GMC Safari Power Steering Pump Replacement Guide (1985-1995)
Everything a GMC Safari owner needs to know about diagnosing and replacing a failing power steering pump.
- A whining noise that changes with engine speed is the #1 symptom of a failing pump.
- You MUST use a special power steering pulley puller/installer tool to do this job.
- Aftermarket remanufactured pumps have inconsistent quality; be prepared for potential issues.
- Properly bleeding the air out of the system after installation is critical to prevent noise and damage to the new pump.
Is Your GMC Safari Power Steering Pump Failing?
A bad power steering pump on your Safari van will give you clear warning signs. The most common is a loud whining or groaning noise that changes pitch as you rev the engine or turn the steering wheel. You might also feel that the steering has become very stiff and hard to turn. Look under the front of your van for reddish-brown fluid leaks, a sure sign of a problem. If you check the fluid in the reservoir and it looks foamy or has shiny metal flakes in it, the pump is likely failing and contaminating the system.
Critical Failure Warning
If a power steering pump seizes completely, it can snap the serpentine belt. This will cause your engine to overheat and your battery to stop charging, leaving you stranded. Do not ignore the symptoms.
🎬 Watch: How to diagnose a bad power steering pumpKnown Issues for 1985-1995 GMC Safari
While there are no widespread recalls specifically for the power steering pump on these vans, there are some official service bulletins and related issues to be aware of:
- 1985 Steering Gear Recall: For the 1985 model year only, a recall was issued for the steering gear's attachment to the frame, which could crack and cause a loss of steering control.
- Cold Weather Noise/Leaks: General Motors released a Technical Service Bulletin (TSB) for many vehicles, including these Safaris, noting that in extremely cold temperatures (below -22°F / -30°C), the power steering fluid can thicken and cause leaks or noise. The official fix is to use GM's Cold Climate power steering fluid.
- Hydro-Boost Contamination: On models with a Hydro-Boost brake system, a failing power steering pump can send debris into the brake booster, causing brake problems. This makes it essential to flush the entire system when you replace the pump.
Choosing a New Aftermarket Pump: Cardone vs. BBB Industries
For a vehicle of this age, finding a brand-new OEM power steering pump is nearly impossible. Your main options are remanufactured pumps from aftermarket brands like Cardone and BBB Industries. It is important to be realistic about these parts.
Both Cardone and BBB Industries are major suppliers of remanufactured parts. They serve as a budget-friendly way to get your van back on the road. However, owner experiences and forum discussions show that quality control can be inconsistent. It is not uncommon to receive a part that is defective out of the box or fails within a few months.
- Tier 1 (Best Available): A professionally rebuilt original OEM pump. This is often the most reliable but requires finding a specialized shop.
- Tier 2 (Budget Options): New or remanufactured pumps from Cardone or BBB Industries. They are widely available and affordable. Be aware of the mixed reviews regarding long-term reliability. When buying one, inspect it carefully before installation and be prepared for the possibility of a warranty exchange.
Pro Tip: Bleed the System Correctly
The number one reason a new power steering pump is noisy is because of air trapped in the system. After installation, you MUST bleed the system by raising the front wheels and turning the steering wheel from lock to lock at least 15-20 times with the engine OFF. Check and top off the fluid, then repeat with the engine running.

Frequently Asked Questions (FAQ)
Do I need special tools to replace the pump?
Yes. You absolutely need a power steering pulley puller and installer kit. The pulley on your Safari's pump is press-fit and must be removed to get to the mounting bolts. Trying to use a generic puller or a hammer will destroy the pulley and possibly the new pump. You can often rent these kits from auto parts stores.
🎬 Learn how to use a pulley puller and installer toolCan I reuse my old power steering fluid?
No. Never reuse old fluid. When a pump fails, it often releases tiny metal particles into the fluid. Reusing this contaminated fluid will quickly destroy your new pump. You must flush the entire system and use new, clean fluid of the correct type.
What's the difference between the pump and the reservoir?
On the 1985-1995 GMC Safari, the pump and the fluid reservoir are two separate parts. The pump is located low on the driver's side of the engine, while the plastic reservoir where you check and add fluid is mounted higher up for easy access. They are connected by rubber hoses.
My new pump is whining. Is it bad?
Not necessarily. The most common cause of a whining noise after replacement is air trapped in the system. Before you assume the pump is bad, make sure you have performed the bleeding procedure correctly. If the noise persists after proper bleeding, the pump may be defective.
