When it comes to vehicle maintenance, we often think of oil changes and tire rotations. However, there are several other crucial parts that often are overlooked maintenance items. Regular maintenance of these components can ensure your vehicle runs smoothly and efficiently.  In this month’s blog post, we examine those five overlooked parts, their function, and ways to keep them maintained.

1. Cabin Air Filters Cabin air filters keep the air inside your vehicle clean by trapping dust, pollen, and other contaminants. When neglected, a dirty filter can lead to reduced airflow and an unpleasant odor inside the cabin. To keep your cabin air fresh, replace the filter every 15,000 to 30,000 miles, or as recommended by your vehicle’s manufacturer.  It’s always wise to have it checked during routine oil changes.

2. Differential Fluid The differential fluid lubricates the gears in your vehicle’s differential, which is responsible for distributing power to the wheels. Over time, the fluid can become contaminated, leading to gear wear and potential failure. It’s essential to check and replace the differential fluid every 30,000 to 60,000 miles, depending on your driving conditions.

3. PCV Valves Positive Crankcase Ventilation (PCV) valves regulate the pressure and remove gases from the engine crankcase. A clogged or malfunctioning PCV valve can cause increased oil consumption and engine performance issues. Inspect and replace the PCV valve every 20,000 to 50,000 miles to maintain optimal engine function.

4. Fuel Injectors Fuel injectors are responsible for delivering fuel into the engine’s combustion chamber. Dirty or clogged fuel injectors can lead to poor engine performance and reduced fuel efficiency. Regular use of fuel injector cleaner and periodic professional cleaning can keep them functioning properly.

5. TPMS Sensors Tire Pressure Monitoring System (TPMS) sensors alert you when your tire pressure is low. Faulty TPMS sensors can give inaccurate readings, leading to unsafe driving conditions. Check the sensors during regular tire maintenance and replace them as needed to ensure accurate tire pressure monitoring.
