Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Worn Belts

Tools Required: Socket set, belt tensioner tool, flashlight
Inspect the serpentine and timing belts for cracks, fraying, or significant wear.
If any belts appear damaged, proceed to remove them:
1. Loosen the belt tensioner using a tensioner tool.
2. Remove the belt from the pulleys.
3. Install the new belt by routing it according to the belt diagram.
4. Ensure proper tension is applied and secure the tensioner.

3. Check Brake System

Tools Required: Jack and jack stands, wheel chocks, torque wrench
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components:
1. Inspect brake pads and rotors for signs of excessive wear or overheating.
2. Replace any worn components such as brake pads or calipers if necessary.
3. Reassemble the wheel and lower the vehicle.

4. Inspect Exhaust System

Tools Required: Jack and jack stands, socket set
Check the exhaust system for leaks or damage:
1. Inspect all joints, gaskets, and pipes for signs of wear or corrosion.
2. If any leaks are found, replace the affected components.
3. Ensure all connections are secure and free of exhaust leaks.

5. Fluid Level Check

Tools Required: Oil dipstick, coolant reservoir check
Check the engine oil and coolant levels:
1. Remove the oil dipstick, wipe clean, and reinsert to check the oil level.
2. Inspect coolant levels in the reservoir; top off with the appropriate type of coolant if low.
3. If either fluid is low, investigate for leaks and repair as necessary.
