If your vehicle makes an unfamiliar noise when you start the engine, you may be worrying that something is seriously wrong. If the noise goes away though, you’ve probably got nothing serious going on under the hood—especially if your engine is on the older side. After 120,000–15,000 miles (193,000–24,000 km) or so, engines often make a bit of sound when they start up. With all of that said, a vehicle that makes noise when you start it could be an early symptom of something that needs to be addressed. In this article, we’ll help you separate the problematic sounds from the normal noises.

Auto Repair & Design SpecialistBegin by starting the car and engaging the parking brake. Shift into third gear and release the clutch. If the car does not stall, it's indicative of a potential issue with the clutch. This occurs when the clutch fails to grip the spinning flywheel adequately. In a healthy clutch, the connection with the spinning flywheel would cause the car to turn off due to the increased load. Therefore, the absence of stalling suggests a slipping clutch, signifying a potential problem that needs attention. - QuestionHow can I reduce noise from my car if it's a diesel engine?Hovig ManouchekianHovig Manouchekian is an Auto Repair and Design Specialist and the Manager of Funk Brothers Auto, a family-owned business operated since 1925.
