plastic and aluminum, the plastic shell is upgraded to a sturdy metal structure to prevent premature damage in the gasket area, so that it can withstand extreme temperature changes and prevent cracking.
• 【Function 1】: After rigorous hardness and compression testing, the structure is precise and the performance is reliable. More effectively regulate the heat dissipation capacity, ensure that the internal parts work within the appropriate temperature range and remain at the optimal temperature, which helps to run more smoothly, enhance cooling protection, and extend service life.
• 【Function 2】: The function of the thermostat and housing assembly is to regulate the flow of coolant through the radiator to maintain a stable operating temperature, prevent overheating, reduce wear and deposits, and ensure optimal cooling efficiency and vehicle performance.
• 【Replace the thermostat】: Symptoms of a damaged or faulty thermostat: The temperature reading is too high and the internal parts are overheated; the temperature reading is too low and the temperature of the internal parts is too low; the temperature changes are unstable; the coolant flows out around the thermostat housing or under the vehicle. If a fault code appears, please replace it immediately to ensure the smooth operation of the car.
