How Much Does A Flywheel Replacement Cost in the UK?

Typically located in between the engine and the clutch/transmission in the engine compartment, the flywheel is a heavy metal disc that sits on the crankshaft. As the crankshaft turns, the flywheel turns with it. The flywheel stores energy and helps keep the engine running smoothly. If your vehicle is fitted with a dual mass flywheel they are usually replaced when they are damaged, are causing vibrations or have become noisy. When a clutch is worn or needs replacement, the flywheel is usually inspected for cracks, damage or excessive free play and replaced if found to be outside of recommended specification.

How much does it cost to replace a flywheel?

The average cost of replacing a flywheel is £875, with prices ranging from £650 and £1200. Changing the clutch usually involves replacing the flywheel as not replacing the flywheel at the same time may then lead to damage to the new clutch. When replacing the flywheel, the clutch is also replaced to ensure a trouble-free service life. While this may increase the cost of the repair, it is still more cost-effective in the long run to replace both at the same time. The exact price of the flywheel replacement depends largely on your car and the parts your car's manufacturer recommends.

Your location can also be a key factor in determining the price of a flywheel replacement. For example, average hourly labour rates and demand in cities like London is around £50-£100 while in towns with lower demand, the labour rates can range from £35-£50. The type of mechanic, for example, a mobile mechanic vs a dealership garage technician can also affect the total cost of a flywheel replacement.

Signs your flywheel needs to be replaced

• Difficult starting the car
• Burnt or pungent smell
• Clutch slippage
• Grinding or scraping noises when clutch is engaged
• Vibration from the clutch pedal
• Inconsistency when accelerating
• More effort or trouble when changing gears

Noise and vibration

Vibrations through the vehicle and clutch pedal when the vehicle is idling or when pulling away can be a sign of dual mass flywheel failure. Other symptoms include rattling noises that go when you depress the clutch and a rough engine idle that can sound like a misfire

Clutch slipping

Clutch slippage occurs when the clutch is not fully engaging the engine to the transmission. This can be caused by a number of things, including a worn clutch, incorrect clutch adjustment, or even a damaged flywheel

Burnt smell

Using the clutch inappropriately can lead to excessive heat, wear and increased friction with the flywheel causing it to emit a pungent ‘burnt’ odour.

Trouble starting the car or idling

If the flywheel ring gear is damaged, it could lead to starting problems. The flywheel connects the engine crankshaft to the transmission and starter motor. If the flywheel is damaged, it can cause the engine to stall or fail to start.
