Common causes of dodge challenger rattling noise

Common causes of dodge challenger rattling noise

If your dodge challenger is emitting loud rattling noise when driving, consider finding the leading cause of the issue. Some of the leading causes include the following;

1. Loose timing chains

As you keep driving several times, the timing chains may become loose, and once they become loose, there will be an emission of rattling noise. You will notice the noise once you start driving your car. Also, if you have a faulty tensioner, it may leave the timing chains falling off throughout the journey. Sometimes you may hear the noise while starting the car, and sometimes you may fail to hear any.

2. Loose accessories

Another common cause of the rattling noise is loose accessories. Once the accessories become loose, they start falling off, resulting in some rattling noise. Also, if you accidentally leave some accessories such as a valve cover on top of the intake, they start emitting the rattling noise while driving.

3. Insufficient oil

Low or no oil in the engine results in some rattling noise, indicating that it is slowly losing its powers and dying. Be cautious about the car engine and ensure it has oil throughout.

4. The heat shield is flimsy

The heat shield is the primary driver of the rattling sound in the exhaust system since it becomes looser over time as they wear and collect miles. The exhaust system would always generate a rattling noise when the heat shield accumulates once on the exhaust. Try opening the motor in idle and releasing off the accelerator pedal to hear the rattling sounds caused by the heat shield.

5. Faulty catalytic converter 

A car’s catalytic converter is suitable for eliminating impurities from the exhaust system. If a converter becomes worn, its metals might corrode, resulting in a rattling noise. Catalytic converter problems are easily noticeable because the motor will show a signal to see while the light is already on.

6. The exhaust system is leaking

Whenever the exhaust system leaks, a rattling noise is heard, which some people refer to as a clicking noise. To determine where the exhaust system is failing, look at the bolt places that link it to the cylinder at the exhaust and see if the bolts are loosened, allowing gases and oil to leak and cause the sound. Its most prevalent source of rattling noise for most cars is the expanding exhaust system.

4. Disconnect the drive belt’s parts

Find the wiring schematic in the instruction booklet. It’s usually found beneath the car’s hood. The tightening strap should then be withdrawn. To replace S-belts, squeeze the spring-loaded fastener.

Change the angle of one of the belts to disconnect the V-belts or multi-design belts. Once the strain is relieved, the pulleys will readily slide off another pulley.

5. Disconnect the timing chain

Unscrew the timing chain covering from the engine before dismantling it. Identify where the camshaft and crankshaft are situated. 

6. Replace the timing chain

Loosen the gearbox with a decent handful of motor grease before putting the new chain. It will ensure that the new gears and timing chain work at their best for the most extended period feasible. Afterward, when, you can put a new timing chain in position. Ensure the new chain is perfectly aligned with the old chain’s markings on the gearing. After that, lock the chains.

7. Reconstitute the belt tensioner and cooling system’s parts

Begin by installing the harmonic stabilizer. For specs, always consult the instruction booklet. Reinstall the water pump correctly. Attach the heater lines to the water pump after that.
