Why Does a Car Leak Antifreeze?

Common reasons for a car leaking antifreeze are as follows: 1. Radiator damage, poor sealing of the upper and lower water chambers. 2. Loose and poorly sealed connections at the overflow tank, water pump joint surface, and cooling system pipelines. 3. Cylinder gasket damage, excessive flatness deviation or warping of the cylinder head and block joint surface, and loose cylinder head bolts, allowing high-temperature and high-pressure gases from the cylinder to enter the cooling system, leading to rapid coolant consumption. Here is some related information: For maintenance, the coolant should be replaced every one to two years of driving. During routine maintenance, regularly check the antifreeze level and freezing point. If abnormalities are found, promptly replenish or replace it, and identify the cause of the leak for repair.

How to Determine Thermostat Failure?

Methods to determine thermostat failure are as follows: 1. Open the filler cap of the coolant reservoir and observe if there is any water flow inside. If not, it indicates that the thermostat is damaged or there is debris stuck between the main valve switch. 2. Remove the thermostat from the vehicle and place it in boiling water to observe if it opens as the water temperature rises. 3. Start the engine and after 3 minutes, feel the upper and lower radiator hoses. If the thermostat is functioning properly, the upper and lower hoses will have different temperatures—typically, the upper hose will be hot and the lower hose will be cool. The thermostat is a valve that controls the flow path of the coolant, serving as an automatic temperature-regulating device. It usually contains a temperature-sensitive component that opens or closes the flow of air, gas, or liquid through thermal expansion or contraction.

What is the principle of the clutch?

Clutch works as follows: The torque generated by the engine is transmitted to the driven plate through the friction between the flywheel, pressure plate, and the contact surface of the driven plate. When the driver depresses the clutch pedal, the diaphragm spring's large end moves the pressure plate backward through mechanical transmission, separating the driven part from the driving part. During vehicle operation, the driver can depress or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine with the transmission, thereby cutting off or transmitting the engine's power to the transmission. The clutch is a common component in mechanical transmission systems, allowing the drivetrain to be disconnected or engaged at any time.
