How much oil does a Ford Edge PTU hold?
The Ford Edge's Power Transfer Unit (PTU) typically holds around 1.5 quarts (1.4 liters) of gear oil. This is the recommended amount of oil to maintain proper lubrication and operation of the PTU in a Ford Edge vehicle.
What is a PTU and Why is it Important?
The Power Transfer Unit (PTU) is a component found in all-wheel-drive (AWD) and four-wheel-drive (4WD) vehicles, including the Ford Edge. The PTU is responsible for transferring power from the transmission to the front and rear axles, allowing the vehicle to distribute torque to all four wheels as needed for improved traction and handling.
Maintaining the proper oil level in the PTU is crucial for its smooth and efficient operation. If the PTU is low on oil, it can lead to increased wear and tear on the internal components, potentially causing expensive repairs down the line. Conversely, overfilling the PTU with too much oil can also cause issues, such as increased drag and reduced fuel efficiency.
How to Check and Maintain the PTU Oil Level
- Locate the PTU drain and fill plugs, usually accessible from the underside of the vehicle.
- Use a torque wrench to loosen the fill plug and check the oil level. The oil should be level with the bottom of the fill hole.
- If the oil level is low, add the recommended gear oil (typically a synthetic 75W-90 or 80W-90 lubricant) until it begins to drip from the fill hole.
- Tighten the fill plug back to the specified torque setting, usually around 18-22 ft-lbs (24-30 Nm).
- Periodically check the PTU oil level, typically every 30,000 miles (48,000 km) or as specified in the Ford Edge owner's manual.
Maintaining the proper PTU oil level is an important part of regular Ford Edge maintenance, helping to ensure the longevity and optimal performance of this critical all-wheel-drive component.
