Where can I find the production date of a car engine?

[Adelyn]

The production date of a car engine is indicated on the metal plate in the engine compartment. Inside the engine compartment, there is an aluminum car plate that displays the car's serial number, engine displacement, model, brand, and the important specific production date. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning the expanded gas in a sealed cylinder to push the piston. Below are the maintenance methods for car engines: 1. Use qualified engine oil. 2. Use qualified coolant and antifreeze. 3. Regularly clean the radiator scale. 4. Regularly clean engine carbon deposits. 5. Regularly replace the car's three filters. 6. Maintain a reasonable engine speed.
