Cadillac DeVille Power Steering Pump Guide (1980-1987)
Everything you need to know before replacing the power steering pump on your 1980-1987 Cadillac DeVille.
- A whining noise that changes with engine speed is the number one sign of a failing power steering pump.
- You will need a specific pulley puller/installer tool to swap the pulley from the old pump to the new one.
- Aftermarket brand quality is mixed; flushing the system with new fluid is critical to the new pump's lifespan.
- Driving without power steering is possible but very difficult and not recommended due to the increased effort required to steer.
Is Your DeVille's Power Steering Pump Failing?
A failing power steering pump gives clear warning signs. Ignoring them can lead to a complete loss of power assist, making the car hard to control. Listen for these symptoms, especially on a classic luxury car like the DeVille where smooth operation is key.
Common Failure Symptoms:
🎬 Watch: How to diagnose a bad power steering pump- Whining or Groaning Noises: The most common sign is a whining noise that gets louder when you turn the steering wheel or as engine RPMs increase. This is often caused by low fluid or a worn-out pump.
- Stiff Steering Wheel: If turning the wheel suddenly requires a lot of muscle, especially when parking or driving slowly, the pump is likely not providing enough pressure.
- Fluid Leaks: Finding reddish or light brown puddles under the front of your car is a sign of a power steering fluid leak. Low fluid will damage the pump over time.
- Slow or Jerky Response: If the steering feels like it's lagging, vibrating, or responding unevenly, it could be due to a failing pump causing inconsistent pressure.
Known Issues for this Generation
While no direct recalls exist for the power steering pump on 1980-1987 models, the National Highway Traffic Safety Administration (NHTSA) investigated the 1986 DeVille for issues with the ABS brake system. This investigation noted that the power assist functions for braking could be affected, which are related to the car's hydraulic systems. Always ensure your entire hydraulic system, including power steering, is in good working order.
Choosing the Right Aftermarket Pump: Cardone vs. BBB Industries
For a 1980-1987 DeVille, new OEM parts are scarce. Your main choices will be new or remanufactured aftermarket parts from brands like Cardone and BBB Industries.
Based on owner feedback and mechanic discussions in online forums, aftermarket quality can be inconsistent. Many users have reported premature failures with remanufactured pumps from various brands. Some mechanics express a strong preference for finding a used, low-mileage OEM pump from a junkyard over a remanufactured aftermarket part.
- Cardone: This brand is widely available. However, it has a mixed reputation online, with some users reporting issues with parts failing shortly after installation. Cardone often provides a good warranty, which can be a factor in your decision.
- BBB Industries: This is another common brand. Like Cardone, reviews are mixed. Some sources suggest they may be a slightly better alternative, while others have experienced early failures. One forum post mentioned that Cardone may own BBB Industries.

Frequently Asked Questions (FAQ)
Is replacing the power steering pump a DIY job?
Yes, it is feasible for an experienced DIY mechanic. However, it requires a special tool: a power steering pump pulley puller and installer kit. You cannot simply hammer the pulley onto the new pump. Access can be tight, and you will need a good set of wrenches, including potentially flare nut wrenches for the fluid lines. The job involves draining fluid, removing the drive belt, unbolting the pump, swapping the pulley, 🎬 See how to remove and install a press-fit pulley and reinstalling everything.
Do I need to bleed the system after replacing the pump?
Yes, this is a critical step. After installing the new pump and filling the reservoir, you must bleed the air out of the system. To do this, with the engine off, turn the steering wheel from lock to lock several times. Then, start the engine and repeat the process, topping off the fluid as needed until the whining noise stops 🎬 Watch this guide on bleeding a GM power steering system and steering is smooth.
What type of power steering fluid should I use?
Always check your owner's manual or a reliable service manual for the correct fluid specification for your specific year and engine. Using the wrong type of fluid can damage the pump and other steering components.
Does the new pump come with a pulley and reservoir?
It depends on the specific part you buy. Many aftermarket pumps for this vehicle do NOT include the pulley or the reservoir. You will need to carefully remove the pulley from your old pump and install it on the new one. If the reservoir is separate, you may need to transfer it as well.
