How to Check Power Steering Fluid (and When to Change It)
Published: March 18, 2025 | By 907 Synthetics – Authorized AMSOIL Dealer in Alaska
Why Power Steering Fluid Matters – Especially in Alaska
Power steering makes driving effortless and safe, especially during Alaska’s long winters with icy roads and heavy snow. Over time, power steering fluid breaks down, gets contaminated, and loses its ability to protect the pump, hoses, and steering rack.
Neglecting it can lead to annoying pump whine, stiff steering, leaks, or even expensive pump failure. The good news? Checking and changing power steering fluid is straightforward and one of the smartest maintenance tasks you can do.
How to Check Power Steering Fluid – Step by Step
Checking your power steering fluid takes just a few minutes and should be done regularly — every time you check your oil or before long trips.
- Locate the Reservoir
It’s usually a small, clear plastic container with a black cap, often near the firewall or one of the front wheels. Many reservoirs have “MIN” and “MAX” marks on the outside. - Check the Level (Cold Engine)
With the engine off and cold, the fluid should be between the MIN and MAX marks. Some vehicles have a dipstick on the cap. - Use the Dipstick (If Equipped)
Remove the cap, wipe the dipstick clean with a rag, reinsert it fully, then remove it again to read the level. Pay attention to “Cold” vs “Hot” markings. - Top Off if Needed
Use the correct type of fluid for your vehicle (check your owner’s manual). Never overfill.
When Should You Change Power Steering Fluid?
Many manufacturers recommend changing power steering fluid every 30,000 to 60,000 miles or every 3–5 years. In Alaska’s harsh conditions — extreme cold, temperature swings, and lots of short trips — changing it more frequently is smart.
Change it immediately if you notice:
- Dark, dirty, or burnt-smelling fluid
- Whining or groaning from the power steering pump
- Stiff or jerky steering
- Fluid leaks under the vehicle
Old fluid accumulates wear particles, moisture, and sludge, which accelerates wear on expensive components.
Choose the Right Fluid: AMSOIL Synthetic Power Steering Fluid
Standard power steering fluid breaks down quickly under heat and cold. AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is a superior choice because it:
- Provides excellent protection in extreme cold (critical for Alaska winters)
- Resists oxidation and thermal breakdown
- Reduces friction and pump noise
- Helps keep seals soft to prevent leaks
- Works in a wide range of vehicles (Ford, GM, Chrysler, Toyota, Honda, European models, and more)
Easy Methods to Change Power Steering Fluid
1. The Simple “Poor Man’s” Flush (Recommended for Most People)
This method is clean, easy, and very effective:
- Use a fluid extraction pump or turkey baster to remove old fluid from the reservoir.
- Refill with fresh AMSOIL Synthetic Power Steering Fluid.
- Start the engine and turn the steering wheel lock-to-lock several times.
- Repeat the process 3–4 times until the fluid runs clean.
2. Full System Flush
For maximum results, disconnect the return hose and flush the system with a helper. This removes more old fluid but is messier and more technical.
Pro Tip: AMSOIL’s Fluid Extraction Pump makes this job quick and clean.
