Is Your Windshield Washer Pump Failing?
A working washer system is critical for safety, especially in bad weather. For the 1980-1986 Impala, the washer pump is a mechanical part that works in tandem with your wiper motor. When it fails, you lose the ability to clean your windshield on the move. Because it's a mechanical part tied to the wiper motor, diagnosing it is a little different than on newer cars.
Common Symptoms of a Bad Washer Pump
- No Fluid Spray: When you activate the washer, the wipers move but no fluid sprays onto the windshield.
- Wipers Move, No Pump Sound: You won't hear the typical hum of an electric pump. The key symptom is a lack of fluid when the wipers are activated for a wash cycle.
- Leaking Fluid: You might find a puddle of washer fluid under the reservoir, indicating a cracked pump housing or a bad seal.
Choosing the Right Aftermarket Part
For a classic vehicle like the 1980-1986 Impala, finding new original equipment (OEM) parts from GM is nearly impossible. The market is served by aftermarket manufacturers that produce new parts designed to fit and function like the original.
Brand Quality: ACDelco
ACDelco is the only brand available for this specific part. Fortunately, ACDelco has a long history as a GM-owned parts supplier, and their products are often the same as the original factory components. For a GM vehicle, choosing ACDelco provides confidence in fit, form, and function, making it a reliable choice for keeping your Impala's washer system working properly. It is considered a top-tier option for GM vehicles.
Pro Tip: Before replacing the pump, check the simple things first. Make sure your washer fluid reservoir is full. Check the hoses for cracks or clogs, and inspect the spray nozzles to see if they are blocked with wax or debris. Sometimes the problem isn't the pump at all.

Frequently Asked Questions
Can I replace the washer pump myself?
Yes, this is a very DIY-friendly job for a beginner. The pump is typically located on the side of the washer fluid reservoir in the engine bay. It usually requires simple hand tools to access and replace. The entire job can often be done in under an hour.
My wipers work, but the washer doesn't. Is it always the pump?
Not always. On these older GM vehicles, the washer function is activated by a mechanism on the wiper motor. The problem could be a clogged filter in the reservoir, cracked or disconnected hoses, or a blocked nozzle. In some GM vehicles of this era, electrical issues in the wiper circuit board could also prevent the washer function from working, even if the wipers themselves move.
Do I need to prime the new washer pump?
Generally, no priming is required. Once the new pump is installed and the reservoir is full, activating the washer function a few times should be enough to draw fluid through the lines and get the system working.
Are there any recalls for the windshield washer pump on my Impala?
Based on searches of the National Highway Traffic Safety Administration (NHTSA) database, there are no specific recalls for the windshield washer pump on the 1980-1986 Chevrolet Impala.
