Understanding the Oil Light and its Causes
The oil light on your Freightliner is a vital indicator of your engine’s health. It illuminates when the oil pressure drops below a safe level, potentially leading to serious engine damage if ignored.
Here’s a breakdown of common reasons why the oil light might come on:
- Low Oil Level: The most frequent cause is simply low oil. Regularly checking your oil levels is essential for preventing this.
- Oil Pressure Sensor Malfunction: The sensor that monitors oil pressure might be faulty, triggering the light even when oil levels are adequate.
- Oil Pump Issues: A malfunctioning oil pump can’t effectively circulate oil, resulting in low pressure and the oil light coming on.
- Clogged Oil Filter: A clogged oil filter can restrict oil flow, leading to low pressure and the oil light illuminating.
- Leaking Oil: Oil leaks can drastically reduce oil levels, triggering the oil light.
