The air filter prevents dirt and debris from entering the engine. A clean air filter improves fuel efficiency and engine performance. It should be replaced every 20,000 miles.
Cabin Air Filter Replacement
The cabin air filter ensures that the air inside your vehicle remains clean. Replacing it regularly helps maintain a healthy cabin environment and improves the efficiency of the HVAC system.
Coolant Replacement
Coolant prevents the engine from overheating and protects against corrosion. It is essential to replace the coolant every 30,000 miles to maintain optimal engine temperature.
Common Issues and Troubleshooting
Even with regular maintenance, issues may arise. Here are some common problems and how to troubleshoot them:
- Engine Warning Light: Check the oil level and ensure that all fluids are topped up. If the light persists, consult a professional.
- Braking Issues: If you notice squeaking or reduced braking performance, inspect the brake pads and fluid levels.
