It starts with a whine. At first, you ignore it, thinking maybe the cold morning air is making your car complain. But soon, that sound grows louder. Then you notice steering feels heavy when turning into a parking lot. Annoying, right? That’s your power steering pump crying out for help.
Many owners of the 2011 Chevy Traverse face this exact problem. And yes, fixing it sounds scary. But here’s the truth—it’s not impossible. With some patience, a few tools, and simple steps, you can replace the pump yourself.
6 Steps to Change Power Steering Pump on 2011 Traverse
Get the Tools and Area Ready
Before touching the pump, get everything ready. Having tools on hand keeps you from running back and forth. You’ll need wrenches, sockets, a pulley removal tool, screwdrivers, new fluid, and of course, the new pump. A drain pan is a must because power steering fluid loves to drip everywhere. Gloves and safety glasses make the work safer and less messy.
Choose a flat, open spot to work. Your driveway is fine as long as it’s stable. Good light helps too, so either work in daylight or use a bright shop light. Parking on a slope is risky because you’ll need to jack the car later. Make sure you set the parking brake firmly before crawling under.
It helps to clear out distractions before you begin. This job takes time, and rushing can lead to mistakes. Keep kids and pets away from the car, because spilled fluid is slippery and not safe. Laying down cardboard under the car keeps your driveway clean from drips.
Finally, double-check the new pump before you start. Compare it with the old one in size and fittings. If it looks different, stop and return it. Once you pull the old pump, you don’t want surprises that stall your repair halfway.
- Gather wrenches, sockets, pulley tool, screwdrivers, fluid, pump, and drain pan
- Wear gloves and glasses for safety
- Work on a flat surface with good light
- Keep pets and kids away for safety
- Check the new pump matches the old one
Drain the Power Steering Fluid
The next part is draining the old fluid. Power steering fluid is thin, slick, and loves to spread if you’re not careful. Place the drain pan under the lines before loosening anything. Wipe down the pump so you can see where the hoses attach. Most times, there’s a low-pressure return line that’s easiest to remove first.
Use a wrench or pliers to loosen the clamp. Twist the hose gently before pulling it off. Fluid will start running out quickly, so be ready. Let it drain fully into the pan. If it splashes, grab rags and clean it right away because it’s slippery. While it drains, check the hose for cracks or swelling. If it looks worn, replace it.
After the fluid drains, you may still have some left inside the pump. Turn the steering wheel back and forth with the engine off. This pushes out extra fluid through the open hose. Be patient here, because leftover fluid can cause mess later when you remove the pump.
Don’t forget about the high-pressure line too. This one uses a fitting that requires a wrench. Place the pan under it before loosening. It might be tighter than you expect, so use steady pressure. Once both hoses are free, cap them with tape or plugs to keep dirt out.
- Place a pan under pump before loosening lines
- Remove return hose first and drain fluid
- Turn steering wheel to push more fluid out
- Remove high-pressure line carefully
- Plug hoses to block dirt
Remove the Old Pump
Now the pump itself comes out. First, disconnect the serpentine belt. Use a wrench on the tensioner pulley and push to release tension. Slip the belt off and move it aside. Remember the belt routing or snap a picture, because you’ll need it later.
Next, locate the bolts holding the pump bracket. Usually, there are three or four bolts. Spray them with a little penetrating oil if they look rusty. A socket wrench works best to loosen them. Once loose, hold the pump because it may shift or drop slightly.
The pulley is attached to the pump and needs special handling. Use the pulley removal tool to pull it off the shaft. Don’t try prying it with a screwdriver—it damages the pulley. Take your time, because this step is often stubborn. Once the pulley is free, set it aside somewhere clean.
Now lift the pump out carefully. Watch for any hidden bolts or wires. Some models may have a small bracket or sensor attached. Check before pulling too hard. Once free, set the pump on the ground and compare it with your new one. Size, bolt holes, and hose fittings must look the same.
- Release serpentine belt by moving tensioner
- Remove pump mounting bolts with socket
- Use proper tool to pull pulley off
- Lift pump carefully and check for extra parts
- Compare old and new pump for exact match
Install the New Pump
With the old pump out, get the new one ready. First, press the pulley onto the new pump. Use the pulley installer tool to do this evenly. Do not hammer it, because that bends the pulley. Keep turning the tool until the pulley sits flush with the shaft.
Set the pump in place where the old one sat. Line up the bolt holes and hand-thread the bolts first. This keeps the pump straight. Once all bolts are started, tighten them evenly with the socket. Don’t over-tighten, just snug them down. A wobbly pump can cause belt noise later.
Next, reattach the high-pressure line. Thread it by hand to avoid cross-threading. Once snug, tighten with the wrench. Then slide the return hose back on and clamp it. Make sure both lines are secure, because leaks here cause steering trouble.
Now, route the serpentine belt back on. Use your picture or the belt diagram under the hood. Slip the belt over each pulley and release the tensioner to lock it in place. Check the belt is seated in every groove. A misaligned belt makes loud squeals.
- Press pulley onto new pump with installer tool
- Bolt pump into place evenly
- Reconnect high-pressure and return lines
- Reinstall serpentine belt correctly
- Double-check belt alignment and hose clamps
Refill and Bleed the System
With everything hooked up, it’s time to refill. Pour new power steering fluid into the reservoir. Fill it to the correct level marked on the dipstick. Don’t overfill, because fluid expands when warm.
Before starting the engine, turn the steering wheel left and right slowly. This pushes fluid into the pump and hoses. You may see bubbles in the reservoir—that’s normal. Keep adding fluid until the level stays steady.
Now start the engine. Again, turn the wheel back and forth. Listen for whining or groaning sounds. If the pump is noisy, there’s still air in the system. Keep turning until bubbles stop forming in the reservoir. It can take a few minutes.
Check the fluid level one more time with the engine running. Add fluid if needed. Wipe around the pump and hoses to check for leaks. If you see drips, tighten the fittings. A quiet pump with smooth steering means the job is done right.
- Fill reservoir with new fluid
- Turn wheel with engine off to push fluid in
- Start engine and turn wheel to remove air
- Watch for bubbles and noise until smooth
- Check fluid level and leaks carefully
Test Drive and Check Again
The final part is testing. Take the Traverse for a short drive around the block. Make slow turns and sharp turns. Notice if the steering feels smooth and light. Any whining noise means air is still inside. If so, repeat the bleeding process.
After driving, park and open the hood. Check the fluid level again. Sometimes it drops after the first drive. Add more if needed, but never overfill. Look under the car for leaks, especially near the hoses and pump. Wipe spots clean and check again after a few minutes.
Keep an eye on the pump for the next few days. Fluid levels can shift as trapped air escapes. It’s normal to top off once or twice. But if the level keeps dropping, check for leaks again. A steady level means the system is sealed well.
Enjoy the smooth steering now. Replacing the pump may have felt big, but you handled it. With steady turns and no whining, your Traverse is ready for many more miles.
- Drive and test steering feel
- Recheck fluid level after drive
- Watch for leaks under car
- Top off fluid if level drops
- Monitor pump over next days
Changing the power steering pump on a 2011 Traverse takes effort but is very possible. With patience, tools, and careful checks, the job brings back smooth steering. Staying calm, working step by step, and checking leaks makes the whole repair safe and successful.

Do you need to replace hoses when changing the pump?
Sometimes yes, sometimes no. Hoses in a 2011 Traverse are made of rubber and metal. Over time, rubber breaks down from heat and fluid. Cracks, swelling, or leaks are signs they should be replaced. Even if they look okay, old hoses can collapse inside, blocking flow. That makes steering stiff and noisy.
When changing the pump, it’s smart to check hoses carefully. If they feel soft, spongy, or brittle, replace them now. Waiting means you may need to drain fluid again later, which wastes time and money. Plus, a bad hose can make the new pump fail early.
Replacing hoses is not very expensive compared to the pump. The peace of mind is worth it. Many DIY mechanics choose to change them together. That way, the system is fresh and reliable. If hoses look fine and you’re short on budget, you can reuse them. But keep checking them often.
If you decide to replace, always use correct size hoses for the Traverse. Aftermarket ones may kink or leak. OEM parts or high-quality replacements fit better. Install new clamps too, because old clamps sometimes don’t grip well after years of use.
In short, hoses may not always need replacing, but it’s a wise choice if they show age. Fresh hoses protect the new pump and keep your steering smooth. Think of it like new shoes with new socks—they work better together.
Do power steering pumps fail suddenly on a 2011 Traverse?
Most of the time, failure comes slowly. You’ll hear whining or groaning noises first. Then the steering feels heavy, especially at low speeds. Sometimes fluid leaks under the car, leaving oily spots. These are early signs the pump is wearing out.
But sometimes pumps can fail quickly. A seal may burst, or the shaft bearing may lock up. When this happens, steering gets very stiff right away. It feels like wrestling the wheel just to turn into a driveway. That’s not safe, especially in traffic or bad weather.
Heat, old fluid, and wear cause pumps to fail faster. If fluid is never changed, it loses lubrication. That makes the pump work harder until it gives out. Keeping fluid clean extends pump life a lot.
For most Traverse owners, problems build up over weeks or months. This gives enough warning to fix before total failure. Still, ignoring early signs is risky. One day, you may turn the wheel and feel it lock hard. That’s the sudden failure nobody wants.
The best way to avoid surprise breakdowns is to check fluid often. Listen for noises and pay attention to steering feel. Early care keeps you from being stuck with a pump that dies without warning.
Can you drive a 2011 Traverse with a bad power steering pump?
Technically yes, but it’s not smart. When the pump fails, steering becomes very heavy. Parking lots, sharp turns, and slow maneuvers feel like lifting weights. On the highway, it may feel okay, but in an emergency turn, the heavy wheel can be dangerous.
A bad pump also risks more damage. When it seizes, the serpentine belt may snap or slip. That belt powers other parts like the alternator and air conditioning. If the belt goes, you could lose charging power and cooling at once. That leaves you stranded.
Driving with a bad pump also means leaking fluid can drip onto hot engine parts. That may cause smoke or strong smells. In rare cases, it could even catch fire. So, it’s not just steering you should worry about.
Some people drive short distances with a failing pump, like to a shop. That can work if you’re careful. But forcing steering too much can hurt your arms and put stress on the rack. The longer you drive, the worse it gets.
The smart choice is not to keep driving. Replace the pump as soon as you can. Even if it feels drivable, the risks are high. Safe steering is worth the repair right away.
Do you need to bleed the power steering system after replacing the pump?
Yes, always. Air trapped inside the system makes the pump noisy and steering jerky. Without bleeding, bubbles compress and make the wheel feel jumpy. That’s frustrating and unsafe.
Bleeding is simple but takes patience. After refilling fluid, you turn the wheel back and forth slowly. This pushes air out through the reservoir. You’ll see bubbles rise in the fluid. Keep adding until the level stays steady.
If you skip bleeding, the pump can fail early. Air inside reduces lubrication and heats the pump. That burns seals and shortens its life. So, never rush this step.
Sometimes, bleeding takes more than one round. After the first drive, check again. If you hear whining, bleed more. It’s normal for bubbles to hide in hoses and come out later. Keep at it until noise stops.
In short, bleeding is not optional. It’s the final step that makes the repair complete. A quiet pump and smooth steering show you did it right.
Frequently Asked Questions (FAQs)
Is it hard to replace the power steering pump on a Traverse?
It can feel tricky, but it’s not impossible. The hardest part is dealing with the pulley and draining fluid without mess. With the right tools and clear instructions, most people can handle it. Taking time and staying patient makes it much easier.
Can I change the power steering pump without special tools?
It’s better not to. The pulley removal and install tool is needed for this job. Without it, you risk breaking the pulley or bending parts. Some auto stores rent tools for free, which saves money and avoids trouble.
Do I need to replace the fluid reservoir too?
Usually no, unless it’s cracked or leaking. But cleaning the reservoir is smart. Dirt inside can mix with new fluid and damage the new pump. Flushing it well keeps the system clean and strong.
Is it safe to buy a used power steering pump?
It’s risky. A used pump may fail sooner, and you’ll end up repeating the work. New or remanufactured pumps come with a warranty, making them a safer choice. Saving a little money on a used part can cost more later.
Can I flush the system without replacing the pump?
Yes, flushing helps if fluid is dirty but the pump is still good. Fresh fluid keeps the pump healthy. However, if the pump already whines or leaks, a flush won’t fix it. At that point, replacement is needed.
Do I have to align the pulley after installing it?
Yes, alignment is very important. The pulley must sit flush on the pump shaft. If it sticks out or sits too far in, the belt won’t line up. That causes squeals, wear, and even belt damage.
Is it normal for the pump to be noisy after replacement?
At first, yes. A little noise happens until all air is bled out. If noise stays after bleeding, check hoses and fittings for leaks. A properly installed pump runs quiet and smooth.
Can I use any type of power steering fluid?
No, always use the fluid type listed in your owner’s manual. The 2011 Traverse needs specific fluid. Using the wrong kind can damage seals and shorten pump life.
