Slipping clutch: symptoms and when to replace it

- Comments Off on Slipping clutch: symptoms and when to replace it
The clutch slips when engine revs rise without the speed increasing accordingly, typically uphill or in fourth and fifth gear. It is progressive wear that must be dealt with before the disc ruins the flywheel.
The practical test
Safely, with the car moving at low speed in a high gear (fourth), accelerate firmly: if the revs rise quickly but the car does not accelerate in proportion, the clutch is slipping.
Typical symptoms
- Revs rising without thrust
- Acrid burning smell after climbs or traffic
- Very high release point
- Vibration when setting off
- Difficulty engaging gears (often the release bearing or the slave cylinder)
Causes of premature wear
- Driving with the foot resting on the pedal
- Sporty starts and frequent towing
- Oil leaks from the engine or gearbox seal contaminating the disc
- Increased power without an adequate clutch
What to replace together
It is best to replace the complete kit (disc, pressure plate, release bearing) and check the condition of the flywheel: if it is a dual-mass unit with play or noise, replacing it at the same time should be considered so the job is not done twice.

Frequently asked questions
How long does a clutch last?
Highly variable: from 60,000 km with intense urban use to over 200,000 km with relaxed, out-of-town driving.
How do you tell whether the clutch is slipping or it is the gearbox?
If the revs rise without an increase in speed it is the clutch. If the gears grind or will not engage, the problem is more often in the linkage or the gearbox.
Should the flywheel be replaced too?
If it is a dual-mass unit with excessive angular play or noise, yes: replacing only the clutch often means doing the job again.
