- Remove the affected component, clean the surface, and install a new gasket.
- Torque the bolts to the manufacturer's specifications.

4. Check and Replace Brake Components

Tools required: Jack, jack stands, socket set, brake cleaner.
Inspect brake pads and rotors for overheating signs.
If pads are worn, replace them; ensure rotors are also in good condition.
- Remove the wheel, then the caliper, and replace pads as needed.
- Reassemble and torque bolts appropriately.

5. Coolant System Maintenance

Tools required: Coolant funnel, radiator cap removal tool.
Check the coolant reservoir for low levels; refill with the appropriate coolant.
Inspect hoses for leaks or damage; replace if necessary.

6. Electrical Inspection

Tools required: Multimeter, electrical tape.
