When should the flywheel be replaced?

Not sure when to change the flywheel? What are the symptoms of an HS flywheel? In this article, we'll explain everything you need to know about replacing a flywheel to prevent further damage.

🗓️ How long is the service life of my flywheel?

The flywheel is a durable part, designed for a mileage of more than 200 kilometers. However, note that a dual mass flywheel has a shorter life than a rigid model.

If it fails up to 100 km, contact the manufacturer. Repair costs can be partially and sometimes even fully covered.

🚗What are the features of the HS flywheel?

There are several symptoms that can signal an HS flywheel, although it is not necessary to be sure that this particular part is faulty.

Vibration on the clutch pedal

The HS flywheel often causes strong vibrations in the engine block and clutch pedal. These fluctuations can have different causes, but most often the flywheel is to blame.

Difficult gear shifting

When the engine is running at low rpm, gear changes can be difficult. Attention, this can damage the clutch! If at the same time you observe vibration and clicks when engaging the clutch, there is no longer any doubt that your flywheel is out of order.

Idle clutch click

Another symptom that can occur with an HS flywheel is a clicking sound that can be heard when you depress the clutch at idle. Be careful !

🔧 How to check the condition of the flywheel?

Several signs indicate poor flywheel condition, such as strong vibrations at the clutch pedal level, clicks at idle speed, or difficulty shifting gears.

You can also perform a self test using the TDC sensor. Also called a crankshaft sensor, it can give you a DTC back by providing some information about circuit faults that could be caused by an abnormality in the flywheel.

However, be careful with two things: the sensor may be faulty. On the other hand, the trouble codes returned by the TDC sensor may have different meanings. To decipher them, it is best to seek professional advice.

🇧🇷 How to increase flywheel life?

Since the flywheel is directly connected to the clutch and often interacts with it, the wear rate of the flywheel depends on the wear of the clutch. Otherwise, the reasons for wear are similar. Use neutral as soon as possible and without moderation. Avoid traffic jams and short city trips whenever possible, drive with care and respect for mechanical parts, avoid jerks, and shift gears calmly.

⚙️ Should the flywheel be replaced at the same time as the clutch kit?

If your vehicle has a rigid flywheel, you do not need to replace it with the clutch kit. Conversely, with a dual-mass flywheel, we recommend doing this.

Little trick: in case of replacement, we advise you to opt for a rigid engine flywheel, a classic model, and not a dual-mass one; its life expectancy is longer and it causes less worries.

💰How much does it cost to replace a flywheel?

Replacing a flywheel is very expensive, especially since the entire clutch kit needs to be replaced with it. This is explained by the high labor intensity, up to 9 hours for some cars and the price of a part, sometimes more than 1000 euros for a new flywheel.

So count between € 150 and € 2400 for a flywheel and clutch replacement including parts and labor. Considering the amounts, it is best to compare prices in garages near you.

Even if your flywheel has a long life, check it as soon as the first symptoms appear. If he's HS, make an appointment with one of our Reliable mechanics.
