Windshield Washer Reservoir Assembly – OEM‑fit Replacement for Toyota SUVs

Keep your view clear with a fresh washer bottle. This reservoir stores washer fluid and feeds the pump so hood nozzles wash away mud, salt, and bugs. Clean glass means safer night and rain driving and less wiper wear.

Why this part is needed

A sealed, clean tank prevents air from entering the system, protects the pump, and filters debris before it reaches the spray jets. UV‑stable plastic resists heat and chemicals, while a tight cap stops evaporation and odors. Strong, even spray improves visibility and safety.

How it works

The molded jar mounts to factory points, seals with a cap and grommet, and routes fluid through an outlet to the electric pump. The pump then pushes fluid via hoses to the nozzles . Venting prevents vacuum, the strainer traps grit, and some setups include a level port for a sensor.

If it’s damaged

• Cracks or loose grommet = leaks, empty tank, weak or no spray
• Dry pump can overheat and blow a fuse ⚠️
• Dirty fluid clogs jets, causing streaks, glare, and scratched glass

Tech tip

Transfer the pump with a new seal, rinse lines, use winter‑grade fluid, and don’t overtighten brackets. After install, hold the washer switch to bleed air until a solid stream appears.
