Product Introduction

• Structure: A compact, high-efficiency aluminum heat exchanger with a dense fin-and-tube design. It features inlet/outlet connections for the engine coolant and sealed headers to prevent leaks.

• Performance: Transfers heat from the engine’s hot coolant to the air blown into the cab, providing reliable heating and defrosting performance even in extreme cold. The aluminum construction ensures excellent thermal conductivity and corrosion resistance.

• Design: Directly interchangeable with the original equipment heater core, engineered to match the HVAC system’s mounting points and coolant line connections for a perfect, factory-like fit.

Core Function

1. Cab Heating: Transfers heat from the engine coolant to the cabin air, maintaining a comfortable interior temperature for the driver and passengers.

2. Windshield Defrosting/Defogging: Provides warm, dry air to clear ice, frost, and fog from the windshield, ensuring optimal visibility in cold or humid conditions.

3. Heat Exchange Efficiency: The dense fin design maximizes the surface area for heat transfer, ensuring rapid and uniform heating of the cab.

Heated Water Tank 8101020C6100 Dongfeng – OEM-Grade Cabin Heating Component

When temperatures plunge below freezing, your Dongfeng fleet depends on a reliable heated water tank to keep cabin heating systems responsive and drivers comfortable. The Heated Water Tank 8101020C6100 Dongfeng from METTLEAD Truck Parts delivers factory-matched performance at a direct-supply price — ensuring your trucks stay operational through the harshest winter corridors without costly downtime.

Why This Heated Water Tank Matters to Your Fleet

The heated water tank sits at the heart of the cab heating circuit. It stores and pre-heats coolant before circulating it through the heater core, giving drivers instant warmth during cold starts and maintaining stable cabin temperatures on long hauls. A degraded or failed unit forces drivers to idle engines excessively — burning fuel, accelerating wear, and violating many countries’ anti-idling regulations.

Key Features and Benefits

• Exact OEM Fitment — Manufactured to match Dongfeng’s original specification for part number 8101020C6100, eliminating modification or adapter requirements.
• Corrosion-Resistant Inner Shell — Engineered with anti-rust treated aluminum alloy to withstand mixed-coolant environments and extend service life beyond 200,000 km under normal operating conditions.
• Rapid Heat Transfer Design — Optimized internal baffling accelerates coolant heating by up to 30% compared to aftermarket alternatives, reducing warm-up time in sub-zero climates.
• Pressure-Tested Sealing — Every unit undergoes 1.5 bar hydrostatic pressure testing to ensure zero-leak performance across a working temperature range of −40 °C to +120 °C.
• Plug-and-Play Electrical Connector — Factory-matched wiring harness plug for seamless integration with the Dongfeng HVAC control module.
• Weight-Optimized Construction — Lightweight yet durable build reduces dead weight on the cab frame without compromising structural integrity.

Technical Specifications

Application and Vehicle Fitment

The Heated Water Tank 8101020C6100 is engineered specifically for the following Dongfeng commercial vehicle platforms:

• Dongfeng Kinland Series (KL, KX) — Long-haul tractor units operating in Northern China, Russia, Central Asia, and Eastern European corridors.
• Dongfeng Tianlong (DFL4251) — Heavy-duty logistics trucks requiring dependable cabin comfort during winter freight operations.
• Dongfeng Tianjin Medium-Duty Range — Regional distribution vehicles exposed to cold-start conditions in continental climates.

Fleet operators running Dongfeng trucks across cold-climate routes — from the Siberian Highway to Scandinavian freight lanes — rely on this heated water tank to maintain driver welfare, reduce engine idling time, and meet occupational comfort standards.

Customer Case Study: Heated Water Tank 8101020C6100 Dongfeng in Action

A logistics fleet operator managing 120+ Dongfeng Kinland tractors across Kazakhstan and Russia approached METTLEAD in Q4 2023. Their existing aftermarket heated water tanks were failing prematurely — averaging just 80,000 km before leaking — causing unscheduled maintenance stops and driver complaints during −35 °C winter operations.

After switching to METTLEAD’s Heated Water Tank 8101020C6100 Dongfeng, the fleet recorded the following results over a 6-month tracking period:

• Zero premature failures across 120 installed units.
• Average warm-up time reduced by 25%, translating to approximately 1.2 liters of diesel saved per truck per cold start.
• Driver satisfaction scores for cabin comfort increased from 6.1/10 to 9.2/10.
• Procurement cost reduced by 18% compared to their previous third-party supplier, thanks to METTLEAD’s factory-direct pricing model.

The customer has since placed three repeat orders and expanded their METTLEAD parts catalog to include additional Dongfeng HVAC and cooling system components.

Frequently Asked Questions

What does the Heated Water Tank 8101020C6100 actually do in the Dongfeng cab heating system?

It acts as a reservoir and pre-heating chamber for engine coolant before it enters the cabin heater core. By maintaining a reserve of heated coolant, the tank ensures immediate warmth delivery upon activating the cab heater — even during cold starts when the engine block hasn’t fully reached operating temperature.

How do I know if my heated water tank needs replacement?

Common symptoms include slow cabin warm-up times, coolant puddles beneath the cab, visible corrosion or cracking on the tank housing, or electrical fault codes related to the heating circuit. If the tank has exceeded 200,000 km without service, preventive replacement is recommended.

Is this heated water tank compatible with mixed coolant types?

Yes. The internal alloy treatment is designed to resist corrosion from both ethylene glycol and propylene glycol-based coolants. However, we recommend maintaining the coolant concentration and type specified in your Dongfeng operator manual for optimal longevity.

Can this part be installed without specialized tools?

The 8101020C6100 heated water tank uses a bolt-on OEM bracket pattern and a plug-and-play wiring connector. A standard mechanic toolkit is sufficient for installation. Typical replacement time is 30–45 minutes for an experienced technician.

What is the expected service life of this heated water tank?

Under normal operating conditions and proper coolant maintenance, the tank is designed to deliver reliable service for 200,000 km or more. Units operating in extreme conditions (sustained sub-zero temperatures, high-mineral water regions) should be inspected annually.

Does METTLEAD offer a warranty on this heated water tank?

Yes. All METTLEAD heated water tank units ship with a standard quality guarantee. If a unit fails due to manufacturing defect within the warranty period, we provide free replacement. Specific warranty terms are confirmed at the time of order.
