Adding power steering fluid is a straightforward maintenance task you can do yourself in about 10 minutes. The core steps are: locate the reservoir, check the fluid level, and add the correct type of fluid until it reaches the "Full" or "Max" line on the dipstick. Always check your owner's manual for the specific fluid type recommended for your vehicle, as using the wrong kind can damage the power steering system.
First, ensure the engine is off and the car is parked on a level surface. Pop the hood and locate the power steering fluid reservoir. It's usually on the passenger side of the engine bay, with a cap that has a steering wheel icon. Wipe the reservoir and cap clean with a rag to prevent dirt from falling in when you open it.
Unscrew the cap; some have a built-in dipstick. Check the fluid level against the "Cold" or "Hot" markings. If it's below the "Min" or "Add" line, you need to add fluid. Using a funnel to avoid spills, slowly pour small amounts of the correct fluid—common types include Dexron III ATF or specific synthetic power steering fluids—into the reservoir.
Recheck the level frequently; it's easy to overfill. The goal is to get the fluid to the "Full" line. Once done, securely screw the cap back on. Start the engine and turn the steering wheel lock-to-lock a couple of times to circulate the new fluid. Check for leaks around the reservoir and hoses. A sudden need for frequent fluid top-offs often indicates a leak that should be inspected by a mechanic.
