- This guide is for the front-wheel-drive 1988-1990 Pontiac LeMans, not earlier models.
- Confirm your engine size (1.6L or 2.0L) before ordering, as they use different pumps.
- Symptoms like whining noises, stiff steering, or red fluid leaks point to a failing pump.
- Always flush the power steering system and inspect hoses when replacing the pump to prevent damage to the new part.
A Note on Vehicle Years
If you're shopping for a 1983-1990 Pontiac LeMans, it's important to know that this range covers two very different cars. The LeMans name was used on a rear-wheel-drive mid-size car until 1981 in the United States. The name was brought back for the 1988-1993 model years on a completely different vehicle: a front-wheel-drive subcompact based on the Daewoo LeMans. This guide focuses specifically on the 1988-1990 front-wheel-drive Pontiac LeMans.
Symptoms of a Failing Power Steering Pump
A bad power steering pump gives clear warning signs. Ignoring them can lead to a complete loss of steering assist, making the car difficult to control.
- Whining or Groaning Noises: A common first symptom is a whining or groaning sound that gets louder when you turn the steering wheel. This is often caused by low fluid or air in the system, but can also indicate the pump itself is wearing out.
- Stiff Steering Wheel: If turning the wheel suddenly requires a lot of muscle, especially when parking or driving slowly, the pump is likely failing to provide enough hydraulic pressure.
- Fluid Leaks: Power steering fluid is typically red or reddish-brown. If you see puddles of this color fluid under the front of your car, inspect the pump and hoses immediately. While a leak can come from a hose, the pump seals are a common failure point.
- Slow Steering Response: A noticeable delay or hesitation between when you turn the wheel and when the car responds can be a sign of a failing pump.
Check Your Engine Size!
The 1988-1990 Pontiac LeMans was available with different engines, primarily a 1.6L and a 2.0L four-cylinder. These engines use different power steering pumps. The pump for the 2.0L engine has an OEM part number of 26008258. Always verify your vehicle's engine before ordering a replacement part to ensure you get the correct fit.
Choosing a New Aftermarket Pump
For a vehicle like the 1988-1990 LeMans, finding a brand new original equipment (OEM) pump from GM is highly unlikely. The most common and available option is an aftermarket part.
- OEM Parts: Genuine GM parts for this vehicle are generally no longer in production. Finding a new-old-stock (NOS) part would be extremely rare and expensive. A used OEM pump from a junkyard is an option, but its remaining lifespan is unknown.
- Aftermarket Parts (BBB Industries): New aftermarket pumps are the most practical choice. BBB Industries is a common brand available for this vehicle. Online reviews and forum discussions about BBB's remanufactured power steering components are mixed. Some users have had good experiences, while others report issues with quality and longevity, sometimes receiving parts that fail prematurely. Since this is often the only brand available, it is the go-to choice, but be aware that quality can be inconsistent.
When replacing your power steering pump, it is critical to flush the old, contaminated fluid out of the system. Debris from the old failing pump can quickly damage the new one. Also, inspect the power steering hoses for cracks, brittleness, or leaks and replace them at the same time if they are in poor condition.
Power Steering Pump Replacement Cost

| Remanufactured Aftermarket Pump | $180 - $200 |
| Shop Labor | $200 - $500 |

Frequently Asked Questions
Are there any recalls for the 1988-1990 LeMans power steering pump?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls specifically for the power steering system on the 1988, 1989, or 1990 Pontiac LeMans.
Can I replace the power steering pump myself?
Yes, for a mechanically inclined person, this is a manageable DIY job. The pump is typically located at the front of the engine and is driven by a belt. The job usually takes between one and three hours. You may need a special pulley remover tool, which can often be rented from auto parts stores.
What kind of fluid does the Pontiac LeMans use?
Always consult your owner's manual for the specific type of power steering fluid required. Using the wrong fluid can damage the system. If you are unsure, a standard power steering fluid from a reputable brand is generally a safe choice for vehicles of this era, but checking the manual is the best practice.
Should I replace the hoses with the pump?
It is highly recommended. The rubber hoses degrade over time and can become hard, brittle, and cracked. A new pump will restore full system pressure, which can cause old, weak hoses to leak or burst. Replacing them with the pump is a smart preventative measure.
