Detailed Description

This Dorman windshield washer check valve, part number 926-335, is built to replace a failed OE-style valve in the washer fluid line. When the original valve binds or cracks, washer pressure can drop and spray performance can become inconsistent. This replacement helps restore proper fluid control for vehicles such as the Toyota Tacoma, Toyota Tundra, Lexus RX350, and Lexus ES350 across the listed model years.

This part cross-references Toyota (e.g., 8532128020) for the same application.

What It Helps Solve
