How Often Should Engine Mounts Be Replaced?
2 Answers
Engine mounts should be replaced approximately every 100,000 kilometers. The function of an engine is to convert the thermal energy of gasoline into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the piston to perform work. The main components of an engine include: 1. The valve train; 2. The crankshaft and connecting rod assembly; 3. The ignition system; 4. The cooling system; 5. The lubrication system; 6. The fuel supply system. Engine maintenance tasks include: 1. Regularly changing the engine oil and oil filter; 2. Maintaining good crankcase ventilation; 3. Periodically cleaning the crankcase; 4. Regularly cleaning the fuel system; 5. Routine maintenance of the radiator; 6. Cleaning and maintaining the fuel system.
Honestly, there's no fixed interval for replacing engine mounts. I've been driving this old Jeep for almost eight years, clocking nearly 120,000 kilometers, and just had it inspected at the repair shop last week. The mechanic said the rubber in the mounts was cracked and warned that if not replaced soon, the engine would shake severely and damage other components. From my experience, city roads with potholes and frequent bumps accelerate mount wear, so I'd recommend checking them every 60,000 to 100,000 kilometers or roughly every five years. Newer cars might last longer, but older vehicles like mine need more frequent inspections. A single repair can easily cost several thousand yuan. Pay attention to increased vibrations while driving—like steering wheel shaking at idle—as that's your cue to act. Don't let minor issues escalate into major problems that harm your car and compromise safety.
