S8710-71310 Heater Core Radiator Aluminum For Japanese Hino 700

S8710-71310 Heater Core Radiator Aluminum For Japanese Hino 700

• 1. Primary Application: Directly compatible with Hino 700 Series (Profia) heavy-duty trucks. It is an essential component of the vehicle's HVAC (Heating, Ventilation, and Air Conditioning) system.

• 2. Core Material: High-Grade Aluminum. This provides excellent thermal conductivity for rapid cabin heating and is significantly lighter than traditional copper-brass cores.

• 3. Construction Technology: Brazed Aluminum Structure. It uses a Controlled Atmosphere Brazing (CAB) process, ensuring leak-proof joints and high resistance to the pressure and vibration typical of long-haul trucking.

• 4. Component Design: Features a high-density Fin-and-Tube design. This maximizes the surface area for heat exchange between the hot engine coolant and the cabin air.

• 5. Tank Material & Connection: Equipped with Reinforced Plastic Tanks (PA66-GF30) or Aluminum tanks (depending on the specific manufacturer variant), designed to withstand high-temperature coolant without warping.

• 6. Color and Finish: Natural Silver Finish for the aluminum core and Matte Black for the plastic end tanks.description:

    FAQ: S8710-71310 Heater Core for Hino 700

    Q1: What is the main function of this heater core? A: The heater core acts as a small radiator behind the dashboard. It circulates hot engine coolant through its aluminum tubes to provide warm air for the cabin and to defrost the windshield during cold weather.

    Q2: Is this part made of Aluminum or Copper? A: The S8710-71310 is made of high-grade Aluminum. Modern aluminum cores offer better heat dissipation, are lighter in weight, and provide superior resistance to modern engine coolants compared to older copper designs.

    Q3: Will this heater core fit all Hino models? A: No, this specific part number is designed specifically for the Hino 700 Series (Profia). To ensure a perfect fit, always cross-reference the OEM part number S8710-71310 with your vehicle’s chassis or VIN.

    Q4: What are the signs that my Hino 700 heater core needs replacement? A: Common symptoms include:

    • A sweet (antifreeze) smell inside the cabin.

    • Fog or oily film appearing on the inside of the windshield.

    • The heater is blowing cold air even when the engine is warm.

    • Coolant leaking onto the passenger side floor mat.

    Q5: How is the quality of this aftermarket part ensured? A: Our S8710-71310 units undergo 100% Helium/Air pressure testing during production to ensure there are no leaks. They are manufactured using CAB (Controlled Atmosphere Brazing) technology for maximum structural durability.

    Q6: Does the color of the unit affect its performance? A: No. The core has a Natural Silver Aluminum finish, and the tanks are typically Black. This is the standard industrial finish and does not impact the thermal efficiency or life of the product.
