Loud engine noise accompanied by weak power is most likely caused by a cracked exhaust pipe. Reasons for loud engine noise: If the engine noise originates from the exhaust pipe, it's highly probable that the exhaust pipe is cracked and needs replacement. A high-pitched noise during high-speed engine operation may indicate aged spark plugs or clogging by debris, requiring replacement. A deep, low engine sound often signals low oil levels, which should be promptly refilled. If the engine noise changes with maximum power RPM variations, it may point to damaged engine bearings needing replacement. Metallic clanking sounds suggest potential issues with engine cylinder valves, requiring professional repair. A roaring or explosive-like noise indicates possible damage to the engine muffler, which should be replaced. Engine compartment cleaning procedure: Open the hood and cover the distributor, battery, and brake fluid reservoir with plastic sheets. Use a water spray to rinse dust and mud from the engine compartment, being careful to avoid direct water spray into the engine. Clean the air intake vents below the windshield. Use a damp cloth to remove dust, leaves, and debris from the radiator, cooling fins, and air conditioning condenser, working from the inside out. Carefully wash the support bars and dirt in the inner engine compartment. Use compressed air to blow out dust particles from the spark plug wells. Finally, dry all components thoroughly.

What is the Difference Between Water and Antifreeze?

Water and antifreeze differ in their properties: water lacks antifreeze and high-temperature resistance characteristics, whereas antifreeze possesses both. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. It prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. Many car owners believe antifreeze is only used in winter, but in fact, it should be used year-round. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year.
