What is the solution for a faulty thermostat?

The solution for a faulty thermostat is: 1. After starting the engine, check if there is water flow in the cooling tank; 2. Inspect whether there is water flow at the inlet pipe of the radiator; 3. Observe the water temperature gauge to see if it shows any abnormalities. The reasons for a faulty thermostat are: 1. The opening and fully open temperature of the valve is too high; 2. The warm-up time is prolonged, and when the car is at a lower water temperature, the combustion gases and condensed water on the cylinder walls form acidic substances that corrode the cylinders; 3. Liquid fuel and water wash away the lubricating oil film on the cylinder walls, leading to wear on the cylinder liners and piston components; 4. Excessive temperature fluctuations between cold and hot states cause frequent contraction and expansion of the cylinder block, resulting in the detachment of adhesive patches or glue, leading to diesel engine malfunctions.
I found the thermostat is broken, really can't delay fixing it. This thing controls the engine temperature, if it malfunctions, the engine may overheat and get damaged. Common symptoms include the temperature gauge fluctuating or the engine taking unusually long to warm up with a sudden increase in fuel consumption. I drove straight to the repair shop to get it replaced, usually costing 200-400 RMB. Before the repair, avoid long-distance driving to prevent engine failure. Regularly checking the coolant level and quality can prevent similar issues. This job isn't too complicated, but without the right tools and experience, don't attempt it yourself to ensure safe driving.
