How to Identify and Fix Honda Accord Loud Engine Noise

AvatarByCarl Frisch

Honda Accord is a popular sedan that has been in production since 1976 and is known for its reliable performance and efficiency. However, some owners have reported loud engine noise coming from their Honda Accord. This noise can range from a light ticking to a loud roaring sound that can be heard both inside and outside of the car. The cause of this engine noise can vary, but it is typically caused by an issue with the exhaust system, worn out motor mounts, or a faulty timing belt. In order to fix the issue, it is important to diagnose the exact cause and then make the necessary repairs to resolve the issue.

Automobile: Honda Accord Loud Engine Noise

Unusual Ticking Noise

Ticking noises coming from an engine are generally caused by a lack of lubrication or friction between two metal parts. This can be due to worn out parts, such as lifters or valvetrain components, or low oil levels in the engine. In some cases, it could also be caused by a faulty timing chain and tensioner. To diagnose the cause of this noise, it is important to identify the location of the sound and then inspect the related engine components for wear and tear.

Rattling Noise

A rattling noise coming from underneath the hood of a Honda Accord could be a sign of a loose exhaust system or broken heat shield. The heat shield protects the bottom of the vehicle from hot exhaust gases, and if it is broken or loose, it will cause a rattling sound when driving over bumps in the road. To fix this problem, it is important to inspect and tighten any loose connections in the exhaust system and replace any damaged components.

Squealing Noise

Squealing noises can often be traced back to worn out belts in an engine, such as the drive belt or fan belt. These belts are responsible for driving various components in an engine, such as fans and pumps, and if they become worn out they can start to slip and squeal when running. It is important to inspect these belts for signs of wear and tear and replace them if necessary.

Grinding Noise

Grinding noises coming from an engine can indicate a number of different issues with your Honda Accord’s internal components. In most cases, this type of sound is caused by worn out bearings or other parts that are no longer functioning properly due to age or lack of lubrication. It is important to identify where exactly this noise is coming from before attempting any repairs – if it sounds like it’s coming from inside the engine block then you may need to take your car into a professional mechanic for further inspection.

Low Oil Level

One of the most common causes of loud engine noises in Honda Accords is a low oil level. If the oil level is too low, it can cause parts to grind against each other, resulting in a loud and sometimes unpleasant noise from the engine. To check the oil level, you should first locate the dipstick. Once you have located it, pull it out and wipe it clean with a cloth or paper towel. Reinsert the dipstick and pull it back out to check the level. If the oil appears to be at least halfway up on the dipstick, then there is enough oil for proper operation. If not, you will need to add more.

Leaking Exhaust System

Another possible cause of loud engine noises in Honda Accords is a leaking exhaust system. This can happen if there are any cracks or holes in any of the pipes or components of your exhaust system. To check for this issue, you should start by inspecting all visible parts of your exhaust system for signs of damage or wear and tear. If you notice any cracks or holes, then this could be causing your loud engine noises and should be inspected and repaired as soon as possible by a qualified mechanic.

Belts and Pulleys Issues

Finally, another possible cause of loud engine noises in Honda Accords is an issue with your belts and pulleys. Belts and pulleys are used to transfer power from one part to another within your engine compartment, so if they become loose or worn out they can create a loud noise when running. To inspect them properly, you should first locate all belts and pulleys in your engine compartment – usually near the top near where your air filter is located – and inspect them for signs of cracking or fraying. If any are found, they should be replaced as soon as possible by a qualified mechanic to ensure that they do not create further issues with your Accord’s engine performance.
