Is Your Subaru DL Windshield Washer Pump Failing?
A non-working windshield washer on your 1973-1984 Subaru DL is more than an inconvenience; it's a safety issue. When the pump fails, you lose the ability to clean your windshield on the move. For a vehicle from this era, the cause is almost always a worn-out pump motor.
Symptoms of a Bad Washer Pump
- No Sound, No Spray: The most common symptom is complete silence when you try to use the washers. You won't hear the familiar humming sound of the pump motor. This almost always points to a dead pump or an electrical issue.
- Pump Hums, But No Fluid Sprays: If you can hear the motor running but nothing comes out, the pump might be weak, or you could have clogged nozzles or a leak in the hoses.
- Weak or Uneven Spray: If the fluid barely reaches the windshield or sprays unevenly, the pump motor may be getting weak and failing to create enough pressure.
Check the Basics First
Before ordering a new pump, make sure your washer fluid reservoir is full and check the fuse for the washer system. Sometimes the fix is that simple.
Choosing the Right Aftermarket Pump for Your DL
For a classic vehicle like the 1973-1984 Subaru DL, finding new Original Equipment Manufacturer (OEM) parts is nearly impossible. The good news is that the aftermarket provides reliable and affordable solutions.
OEM vs. Aftermarket
Since your Subaru DL does not have the complex driver-assist systems (ADAS) found in modern cars, a quality aftermarket washer pump is a perfectly suitable and cost-effective choice. These parts are designed to match the fit and function of the original without the high cost or rarity of a new old stock (NOS) OEM part. Forum discussions among owners of older Subarus confirm that using an aftermarket pump is the standard repair.
Available Brands: Trico
Trico is a well-known brand that produces replacement washer pumps. Their products are designed to be direct-fit replacements, meaning they should install easily without needing any modifications. Reviews often note that Trico pumps are built to last and restore the washer system's original performance.
Pro Tip: Check Your Connectors
When you remove the old pump, inspect the electrical connector for any green or white corrosion. Cleaning the contacts with a small wire brush before plugging in the new pump can ensure a solid connection and prevent future issues.

Frequently Asked Questions
Is it hard to replace the washer pump on a 1973-1984 Subaru DL?
No, this is a great job for a beginner. The pump is usually pushed into a rubber grommet on the washer fluid tank. Access may require you to move a splash shield in the wheel well, but the job typically requires only basic hand tools and takes less than an hour.
Do I need to drain the washer fluid to replace the pump?
Yes. When you pull the old pump out of the reservoir, all the fluid will drain out. Have a bucket ready to catch it. This is a good time to clean any debris from inside your reservoir before installing the new pump.
Could the problem be a clog instead of the pump?
Yes. If you can hear the pump motor running but no fluid sprays, the lines or nozzles could be clogged. You can try to clear them with compressed air or a small pin in the nozzle opening. However, if you hear no sound at all, the pump itself has likely failed.
Are there any recalls for the Subaru DL washer pump?
No, there are no known recalls or technical service bulletins (TSBs) from Subaru or the NHTSA for the windshield washer pump on the 1973-1984 Subaru DL. Any recalls you may find are for much newer Subaru models and different components, like wiper motors or fluid level sensors.
Technical Specifications
Typically a 12V DC motor, press-fit into the washer fluid reservoir with one electrical connector and one or two hose outlets.
