1985-1989 Subaru DL Windshield Washer Pump Replacement Overview
If your washer fluid isn't spraying, the pump is the most likely reason—here's what you need to know.
- For a 1985-1989 Subaru DL, an aftermarket Trico pump is the most practical and available replacement option.
- The most common symptom of failure is silence from the pump when the washer is activated; always check the fuse first.
- Replacement is a simple, DIY-friendly job that can be done in under an hour with basic tools.
- Your DL may have a separate pump and tank for the rear washer (on wagons), so confirm you are ordering the correct part for the front.
Is Your Subaru DL's Washer Pump Failing?
A non-working windshield washer is more than just an inconvenience; it's a safety hazard. When the pump fails, you can't clear your windshield of road grime, dust, or salt spray. For most 1985-1989 Subaru DL owners, the first sign of trouble is when nothing happens after pulling the washer lever. You might not hear the familiar whirring sound of the pump motor, and no fluid sprays onto the glass.
Diagnosing the Problem
Before you replace the pump, it's good to confirm it's the problem. Here are the common signs of a bad windshield washer pump:
- No Sound, No Spray: If you activate the washer and hear nothing, the pump motor has likely failed or isn't getting power. First, check the fuse for the wiper/washer system. If the fuse is good, the pump itself is the next logical culprit.
- Pump Hums, But No Fluid Sprays: If you can hear the pump motor running but no fluid comes out, the reservoir might be empty. If it's full, the pump's internal impeller could be broken, or the lines or nozzles might be clogged.
- Weak or Uneven Spray: A weak spray can be caused by clogged nozzles or a pump that is starting to fail and can no longer generate enough pressure.
Pro Tip: Check for Clogs First
Before ordering a new pump, disconnect the hose from the base of the spray nozzles and aim it into a towel. Activate the washer. If fluid shoots out of the hose, your pump is working and the nozzles are just clogged. You can often clear them with a small pin or compressed air.
Choosing the Right Aftermarket Part
For a vehicle like the 1985-1989 Subaru DL, finding a new Original Equipment Manufacturer (OEM) washer pump is nearly impossible. Fortunately, the aftermarket provides reliable and affordable solutions. Trico is a well-known brand that manufactures replacement washer pumps designed to meet or exceed original specifications. These pumps are designed for easy installation without needing modifications. Given the age of the vehicle, a quality aftermarket pump from a brand like Trico is the best and most practical choice.

Frequently Asked Questions (FAQ)
Where is the washer pump located on my Subaru DL?
On pre-1995 Subaru vehicles like your DL, the front washer pump is located at the bottom of the windshield washer fluid reservoir in the engine bay, usually near the battery. If your DL is a wagon, it may have a separate pump and reservoir for the rear window located in the rear cargo area. The replacement part discussed here is for the front windshield.
Can I replace the washer pump myself?
Yes, this is a very DIY-friendly repair. The process typically involves accessing the washer fluid reservoir, which may require moving the battery or other components for clearance. You'll need to drain any remaining fluid, disconnect one electrical plug and one hose, and pull the old pump out from the reservoir. The new pump simply presses into the same spot.
Do I need any special tools for this job?
No special tools are required. You will need basic hand tools like a socket set or screwdrivers and a container to catch the old washer fluid. The job is straightforward and can usually be completed in under an hour.
Is a weak spray always a sign of a bad pump?
Not always. A weak or uneven spray can also be caused by clogged washer nozzles or a leak in the fluid lines. It's a good idea to check for these simpler issues before replacing the pump. You can use a thin wire or pin to try and clear the nozzles.
