ATF is formulated specifically for automatic transmissions and does not possess the necessary properties for power steering systems.
Here's why using ATF instead of power steering fluid is not recommended:
- Composition Differences: ATF and power steering fluid have distinct compositions. Power steering fluid is typically a mixture of hydraulic oil, anti-wear additives, viscosity modifiers, and corrosion inhibitors, while ATF contains ingredients designed for the unique requirements of automatic transmissions.
- Viscosity: ATF generally has a lower viscosity compared to power steering fluid. Viscosity refers to the fluid's resistance to flow. Power steering systems require fluid with higher viscosity to provide adequate lubrication and resistance to thinning at higher temperatures. Using ATF with lower viscosity can result in reduced steering performance, increased wear on components, and potential leaks.
- Additive Compatibility: The additives present in ATF may not be compatible with the components and seals used in power steering systems. Using ATF can lead to the breakdown or degradation of these components, resulting in leaks, premature wear, and potential system failure.
- Warranty Concerns: Using ATF instead of power steering fluid can void your vehicle's power steering system warranty. If a problem occurs with the power steering system due to the use of ATF, the manufacturer may deny warranty coverage.
Conclusion: Given these reasons, it's crucial to use the correct power steering fluid recommended by the vehicle's manufacturer. Avoid using ATF as a substitute for power steering fluid to ensure the proper functioning, longevity, and reliability of your 1996 Ford Ranger's power steering system.
Refer to your vehicle's owner's manual or consult with a qualified mechanic for the exact power steering fluid specification for your 1996 Ford Ranger.
