Signs your clutch needs repair or replacement:
* Slipping: The engine revs high while the car accelerates slowly. This means the clutch isn't fully engaging.
* Difficult Engagement: The clutch pedal feels hard to press or doesn't disengage smoothly. It might feel spongy or have a high bite point (very close to the floor).
* Clutch Pedal Goes to the Floor: The pedal goes all the way to the floor without resistance, indicating a hydraulic system problem or a broken cable (depending on your model's setup).
* Burning Smell: A distinct burning smell, often associated with a burnt clutch smell, indicates severe clutch wear.
* Grinding Noise: A grinding noise when engaging the clutch, especially when starting, signifies damage to the clutch disc or pressure plate.
* Clutch Dragging: The engine feels like it's working hard even when the clutch is disengaged. This is a sign of a problem with the clutch release mechanism.
How to replace a clutch (general steps, NOT a complete guide):
This is a highly simplified overview. A detailed repair manual specific to your 1991 Mercury Tracer is absolutely necessary. These manuals provide torque specifications, diagrams, and crucial steps that cannot be covered here.
1. Safety First: Disconnect the negative battery terminal. Support the vehicle securely on jack stands.
2. Drain Transmission Fluid: Completely drain the transmission fluid.
3. Remove Transmission: This is the most challenging part. It involves disconnecting various components connected to the transmission (driveshafts, shift linkage, etc.). You'll likely need to support the transmission with a transmission jack.
4. Clutch Removal: Once the transmission is removed, you'll be able to access the clutch assembly. Carefully remove the pressure plate, clutch disc, and throw-out bearing.
5. Clutch Installation: Install the new clutch disc, pressure plate, and throw-out bearing, ensuring correct alignment and proper torque for all bolts.
6. Transmission Reinstallation: Carefully reinstall the transmission, ensuring all connections are made correctly.
7. Refill Transmission Fluid: Fill the transmission with the correct type and amount of fluid.
8. Bleed the Clutch Hydraulic System (if applicable): If your Tracer has a hydraulic clutch system, you'll need to bleed the system to remove any air bubbles.
Tools you'll need (this is not an exhaustive list):
* Jack and jack stands
* Transmission jack
* Socket set (metric)
* Wrenches (metric)
* Torque wrench
* Clutch alignment tool
* Pry bars
* Screwdrivers
* Drain pan
* New clutch kit (pressure plate, clutch disc, throw-out bearing)
* Repair manual specific to your 1991 Mercury Tracer
