1. Immediate Action: Have the vehicle towed to a qualified mechanic or repair shop. Do not attempt to flush the system yourself unless you have significant experience working on cars and have the proper tools and safety equipment (including eye protection and gloves). Driving with antifreeze in the power steering system could lead to complete power steering failure, making the car difficult or impossible to steer, and could damage the pump beyond repair.
2. Explain the Situation: Clearly explain to the mechanic that antifreeze was mistakenly added to the power steering reservoir.
3. Expect Extensive Repairs: The mechanic will likely need to:
* Completely flush the power steering system: This involves removing all the contaminated fluid and replacing it with fresh power steering fluid. This is a more involved process than a simple fluid change.
* Inspect the power steering pump: Antifreeze can damage the pump seals and internal components. The pump may need to be replaced.
* Inspect the power steering rack and pinion (or other steering components): Antifreeze can cause corrosion and damage to other parts of the system.
* Inspect the power steering lines and hoses: Check for damage or leaks. They may need replacing.
4. Cost of Repairs: Be prepared for significant repair costs. The damage could range from a simple fluid flush to a complete power steering system overhaul.
In short: Towing to a mechanic is the only safe and responsible course of action. Trying to fix this yourself without proper knowledge and tools could worsen the damage and be dangerous.
