A Note on the Buick Roadmaster
Before searching for parts, it's important to clarify that Buick did not produce the Roadmaster model between the years 1959 and 1990. The classic era for the Roadmaster ended in 1958, and the name was later revived in 1991. If you own a full-size Buick from 1965-1969, you likely have a LeSabre, Wildcat, or Electra. This guide provides information relevant to those models.
Symptoms of a Failing Windshield Washer Pump
When a washer pump starts to fail on a mid-60s Buick, the signs are usually straightforward. You might hear the pump motor whirring but see no fluid spray, or the spray might be very weak and inconsistent. Sometimes, the pump fails completely and makes no sound at all. You may also notice washer fluid leaking from the pump itself, which is often located on or near the washer fluid reservoir.
Washer Pump Cost for 1965-1969 Full-Size Buicks
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $50 - $120 |
| Used or NOS (New Old Stock) | Varies widely |
| Shop Labor | $60 - $150 |
Choosing the Right Aftermarket Pump
For Buicks from the 1965-1969 era, true OEM parts are no longer manufactured. Your options are primarily New Old Stock (NOS) parts, which are rare and expensive, or new aftermarket reproductions. Fortunately, several companies manufacture replacement washer pumps that fit a wide range of classic GM vehicles.
Pro Tip: Many washer pumps from this era were shared across different GM models, including Chevrolet, Oldsmobile, and Pontiac. A part listed for a 1965 Buick LeSabre or a 1969 Electra will likely fit other full-size Buicks from the same period. Always check the part's specific vehicle application list.
Available Aftermarket Brands
- OER (Original Equipment Reproduction): OER specializes in reproduction parts for classic GM cars and offers a direct-fit replacement washer pump for many 1963-1969 Buick models.
- ACI: ACI provides aftermarket washer pumps that are engineered to match the fit and function of the original equipment.
- Trico: Trico, a long-standing name in wiper systems, offers universal and direct-fit washer pumps that are known for easy installation.
Common Ordering Mistake
Be aware that GM used different pumps for cars with and without recessed (or "hidden") wipers. Some replacement pumps are specifically for one design. For example, some pumps are noted for use on vehicles *without* recessed wipers. Check your vehicle's specific wiper system before ordering.
Frequently Asked Questions (FAQ)
Is it difficult to replace a windshield washer pump on a 1960s Buick?
No, it is generally an easy repair. The pump is typically mounted directly to the washer fluid reservoir with a couple of screws and is easily accessible in the engine bay. The process involves disconnecting the electrical connector and fluid hoses, unbolting the old pump, and installing the new one.
Are there any recalls for 1965-1969 Buick washer pumps?
No recalls were found related to the windshield washer pumps for Buick models from this period. These components are simple and generally fail due to age rather than a manufacturing defect.
Can I just buy a rebuild kit for my original pump?
Yes, rebuild kits for original Trico or GM washer pumps are sometimes available from specialty classic car part suppliers. These kits can be a good option if you want to maintain the originality of your vehicle, but a complete new aftermarket unit is often a simpler and more reliable repair.
What other parts should I inspect when replacing the pump?
While replacing the pump, it's a good idea to inspect the rubber washer fluid hoses for cracks and brittleness. Also, check the spray nozzles on the hood to ensure they are not clogged with wax or debris. These are inexpensive and easy to replace if needed.
