⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow engine components to cool before touching to prevent burns.

Symptoms

•Burning rubber odor, particularly while driving or shortly after stopping
•Overheating engine or temperature gauge rising
•Visible smoke or burnt material around the engine bay or wheel wells
•Diminished performance or unusual noises from the engine or drivetrain

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Allow the engine to cool before starting any work.

2. Inspect and Replace Belts

Sub-steps:
1. Open the hood and visually inspect serpentine and timing belts for cracks, fraying, or wear.
2. If damage is found, remove the old belt by loosening the tensioner using a socket wrench.
3. Install the new belt according to the routing diagram typically found on the engine cover.
4. Check and adjust the tension of the new belt as needed.
Tools Required:
- Socket set
- Wrench set
- Torque wrench (if specified by manufacturer)

3. Inspect Tires and Alignment

Sub-steps:
1. Inspect tires for uneven wear patterns, cracks, or bulges that could indicate a problem.
2. Check tire pressure and inflate to the manufacturer's specifications.
3. If wear is abnormal, consider a wheel alignment and rotation.
Tools Required:
- Tire pressure gauge
- Jack and jack stands (if needed for tire inspection)

4. Check for Leaks

Sub-steps:
1. Visually inspect under the vehicle and around the engine for any oil or fluid leaks.
2. Clean any spilled fluid and monitor for reoccurrence.
3. If leaks are found, identify the source and replace seals or gaskets as needed.
Tools Required:
- Rags for cleaning
- Pliers or socket set for seal replacement (if applicable)

5. Brake System Inspection

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for excessive wear and the caliper function.
3. Replace pads if they show significant wear and ensure calipers are not sticking.
Tools Required:
- Jack and jack stands
- Lug wrench
- Brake tool kit
