Direct-fit washer pump assembly designed for RX300 models, complete with integrated fluid level sensor. This is the pump and motor unit that pressurizes washer fluid to your nozzles. Keeps your windshield clean without the guesswork of manual fluid checks.
Will this pump work with my existing washer fluid reservoir?
Yes. This is a direct OEM-equivalent replacement that mounts into the factory reservoir. No modifications needed to the tank itself.
Does the sensor wire just plug in, or do I need to splice anything?
The sensor connector matches the factory harness on RX300 models — it plugs straight in. No splicing or adapters required.
What if the pump arrives and doesn't prime or seems slow?
Fill your washer reservoir completely and run the system for a few seconds to purge air from the lines. If it still doesn't pressurize, contact us for a return — we cover defects on arrival.
Products are direct shipped from Supplier.
