This windshield washer fluid reservoir — also referred to as a washer tank, washer bottle, or fluid reservoir — is a critical component of the vehicle's windshield cleaning system. When the original reservoir cracks or fails, this replacement restores leak-free fluid storage and reliable pump operation. Designed specifically for single-pump Wrangler TJ models; dual-pump applications require a different part number.
