Never use transmission fluid in a power steering system. They are incompatible fluids and using the wrong fluid can damage your power steering system.
Here's why:
* Different properties: Power steering fluid is specifically designed to lubricate and cool the power steering system, and it's formulated to handle the high pressures involved. Transmission fluid is designed for the different demands of a transmission.
* Compatibility issues: Mixing the two fluids can cause them to separate, leading to clogs and blockages in the system.
* Damage: Using transmission fluid in your power steering pump can lead to serious damage, including pump failure, leaks, and reduced steering performance.
Always refer to your Jeep Liberty's owner's manual for the specific power steering fluid recommended for your vehicle.
