What happens when the engine water passage is blocked?
2 Answers
Car radiator blockage can cause poor cooling in the cooling system, leading to excessive engine temperature and vehicle damage. Engine radiator rust and scaling: Rust and scale can restrict the flow of antifreeze in the cooling system, reducing heat dissipation and causing engine overheating, which may even lead to engine damage. Oxidized antifreeze can also form acidic substances, corroding the metal parts of the radiator and causing leaks or breakage. Solution: The solution to radiator problems mainly lies in routine daily inspections. Regularly check the radiator for leaks or rust, and clean, replace, or add antifreeze on time to increase the boiling point and extend its service life.
As a car owner, I once experienced a blocked engine coolant passage while driving. The temperature gauge suddenly shot up to the red zone, warning lights flashed frantically, and it almost scared me to death. The car's power noticeably weakened, feeling sluggish when accelerating, and I soon felt the engine area getting hot and steaming. I had to pull over immediately. The blockage was likely due to accumulated scale or deteriorated antifreeze forming clumps, obstructing coolant flow and preventing proper engine cooling. If I had continued driving, the high temperature could have caused cylinder head deformation, piston damage, or even total engine failure, with repair costs easily running into thousands. Since then, I've made it a habit to regularly check coolant levels, replace antifreeze every two years, and clean the radiator and pipes during car washes. Don't underestimate this issue – catching symptoms early can save you a lot of trouble.
