Is Your Volvo S70 Washer Pump Failing?
A non-working windshield washer system can be a safety issue, especially in bad weather. For the 1998-2000 Volvo S70, the cause is often a failed pump, but it can also be something simpler. Before you buy a new part, check for these common symptoms to properly diagnose the problem.
Symptoms of a Bad Windshield Washer Pump
- No Sound, No Spray: You pull the lever and nothing happens. You don't hear the familiar hum of the pump motor. This almost always means the pump has failed electrically or isn't getting power.
- Pump Hums, But No Fluid Sprays: If you can hear the pump motor running but no fluid comes out, the problem could be a clogged line, frozen fluid, or an internally failed pump that can no longer create pressure.
- Weak or Uneven Spray: If the fluid barely reaches the windshield, the pump motor may be getting weak and losing its ability to pressurize the fluid effectively.
- Leaks: Puddles of blue or green washer fluid under the front passenger side of the car can indicate a cracked pump housing or a bad seal where the pump enters the reservoir.
Pro Tip: Check for Clogs First
Before blaming the pump, check for common blockages. On these Volvos, the small rubber check valves in the washer lines under the hood can get clogged. Also, mixing different brands of washer fluid can sometimes cause the liquid to congeal into a gel, blocking the pump's filter screen. It's worth flushing the system and cleaning the nozzles first.
Choosing the Right Aftermarket Washer Pump
For the 1998-2000 S70, you don't need to buy a Genuine Volvo part to get your washers working again. Aftermarket pumps are affordable and readily available. The main difference between brands is often build quality and longevity. Here’s a breakdown of the available options.
| Brand Tier | Brands | Quality & Price Assessment |
|---|---|---|
| Good | Professional Parts Sweden, Trico | These brands offer a good balance of affordability and reliability. Professional Parts Sweden is a known supplier of aftermarket Volvo parts, though some components are made in China to keep costs down. Trico is a major name in wiper systems and designs their pumps to match original equipment (OE) specifications for a straightforward fit. For a daily driver, these are solid, budget-friendly choices. |
| Better | Vemo | Vemo positions itself as an OE-quality supplier. While user reviews for the brand are generally mixed across different types of parts, they are often built to a higher standard than basic economy brands. If you want a bit more peace of mind without paying for a genuine part, Vemo is a reasonable step up. |
| Best | Genuine Volvo | The original pump from Volvo is the benchmark for quality, fit, and durability. While it's the most expensive option, it guarantees perfect compatibility. However, for a component like a washer pump on an older vehicle, most owners find aftermarket options provide perfectly acceptable performance for a fraction of the price. |
Known Issues, Recalls, or TSBs
There are no known recalls or Technical Service Bulletins (TSBs) from the NHTSA specifically for the windshield washer pump on the 1998-2000 Volvo S70. Any failures are typically due to normal age and wear of the part.
DIY Replacement Guide
Replacing the washer pump is a manageable DIY job that takes about an hour. The pump is located at the bottom of the washer reservoir in the passenger-side wheel well.
- Access the Pump: Jack up the front passenger side of the car and remove the wheel. Then, remove the plastic inner fender liner to expose the washer reservoir and pump. Some mechanics prefer to remove the entire front bumper for easier access, but it's not always necessary.
- Drain the Fluid: Place a bucket underneath the pump. When you disconnect the pump, all the remaining fluid in the reservoir will drain out.
- Remove the Old Pump: Disconnect the electrical connector and the washer fluid hose. The pump is simply press-fit into a rubber grommet; wiggle and pull it straight out of the reservoir.
- Install the New Pump: Clean the grommet and the opening on the reservoir. Lubricate the new pump's inlet with a little washer fluid and press it firmly into the grommet. Reconnect the electrical plug and hose, refill the reservoir, and test the system before putting the fender liner and wheel back on.
Common Ordering Mistake
The 1998-2000 Volvo S70 sedan uses a single-outlet pump for the front windshield. Wagons (V70) and models with headlight washers may use a different dual-outlet pump. Ensure you are ordering the correct pump for your specific vehicle configuration. The OEM part number for the S70 front pump is 9169611.
Frequently Asked Questions (FAQ)
Can I drive my S70 with a broken washer pump?
Yes, you can still drive the car. However, a non-functional washer system can be a safety hazard if your windshield becomes obscured by dirt, salt, or spray, so it should be repaired as soon as possible.
Why do I hear the pump but nothing sprays out?
This is a common issue. It could be an empty reservoir, a hose that has disconnected, or a clog in the system. Check the small filter screen on the pump's inlet grommet and the check valves in the lines under the hood, as they often get blocked with debris or gelled fluid.
Is it hard to replace the washer pump myself?
No, it's a fairly simple job for a DIYer with basic tools. The main challenge is accessing the pump behind the fender liner. It should take about an hour.
Do I need to remove the front bumper to change the pump?
It is not strictly necessary, but many find it makes the job much easier. You can typically access the pump by just removing the passenger-side front wheel and inner fender liner.
