A Guide to the 1957-1964 Buick Roadmaster Windshield Washer Pump
Keep your classic Roadmaster's windshield clear by understanding its unique washer system.
- The 1957-1964 Roadmaster uses a vacuum-operated washer pump, not a modern electric one.
- Trico was the original manufacturer, and their aftermarket kits are the closest to the original design.
- Before replacing the pump, check for simpler issues like an empty fluid jar, clogged nozzles, or cracked vacuum hoses.
- Replacement is a straightforward DIY job that typically takes less than an hour.
Symptoms of a Failing Windshield Washer Pump
When the washer pump on your Roadmaster begins to fail, the signs are usually straightforward. Recognizing them early can help you address the issue before you're caught in a situation with a dirty windshield.
- No Fluid Spray: The most obvious symptom is when no washer fluid sprays onto the windshield when you activate the control. If you can't hear any sound from the pump, it may have failed or is not receiving vacuum.
- Weak or Inconsistent Spray: If the fluid just dribbles out or sprays unevenly, the pump may be losing its ability to create strong suction. This can also be caused by clogged nozzles or cracked vacuum lines.
- Visible Leaks: You might notice washer fluid leaking under the car or around the washer fluid jar. The pump assembly includes seals that can dry out and crack over time.
Choosing the Right Aftermarket Pump
For a classic vehicle like the 1957-1964 Roadmaster, you won't find new original equipment (OEM) parts sitting on a shelf. Your options are primarily new aftermarket parts, New Old Stock (NOS), or used parts. For reliability and availability, a new aftermarket part is often the best choice.
| Brand Tier | Brand(s) | Quality & Notes |
|---|---|---|
| OEM-Equivalent | Trico | Trico was the original manufacturer for General Motors' vacuum wiper and washer systems during this era. An aftermarket Trico pump or repair kit is the closest you can get to the original design and function. These kits are often designed for easy installation and are a reliable choice for restoring original functionality. |
Pro Tip: Before replacing the pump, always check the basics. Ensure the washer fluid jar is full, the nozzles aren't clogged with wax or debris, and the vacuum hoses are not cracked, disconnected, or leaking. Sometimes the problem is simpler than a failed pump.
Frequently Asked Questions
Is the windshield washer pump on a 1957-1964 Roadmaster electric?
No, it is not. These vehicles use a vacuum-operated system that is tied into the vacuum wiper motor. This is a key difference from modern cars and requires checking vacuum lines for leaks as part of troubleshooting.
Can I replace just the pump, or do I need a whole kit?
Often, you will be buying a repair kit. For example, Trico offers kits that include the necessary components to restore the pump's function. Given the age of the vehicle, replacing the associated seals and diaphragms included in a kit is a good idea, even if only one part has failed.
Is replacing the washer pump a difficult job for a DIYer?
No, this is generally considered an easy DIY task. The pump is usually accessible in the engine bay, mounted to the washer fluid jar. Trico replacement kits often come with instructions to guide you through the process.
Are there any recalls on the washer pump for this vehicle?
There are no active or past recalls on the NHTSA database for the windshield washer pump on the 1957-1964 Buick Roadmaster. Recalls listed for the Roadmaster nameplate are for much newer models from the 1990s.
