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.
How much fluid does a Ford PTU hold?
Capacities and Specifications
| Item | Capacity |
|---|---|
| Rear differential fluid. | 28.07 ± 1.01 fl oz (830 ± 30 ml) |
| Power Transfer Unit (PTU) fluid. | 12.7 ± 1.7 fl oz (375 ± 50 ml) |
| Automatic transmission fluid. | 12.15 qt (11.5 L)1 |
| Windshield washer fluid. | Fill as required |
How often should PTU fluid be changed?
Changing or checking the PTU lubricant is not necessary unless the unit has been submerged in water or shows signs of leakage.
How many quarts of oil does a transfer case hold?
Transfer case oil capacity varies significantly by vehicle, but typical amounts range from around 1.5 to 2 quarts. To find the exact capacity for your vehicle, you must consult your owner's manual, as some models may require more or less fluid. It is crucial not to overfill the transfer case, so filling it until the fluid just begins to seep out of the fill plug is a common practice.
Approximate capacities for common vehicles
- Toyota Tundra: 1.5 to 1.6 quarts for 2013-2021 models; 1.12 to 1.2 quarts for 2007-2012 models.
- Ford F-250/F-350 (2011-2016): 2 quarts.
- Ford F-250/F-350 (2017-2020): 1.9 to 2 quarts.
- Chevrolet Silverado/GMC Sierra (2019-2024): 1.6 quarts.
General advice for any vehicle
- Consult your owner's manual: The most accurate information for your specific vehicle is in its owner's manual.
- Fill to the correct level: Once you have the correct fluid, add it until it starts to flow out of the fill plug, then stop.
- Do not overfill: Overfilling can damage the seals and other components of the transfer case.
- Use the correct fluid: Always use the type of oil recommended by the manufacturer. Some transfer cases require specialized fluids, such as a GL4 rated oil, while others can use a GL5.
