Product Introduction

• Structure: Blow-molded from high-density polyethylene (HDPE) plastic, featuring a contoured design to fit the cab’s under-hood layout. It integrates a built-in 24V washer pump, a fluid level sensor with electrical connector, a twist-lock filler cap, and integrated mounting brackets. The tank has a sealed construction to prevent fluid leakage and contamination.

• Performance: The HDPE material is resistant to washer fluid corrosion, UV radiation, and temperature extremes (-40℃ to 80℃). The built-in pump provides consistent fluid pressure for effective windshield cleaning, while the level sensor triggers a dashboard warning when fluid is low. The sealed design prevents evaporation and contamination, ensuring reliable performance in harsh operating conditions.

Core Function

1. Fluid Storage: Stores windshield washer fluid for the front and (optionally) rear window cleaning systems, with a capacity optimized for long-distance trucking.

2. Integrated Pump & Sensor: The built-in washer pump delivers pressurized fluid to the windshield nozzles, while the level sensor monitors fluid levels to alert the driver when a refill is needed.

3. Contamination Prevention: The sealed filler cap and tank construction prevent dust, debris, and water from entering the system, maintaining the cleanliness of the washer fluid.

Application Scenarios – Where This Washing Tank Performs Best

The Washing Tank 810W26481-0079 is specifically designed for the Sinotruk Sitrak heavy-duty truck series. However, its application extends across multiple real-world scenarios that demand dependable cab components:

• Long-Haul Logistics Fleets: Trucks covering thousands of kilometers weekly accumulate dust, mud, and insect residue rapidly. A fully functional washing system is non-negotiable for driver safety, and this tank ensures uninterrupted fluid supply.
• Construction and Mining Operations: In these harsh environments, dust clouds and debris constantly compromise windshield visibility. The robust HDPE construction of this tank resists impacts from loose gravel and stones thrown up during off-road operations.
• Municipal and Waste Management Vehicles: Sitrak trucks operating in urban waste collection face chemical exposure from road salts and waste liquids. The corrosion-resistant design of this washing tank handles these challenges without degradation.
• Cold-Climate Transport: Operating in regions where temperatures plunge below -30°C, this tank’s material flexibility prevents cracking—a common failure point in inferior aftermarket alternatives.

Essentially, if your Sitrak truck operates anywhere that challenges visibility, this washing tank is the component that keeps your drivers safe and your fleet compliant with road safety regulations.

Customer Case Study – Washing Tank 810W26481-0079 in Action

Earlier this year, a fleet procurement manager from East Africa reached out to us with a recurring problem. His company operated 120 Sinotruk Sitrak trucks on intercity cargo routes, and they were experiencing frequent windshield washer failures. The aftermarket washing tanks they’d been sourcing locally cracked within months due to UV exposure and vibration fatigue.

After reviewing their requirements, we recommended our Washing Tank 810W26481-0079 for Sinotruk Sitrak as a direct OEM-spec replacement. We shipped an initial trial order of 30 units with neutral packaging. The installation was plug-and-play—no bracket modification, no adapter needed.

Three months later, not a single unit had failed. The client returned with a follow-up order of 200 units, this time requesting custom-branded packaging featuring their company logo. Today, they rely on Mettlead as their sole-source supplier for all Sitrak cab components, including washing tanks, mirror assemblies, and wiper systems.

This is what happens when quality meets reliability. And it starts with choosing the right Sitrak Washing Tank 810W26481-0079 from a supplier who actually manufactures—not just trades.
