Typically, a van either uses hydraulic power steering, which relies on a fluid reservoir, or electric power steering, which does not use hydraulic fluid at all. To know which system you have, check your owner’s manual or look under the hood for a power steering fluid reservoir. If you don’t see a reservoir, your van is likely using electric assist.
Identify your steering system
Determining whether your van has hydraulic or electric power steering is the first step before checking fluid. The presence of a labeled reservoir usually indicates hydraulic PS, while an absence of a fluid reservoir or the presence of an electric motor near the steering rack points to electric PS.
Hydraulic vs electric indicators
Use this quick check to distinguish between systems without guessing:
- Hydraulic PS: There is a dedicated power steering fluid reservoir with min/max marks and a belt-driven pump.
- Electric PS: No hydraulic reservoir; steering assist is provided by an electric motor and sensors.
- Manual reference: If in doubt, consult the owner’s manual for the exact system type and fluid requirements.
Knowing the system type helps you determine whether you should check or top up fluid, or if the issue lies elsewhere in the steering system.
Signs your hydraulic power steering system may need fluid
If your van uses hydraulic steering, these signs often indicate low, dirty, or leaked fluid. They warrant a closer look or a top-up (using the correct fluid type) and potential inspection for leaks.
- Hard or stiff steering, especially at low speeds or when parking
- Whining, groaning, or squealing noises when turning the wheel
- Steering feel that is heavy, inconsistent, or less responsive
- Visible leaks under the front of the vehicle or around the PS pump and hoses
- Fluid level below the minimum mark on the reservoir or a dipstick reading
- Fluid that looks dark, dirty, or burnt in the reservoir
If you notice one or more of these signs, check the fluid level and inspect for leaks. Running the system with low fluid can damage the pump and steering components.
How to check and add hydraulic power steering fluid
If your van has hydraulic power steering, follow these steps to safely check the level, add the correct fluid, and ensure proper operation. Always use the fluid type specified by your manufacturer and avoid mixing fluids.
- Park on a level surface, engine off, and engage the parking brake. Some manuals recommend waiting a few minutes for the fluid to settle.
- Open the hood and locate the power steering reservoir. The cap is typically labeled and may feature a steering-wheel icon or the words “Power Steering.”
- Check the fluid level against the min/max marks on the reservoir or dipstick if present. If the level is below the minimum, plan a top-up.
- Verify the required fluid type in the owner’s manual or on the reservoir cap. Common options include standard power steering fluid or a specific ATF specification. Do not mix fluids.
- With the engine off, slowly add the recommended fluid until it reaches the max line. Wipe up any spills.
- Start the engine and turn the steering wheel from lock to lock several times to circulate the new fluid. Check for smooth operation and look for leaks.
- If the level drops again quickly or you notice leaks, stop and have the system inspected by a qualified mechanic.
Note: Some vans have sealed hydraulic systems that are not designed to be topped up by owners. If you repeatedly need to add fluid or cannot locate a reservoir, seek professional service to check for leaks or a failing pump.
What if your van has electric power steering?
Electric power steering does not use hydraulic fluid. If you have EPS, steering issues are usually related to the electric motor, sensors, belt tension, or the control module rather than fluid loss. In such cases, refer to the owner’s manual and consider a diagnostic check if you notice hard steering, abnormal noises, or warning lights.
When to seek professional help
Persistent low fluid readings, ongoing leaks, strange noises, or steering that remains heavy after any top-up are red flags. A professional mechanic can diagnose leaks, pump wear, rack and pinion issues, or faults in an electric steering system.
Summary
In short, identify whether your van uses hydraulic or electric steering. Hydraulic systems require the correct power steering fluid and regular checks for level, cleanliness, and leaks; electric systems do not use fluid and require diagnosis of non-fluid-related steering components when problems arise. Regular maintenance, prompt attention to unusual steering behavior, and consulting your owner’s manual will help keep your van steering safe and reliable.
Does Grease Monkey change power steering fluid?
Grease Monkey provides fluid exchange services for critical vehicle systems, including engine oil, transmission fluid, coolant (radiator fluid), brake fluid, and power steering fluid.
How expensive is it to fix power steering?
On average, replacing your power steering pump can cost between $500 and $900, but it's essential to avoid more serious damage to the power steering system. Replacing the pump yourself can save you about $300 and significantly lower the total cost of this repair.
Can you just add more power steering fluid?
If the dipstick or reservoir level is between “MIN” and “MAX,” you don't need to add fluid. If the fluid is below the “MIN” line, remove the cap (or leave the dipstick out) and add power steering fluid in small amounts, checking the level after each time. Don't fill it above the “MAX” line.
What are symptoms of power steering fluid being low?
Insufficient fluid prevents the system from working properly, which you'll often feel as a stubborn steering wheel. Steering Whine: If you hear a loud whining or screeching noise coming from under the hood when you steer, particularly if you turn the wheel as far as it goes, it's likely due to low power steering fluid.
