The solution for the abnormal noise when starting the FAW Toyota Prado is to clean the oil mixture and carbon deposits in the intake tract. The reason is that carbon deposits on the car's throttle affect the smoothness of acceleration. There are two methods for cleaning the throttle: disassembly cleaning and non-disassembly cleaning. After cleaning, the throttle opening must be reset; otherwise, the engine may experience unstable idling or excessively high RPM. Taking the 2019 FAW Toyota Prado Premium Edition as an example, its body dimensions are: length 4840mm, width 1885mm, height 1880mm, with a wheelbase of 2790mm. It is equipped with a 3.5L naturally aspirated engine, delivering a maximum horsepower of 280PS, maximum power of 206kW, maximum torque of 365Nm, paired with a 6-speed automatic transmission.
When I first drove my Prado, I also encountered strange noises during startup. The common causes for this are usually wear on the starter motor or a loose belt. In my case, the noise sounded like a clicking sound, which turned out to be the starter motor gear not fully engaging. After a check at the 4S shop, it was confirmed, and replacing the new motor solved the issue. If the noise is more of a squeaking sound, it’s likely due to an aging belt. You can test the belt tension by pressing it with your hand—if it’s too loose, take it to the shop for tension adjustment or a new belt. Additionally, loose battery terminals can also cause strange noises during startup, so ensure the terminals are tight and free from rust. For prevention, I regularly have technicians lubricate the starter system components during maintenance and keep the car parked in a dry place to minimize corrosion. Don’t overlook startup noises—they hint at potential faults. Delaying repairs could affect the entire engine. Once they appear, get them diagnosed and fixed at a professional repair shop to ensure safe and trouble-free driving.
