What Causes Engine Coolant Consumption?

[ThomasFitz]

Engine coolant consumption can be attributed to: 1. Natural depletion; 2. Cracks in the antifreeze cylinder block, or burning/corrosion deformation of the cylinder gasket. Functions of coolant: 1. Provides anti-corrosion protection for cooling system components; 2. Prevents scale buildup to maintain radiator efficiency; 3. Ensures the engine operates within normal temperature ranges. The engine's function is to convert the thermal energy of gasoline into mechanical energy by expanding gases through combustion in a sealed cylinder, thereby driving the piston to perform work. Engine maintenance methods include: 1. Using qualified engine oil; 2. Using qualified coolant/antifreeze; 3. Regularly cleaning radiator scale; 4. Periodically removing engine carbon deposits; 5. Routine replacement of the three automotive filters; 6. Maintaining appropriate operating RPM.
