Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Brake Components

Remove Wheel:
- Use a jack to lift the vehicle and secure with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Brake Pads and Rotors:
- Check for excessive wear on pads and rotors. Replace if thinner than 3mm.
- Look for signs of overheating (blue discoloration) on the rotors.
Replace Brake Pads & Rotors (if necessary):
- Remove the caliper bolts and slide the caliper off the rotor.
- Replace brake pads and install new rotors if needed.
- Reinstall caliper and torque bolts to manufacturer specifications (typically 25-30 ft-lbs).

3. Check and Replace Fluid Levels

Transmission Fluid:
- Locate the transmission dipstick and remove it to check fluid level.
- If low or burnt, drain and replace with manufacturer-recommended fluid.
- Torque the transmission pan bolts to specifications (typically 12-15 ft-lbs).
Coolant:
- Inspect coolant level in the reservoir. If low, top off with a 50/50 mix of OEM coolant.
- Check for leaks in hoses or radiator.

4. Inspect Belts and Hoses

Visual Inspection:
- Check all belts for cracks, fraying, or glazing.
- Inspect hoses for leaks or bulges.
Replace if necessary:
- Use a wrench to remove tension from the serpentine belt and slide off.
- Replace with a new belt, ensuring proper routing and tension.

5. Final Assembly

Reinstall the wheel and lug nuts, tightening to specified torque (typically 100-150 ft-lbs).
Reconnect the battery.
