1986-1987 Chevrolet Nova Washer Pump Replacement and Diagnosis
If your windshield washers have stopped spraying, a failed pump is a likely cause on your Chevrolet Nova.
- The 1986-1987 Nova is based on a Toyota Corolla, and its parts are known for simplicity and reliability.
- Before replacing the pump, always check for simple fixes: ensure the fluid tank is full, the fuse is good, and the spray nozzles are not clogged.
- A new aftermarket pump is the best value, offering better reliability than a used part from a junkyard.
- Replacement is a simple DIY task that usually takes less than 30 minutes and requires no special tools.
Is Your 1986-1987 Nova Washer Pump Failing?
A non-working windshield washer system on your Chevy Nova is usually caused by a few simple issues. Before assuming the pump is bad, it's important to check the basics. The 1986-1987 Nova was built in partnership with Toyota, sharing many parts with the Toyota Corolla of the same era. This means the components, including the washer pump, are known for being straightforward and reliable, but they can still fail with age.
Initial Diagnostic Checks
Before spending money on a new part, perform these simple checks:
- Check Fluid Level: Make sure the washer fluid reservoir is not empty.
- Listen for the Pump: Have a helper activate the washer switch while you listen near the front of the car where the fluid reservoir is located. If you hear a humming or buzzing sound, the pump is getting power and the problem is likely a clog. If you hear nothing, the pump motor may have failed or there's an electrical issue.
- Inspect Nozzles: Use a small pin or needle to gently clean out the washer nozzles on the hood, as they can get clogged with wax and debris over time.
- Check the Fuse: The washer pump is protected by a fuse. Often, it shares a fuse with the wiper motor. If your wipers work, the fuse is probably good.
Choosing the Right Aftermarket Washer Pump
For a vehicle like the 1986-1987 Nova, finding a brand-new original equipment (OEM) washer pump from GM is highly unlikely. The choice is between a used OEM part from a salvage yard or a new aftermarket part.
Installation Overview
Replacing the washer pump on a 1986-1987 Nova is a job most DIYers can handle. The pump is typically located at the bottom of the washer fluid reservoir and is held in place by a rubber grommet.
- Locate the Reservoir: Open the hood and find the washer fluid reservoir. You may need to remove a plastic splash shield in the wheel well for better access.
- Drain Fluid (Optional): Prepare for some fluid to spill out. You can either drain the tank or quickly swap the pumps.
- Disconnect and Remove: Unplug the electrical connector and pull the washer hose off the old pump. Then, firmly pull the pump out of the reservoir.
- Install New Pump: Clean the area, install the new rubber grommet that comes with the new pump, and press the new pump firmly into place. Reconnect the hose and electrical plug.
- Test: Refill the reservoir with washer fluid and test the system before putting any covers back on.

Frequently Asked Questions (FAQ)
Why do I hear the pump but no fluid sprays out?
This usually means the pump motor is working, but there's a blockage. The most common causes are an empty reservoir, clogged washer nozzles on the hood, or a cracked or disconnected hose between the pump and the nozzles.
Is the washer pump the same as the wiper motor?
No. The wiper motor moves the wiper arms back and forth. The washer pump is a separate, smaller motor that only pumps fluid. On some older GM vehicles, the pump was mechanically driven by the wiper motor, but on your Nova, it is a separate electric unit.
Can I use just water in my washer reservoir?
It is not recommended. Windshield washer fluid contains cleaning agents to break down grime and has antifreeze properties to prevent the system from freezing and cracking in cold weather.
Are there any recalls for the 1986-1987 Nova washer pump?
No, there are no active recalls or Technical Service Bulletins (TSBs) from the NHTSA for the windshield washer pump on the 1986-1987 Chevrolet Nova.
