What is the replacement interval for engine mounts?
3 Answers
Engine mounts do not have a fixed replacement interval; they need to be replaced when damaged. Some vehicles may not require replacement even after 100,000 kilometers, while others may need replacement after just 20,000 to 30,000 kilometers. Symptoms of damaged engine mounts include: 1. Jerking or hesitation when driving at low gears with high torque, as well as similar sensations when reversing; 2. Noticeable engine vibration when starting the vehicle or turning on the air conditioning, and significant steering wheel vibration at high speeds. The main components of an engine include: 1. Valve train; 2. Crankshaft and connecting rod assembly; 3. Ignition system; 4. Cooling system; 5. Lubrication system; 6. Fuel supply system. Engine maintenance tasks include: 1. Regular oil and oil filter replacement; 2. Maintaining proper crankcase ventilation; 3. Periodic crankcase cleaning; 4. Regular fuel system cleaning; 5. Routine radiator maintenance; 6. Fuel system servicing and cleaning.
Regarding the replacement cycle for engine mounts, as an ordinary car owner with over a decade of driving experience, I'd like to share some real-world insights. In truth, there's no fixed replacement interval or mileage for mounts—it largely depends on your driving habits and vehicle condition. I last replaced mine around 80,000 kilometers because frequent rough-road driving severely aged the rubber mounts. At idle, the car shook like a seismograph, accompanied by strange noises. Stop-and-go city traffic accelerates wear even faster. My advice: during 80,000–100,000 km maintenance, have technicians check the mounts' elasticity for cracks or looseness. If you notice excessive engine vibration or squeaking during acceleration, address it promptly. Delaying could compromise the entire engine system and increase repair costs. Regularly monitor engine smoothness on flat roads—timely maintenance prevents issues.
The replacement interval for engine mounts truly varies from person to person, with no rigid rules. Having driven several cars myself, I've found that replacement is only necessary when symptoms appear, such as significantly increased body vibration during engine startup or a noticeable wobbling sensation when accelerating. Driving habits play a crucial role—those who frequently undertake long-distance trips or carry heavy loads will experience faster mount wear. I recommend inspecting the condition of the mount rubber every 50,000 kilometers. During routine maintenance, keep an eye out for signs of cracking or hardening. Don't overlook minor symptoms like sudden increases in noise, as they may indicate damage to other engine components. When it comes to car repairs, don't take chances—beginners should avoid DIY attempts and opt for professional shops instead. Cultivating good driving habits, such as gentle starts and stops, can extend the lifespan of mounts, saving both money and hassle.
