Here's why it's a problem and what needs to be done:
* Incompatible Fluids: Automatic transmission fluid (ATF) and power steering fluid are chemically different. ATF is not designed for the seals and components in a power steering system. Mixing them can cause:
* Seal damage: ATF can swell or dissolve the seals in the power steering pump, rack and pinion, and hoses. This leads to leaks and eventual failure of the system.
* Pump damage: The power steering pump is not designed to handle ATF's different viscosity and properties. This can cause overheating, seizing, and complete pump failure.
* Corrosion: ATF can be corrosive to certain metals used in the power steering system, leading to accelerated wear and tear.
* Reduced Performance: The power steering will likely feel sluggish, stiff, or even fail completely.
* Removal: The power steering system needs to be thoroughly flushed. This usually involves:
* Draining the reservoir: Completely drain the power steering fluid reservoir.
* Flushing: Using a power steering flush machine (professional mechanic recommended) or repeatedly draining and refilling with new power steering fluid is necessary to remove as much ATF as possible. This process often requires multiple cycles.
* Inspection: After flushing, a mechanic should carefully inspect the system for any leaks or damage to the seals, pump, or hoses. Damaged components may need replacement.
* Refilling: Once the system is clean and free of leaks, it should be refilled with the correct power steering fluid specified for your 1996 Ford Explorer.
What you should do:
* Do not drive the vehicle: Driving with ATF in the power steering system will cause further damage and potentially lead to a complete power steering failure, making the vehicle dangerous to operate.
* Have it towed to a qualified mechanic: A professional mechanic has the tools and expertise to properly flush the power steering system and assess any damage.
* Expect repairs: Depending on the extent of the contamination, you'll likely need repairs beyond just a fluid flush. This could include replacing seals, hoses, or even the power steering pump. This is likely to be a costly repair.
This is a serious issue that requires immediate professional attention. Ignoring it will only lead to more expensive repairs in the future.
