Windshield Washer Fluid Reservoir Tank with Pump - Direct Fit

In this review the focus is a direct-fit windshield washer fluid reservoir tank with pump designed for a range of Kenworth and Peterbilt trucks. The bottom line: this replacement reservoir is for truck owners and fleet technicians who need a like-for-like part that restores washer function without custom modification. The most compelling reason to buy is the complete unit arriving with the pump included, which eliminates the need to transfer components from the old tank and simplifies installation for anyone replacing a cracked or leaking reservoir.

Key Features

• Direct replacement: Built to match the original form and function so the tank installs and plugs in with minimal adjustments.
• Includes pump: Supplied with a pump that circulates washer fluid through the lines to the nozzles, restoring spray performance immediately.
• Durable materials: Constructed from heat-resistant plastic chosen to withstand underhood temperatures and vibration for longer service life.
• Wide compatibility: Designed to fit many model years of Kenworth T680/T880 and multiple Peterbilt models, reducing the risk of a parts mismatch.
• OEM reference numbers: Replaces OE 603-5402 and N5355001, which helps confirm fitment for owners using original part numbers.
• Warranty support: Backed by a 12-month replacement or refund policy for added buyer confidence.

Who It's For

This reservoir is targeted at Kenworth and Peterbilt owners, maintenance shops, and fleet managers who need a reliable, OEM-style replacement after a crack, leak, or pump failure. It is especially useful when the goal is a fast, plug-and-play swap without fabricating brackets or modifying wiring.

It is less suitable for trucks outside the listed model years or owners who require a custom reservoir with different capacity or mounting locations; always verify the compatibility list before purchase to avoid returns.
