What this part does

The washer fluid reservoir is a molded plastic storage container positioned in the front engine bay or behind the front fender liner. It holds the cleaning solution utilized by the windshield wipers and, depending on the equipment level, the headlight washer jets. The tank provides the mounting points for the electric washer fluid pumps and the internal fluid level sensor. Prolonged exposure to engine bay heat and constant road vibration can cause the plastic seams or the filler neck to fatigue and crack. When the tank fractures, the system will continuously leak fluid onto the ground, leaving the washer system inoperative and triggering a persistent low fluid warning message on the instrument cluster.

Before you order

Match the part number stamped into the plastic of your original tank with the numbers listed above to ensure correct fitment. Vehicles equipped with the cold weather package or headlight washers often utilize a different tank variant with secondary pump provisions, making direct visual comparison necessary. Bear in mind that this housing does not typically include the washer pumps, the fluid level sensor, or the filler neck unless explicitly shown in the photographs; you will need to transfer those components from the vehicle it came from. It is highly recommended to replace the rubber sealing grommets for the washer pumps during the swap, as old, hardened grommets are a primary source of fluid leaks after installing a replacement reservoir.
