Power Steering Pump on Your 1973-1977 Oldsmobile Cutlass: A Replacement Guide
Restore that classic, one-finger steering feel by addressing a weak or failing power steering pump.
- Symptoms of failure include whining noises, stiff steering, and fluid leaks.
- A special pulley puller/installer tool is required for replacement; it can often be rented for free.
- Always flush the entire system of old fluid and contaminants before installing a new pump to prevent damage.
- On a car this old, check for cracked and leaking hoses first, as they are a common and simple point of failure.
Is Your Cutlass Power Steering Pump Failing?
On a classic car like the 1973-1977 Oldsmobile Cutlass, parts often fail from age as much as mileage. The power steering pump is no exception. Look out for these common symptoms that mean your pump is ready for replacement.
- Whining or Groaning Noises: This is the most common sign. You may hear a whining sound that gets louder when you turn the wheel or rev the engine. This is often caused by low fluid or a worn-out pump.
- Stiff Steering: If turning the wheel suddenly feels like a workout, the pump is likely not producing enough pressure. This can be dangerous, especially at low speeds.
- Fluid Leaks: Reddish-brown fluid puddles under the front of your car are a tell-tale sign of a leak. While old hoses are a common cause, the pump itself can leak from its seals or housing.
- Slow or Jerky Steering: If the steering wheel feels like it's slipping or catching, it can be a sign of inconsistent pressure from a failing pump.
Pro Tip: Check Your Hoses First
Before you blame the pump, clean the pump and hoses thoroughly and check again for the source of any leak. On a 50-year-old car, rubber power steering hoses can become brittle, cracked, and leak. Sometimes, a new hose is all you need.
Choosing the Right Aftermarket Pump
For a vehicle from the 1970s, finding a brand-new, original GM power steering pump is nearly impossible. Your realistic options are new aftermarket or remanufactured aftermarket parts. For this specific part, most "new aftermarket" options are actually remanufactured.
- Remanufactured Pumps (BBB Industries, etc.): This is the most common and practical choice. Companies like BBB Industries take original pump cores, completely disassemble them, clean all components, and replace all wear-and-tear parts like seals, O-rings, and bearings with new OE-equivalent parts. The unit is then tested to ensure it performs correctly. While quality can sometimes be inconsistent with any remanufactured part, choosing a reputable brand with a good warranty is key.
- Used OEM: A pump from a junkyard is a low-cost option, but it's a gamble. You don't know its history, and it could fail shortly after installation.
Important: New vs. Remanufactured
The term "new aftermarket" can be confusing. For many classic car parts like power steering pumps, the main aftermarket supply consists of remanufactured units. These are not just cleaned-up used parts; they are rebuilt to factory specifications with new internal components and come with a warranty. BBB Industries is a well-known remanufacturer.

Frequently Asked Questions (FAQ)
Can I replace the power steering pump myself?
Yes, this is a very DIY-friendly job for someone with basic mechanical skills. The main special tool you will need is a power steering pump pulley puller and installer. Most auto parts stores offer this as a free loaner tool. You will also need a set of basic hand tools.
What kind of power steering fluid should I use in my Cutlass?
For a 1970s GM vehicle, standard power steering fluid is acceptable. Some owners also use Automatic Transmission Fluid (ATF) like DEXRON/MERCON, which was common practice at the time. To be safe, a universal power steering fluid that is compatible with older domestic vehicles is a great choice. Always flush the old fluid out completely when installing a new pump.
Are there any recalls for the 1973-1977 Cutlass power steering pump?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any safety recalls specifically for the power steering pump on this vehicle. Failures are typically due to normal age and wear.
How do I bleed the air out of the system after installing a new pump?
After installing the new pump and filling the reservoir, leave the engine OFF. Turn the steering wheel fully from lock to lock about 10 times to work the fluid through the system and push air into the reservoir. Top off the fluid level. Then, start the engine and repeat the lock-to-lock turning. Check the fluid one last time and inspect for leaks.
