Pontiac Firebird Power Steering Pump Guide: 1977-1981
Everything you need to know before replacing the power steering pump on your second-generation Firebird.
- Common failure signs are whining noises when turning, a stiff steering wheel, and fluid leaks.
- Aftermarket remanufactured brands like Cardone have very mixed quality reviews; proceed with caution.
- Rebuilding your original GM pump is often a reliable alternative to buying a remanufactured unit.
- Properly bleeding all air from the system after installation is critical for the new pump's lifespan.
Is Your Firebird's Power Steering Pump Failing?
A bad power steering pump on a classic Firebird usually gives you plenty of warning. The system is simple, but when the pump wears out, you'll notice it. The most common signs are noises, leaks, and a change in how the steering feels.
Common Failure Symptoms
- Whining or Groaning Noises: This is the classic sign of a failing pump. You'll hear a whining or groaning sound when you turn the steering wheel, especially in a parking lot. This noise often means the fluid is low or the pump is struggling to create pressure.
- Stiff Steering: If turning the wheel suddenly requires a lot of muscle, your pump isn't providing enough hydraulic assist. This can be intermittent at first but will get worse.
- Fluid Leaks: Power steering fluid is typically reddish or reddish-brown. If you see puddles of this color fluid under the front of your car, the pump or its hoses are likely leaking.
- Metal Flakes in Fluid: If you check your power steering fluid and see shiny metal specks, it's a critical sign that the pump is grinding itself apart internally. This contamination can damage the entire steering system.
Don't Ignore a Failing Pump
Continuing to drive with a failing pump can cause more damage. Metal shavings from a dying pump can circulate through the system and ruin the steering gear, leading to a much more expensive repair. If the pump seizes, it can snap the drive belt, which may also run other accessories on your engine.
Choosing a New Aftermarket Power Steering Pump
For a 1977-1981 Firebird, finding a brand-new original GM part is nearly impossible. Your main options are new aftermarket pumps or remanufactured pumps. The original Saginaw-style pumps on these cars were very durable, so the quality of the replacement is important.
Aftermarket Brand Quality: Cardone vs. BBB Industries
When shopping for an aftermarket pump, you will likely encounter brands like Cardone and BBB Industries. It is important to be aware of their reputation among classic car owners.
- Cardone: This is a widely available brand. While some users have had success, Cardone's remanufactured parts have a mixed reputation for quality control. Forum discussions frequently mention receiving pumps that were defective out of the box, leaked soon after installation, or had fitment issues. Experienced mechanics sometimes report having to try multiple units to find a good one.
- BBB Industries: There is less specific feedback for this brand on Firebirds. Some users report positive experiences. However, like Cardone, they are a remanufacturer, and some forum posts show concerns about the quality of their rebuilding process. Some sources suggest a business relationship between Cardone and BBB, with parts sometimes appearing similar.
Pro Tip: Consider Rebuilding Your Original Pump
If your original pump is just leaking but still works, rebuilding it can be a great option. The original GM pump housings are often higher quality than aftermarket replacements. Rebuild kits with new seals are available and affordable. This path requires more mechanical skill but often results in a very reliable repair.

Frequently Asked Questions
Do I need a special tool to replace the pump?
Yes. The pulley on these pumps is press-fit onto the shaft. You will need a specific power steering pulley puller and installer tool to safely remove the pulley from your old pump and install it on the new one. Most auto parts stores offer these as loaner tools.
Do I have to replace the hoses at the same time?
It is highly recommended. Your Firebird's hoses are over 40 years old. Old, brittle hoses can fail under the pressure of a new pump. Replacing the high-pressure and return hoses is a smart investment to prevent future leaks.
What kind of power steering fluid should I use?
Always use a high-quality, standard power steering fluid. Check the bottle to ensure it's compatible with GM vehicles of this era. Do not use automatic transmission fluid (ATF) unless specifically called for, which is uncommon for this model.
What is the most important step of the installation?
Bleeding the system. After installing the new pump and filling it with fluid, you must get all the air out of the lines. To do this, with the engine off and front wheels in the air, slowly turn the steering wheel from full lock to full lock about 10-15 times. Then, start the engine and repeat. Air left in the system will cause whining noises and can damage the new pump.
Were there any recalls for the 1977-1981 Firebird power steering pump?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no safety recalls specifically for the power steering pump or system on the 1977-1981 Pontiac Firebird.
Technical Specifications
The system uses a belt-driven Saginaw-style hydraulic pump. A specific power steering pulley puller/installer tool is required for service. The system must be bled of air after replacement.
