Here's why:
* Fluid Type: There are different types of power steering fluids (hydraulic fluid), and the wrong one can damage your system. Your truck's manual will specify the correct type.
* Year and Model: Even within the M2 model, there can be variations in steering systems and fluid requirements based on the year and specific configuration.
* Service History: The condition of your existing power steering fluid and the history of its maintenance can also impact the type recommended.
Here's what you should do:
1. Consult Your Owner's Manual: The most reliable source for this information is your truck's owner's manual.
2. Contact a Freightliner Dealer or Mechanic: A certified Freightliner technician can provide you with accurate guidance on the right power steering fluid for your specific vehicle.
3. Check the Fluid Reservoir: If you're unsure, look at the reservoir for your power steering fluid. It may have a label indicating the type of fluid it requires. However, be cautious as this may not always be accurate.
Important Note: Using the wrong power steering fluid can lead to costly damage to your steering system. It's better to be safe than sorry and consult a professional for this information.
