Step By Step Guide For 7.3 Powerstroke Power Steering Pump Upgrade

Before performing a 7.3 power steering pump replacement, you have to know first where the power steering pump is located.

The power steering pump’s position differs for every vehicle.

Some have the steering fluid reservoir integrated with the pump, while other models have the reservoir tucked in a corner.

Generally, the power steering pump sits in front of the engine and other accessories under the hood.

The power steering pump and pulley is also attached onto a bracket for Ford pickup trucks with a 7.3 engine.

Noting these details down before wrenching out car parts will be helpful in preparing you for the procedure.

, car owners will drive their car to the mechanic for a 7.3 power steering pump replacement.

However, for you who prefers to do things DIY, we have a comprehensive step-by-step guide to help you perform a 7.3 power steering pump replacement by yourself.

STEP 1: Release The Tension off The Belt

The belt drives your car’s power steering pump, along with the rest of the car’s function.

To replace your power steering pump, you must remove the belt first. With a breaker bar, pull on the tensioner upwards.

This should take the tension off the belt, loosening it from the pulley. Unhook the belt.

STEP 2: Unhook The Alternator

The alternator sits atop the mounting bracket which holds the power steering pump and pulley.

There are 3 half-inch bolts keeping the alternator in place.

Unscrew the bolts and lift off the alternator, keeping it away from the bracket and the rest of the power steering pump.

Be careful not to snag on or unhook any of the wires connected to the alternator.

STEP 3. Remove The Lines Connecting to The Power Steering Pump

You should have a good view of the mounting bracket, the large pulley, and the power steering pump.

The reservoir could also be sitting atop the pump. Before unhooking the bracket, take out the lines connected with the power steering pump.

Be warned that steering fluid will drain out as you disconnect the lines.

Avoid the mess by readying a drain pan or bucket under your vehicle to catch the fluid. Unclasp the hose clamp from the pump.

Step 4. Dismount The Power Steering Pump

The mounting bracket holds together the large pulley and power steering pump. Some prefer to remove the pulley first.

However, we do not suggest this method because it is time-consuming.

For more efficiency, it is better to unhook the entire mounting bracket while the pulley and power steering pump are intact.

There are typically three bolts keeping the mounting bracket in place; two are in direct view, while the last one is hidden underneath. Take your time in unscrewing the bolts.

STEP 5. Unhook Some More Lines

Some lines run under the power steering pump, so be careful when dismounting the bracket. Disconnect the lines with a wrench.

STEP 6. Drain The Fluid

Fluid will drip from the power steering pump and disconnected lines. Let the fluid drain for a few minutes before proceeding to the next step.

STEP 7. Remove The Pulley

Transfer the mounting bracket to a flat workspace. At this point, you are ready to replace the old power steering pump.

Firstly, remove the pulley from the bracket  with a specially-designed tool called pulley removal tool.

Attach the locking nut onto the pulley. Insert the pulley removal tool, twisting it until it is snugly in place.

You will need two wrenches, working and wrenching against each other’s direction.

This can take some time, stopping only when the pulley is loose enough to remove.

STEP 8. Remove The Power Steering Pump

With the pulley detached, you now have direct access to the power steering pump.

Unscrew the three bolts attaching the pump to the bracket.

STEP 9. Replace With a Brand New Power Steering Pump

Putting in position the new power steering pump, attach it to the bracket with the bolts.

Make sure to screw the bolts in tightly to avoid issues caused by a loosened bolt.

STEP 10. Reinstall The Pulley

Reinstall the pulley using a pulley installation tool.

This tool works similarly with the pulley removal tool, except it keeps the pulley in place.

STEP 11. Reinstall The Bracket and The Disconnected Lines

With the brand new power steering pump installed, you are ready to pop the mounting bracket back into its place under the hood.

Reattach all disconnected lines, and bolt the bracket into place.

STEP 12. Reinstall The Alternator and Serpentine Belt

Bolt the alternator back to its original place on the bracket.

Run the belt back on to the pulley, tightening it as needed.

How To Choose The Ideal Power Steering Pump

Not all power steering pumps are made equal.

Differences in build, reservoir integration, and mere engine compatibility can make or break the deal in purchasing a replacement.

To help you decide which remanufactured power steering pump suits your engine, we listed down a few factors for you to consider:

01. Budget

How much are you willing to spend for a power steering pump replacement?

If you will be doing the replacement on your own, were you able to save money from labor costs?

A powerstroke power steering pump upgrade does not have to be expensive.

The price tag on the products do not determine their quality, after all.

However, having a flexible budget can broaden your choices for more durable products.

02. Integral Reservoir

One of the first questions a sales clerk or shopping website will ask you is whether the steering fluid reservoir for your power steering pump is integral to the pump, or remotely mounted.

Consider the location of your vehicle’s steering fluid reservoir.

For Ford pickup trucks such as the F-350, the steering fluid reservoir is integral to the power steering pump.

03. Steering Fluid Compatibility

The type of steering fluid you use will depend on your vehicle’s system and requirements.

However, it is good to consider which steering fluid is compatible with which power steering pump.

There are various steering fluid types available on the market.

These include automatic transmission fluid (ATF), synthetic power steering fluid, and mineral power steering fluid.

Take note of their differences so as not to ruin your brand new power steering pump with the incompatible fluid.

04. Engine Compatibility

This goes without saying, but the power steering pump replacement you are deciding to purchase must be compatible with your vehicle’s engine.

Does your engine run on diesel, or gas? Is it inline, or a v-engine layout? How many cylinders power your vehicle’s engine?

These matter for the smooth running of your power steering pump replacement.

For example, Ford F-250 and F-350 pickup trucks are some vehicles that run a 7.3 or PowerStroke engine.

Thus, these car models will need power steering pumps that are compatible with the 7.3 engine.

05. Durability

One of the reasons you are purchasing a power steering pump replacement is because the old power steering pump installed in your car broke down.

Rust, leaks, and loud squealing noises are signs of an eroding power steering pump.

Consider the quality of materials used for the product. Is it sturdy?

Is it friendly to the environment? How did it fare during performance tests?

A good power steering pump replacement should be long-lasting and at the same or better quality of stock models.

06. Warranty

Not all manufacturers would disclose warranty, but as a buyer, you have the right to request for warranty guidelines.

Before making a purchase, check the warranty of the power steering pump.

This will save you the hassle of returning the product or filing for a refund when issues arise during installation, or the performance does not meet your expectations.
