Intercooler Intake Silicone Hose
The part number for this component is LG9704534964.

1. Basic Part Information

• Part Name: Intercooler Intake Hose / Turbocharger Connecting Hose / Silicone Hose

• Part Number: LG9704534964

• Appearance Features:

  • Color: Red (outer layer), the inner layer is typically high-temperature resistant rubber in black or dark blue.

  • Structure: The hose is curved with two metal clamps in the middle (used to secure it to rigid pipes or connectors).

  • Material: High-performance silicone, offering excellent resistance to high/low temperatures, aging, and expansion.

2. Applicable Models & Installation Position

• Applicable Models: Mainly suitable for Sinotruk HOWO light truck series, such as Hanjiang, Tongshuai, Wangpai, and other models.

• Applicable Engines: Typically used on vehicles equipped with Weichai (e.g., WP2.1, WP3N) or Sinotruk MAN technology (MC series) light-duty engines.

• Installation Position: Located between the turbocharger and the intercooler (or between the intercooler and the throttle valve), responsible for conveying high-temperature, compressed air from the turbo.

3. Main Functions & Role

• Flexible Connection: The engine generates high-frequency vibrations during operation. Rigid pipe connections can easily lead to breakage or air leaks at the joints. The silicone hose, with its good flexibility, absorbs vibrations and protects the connections.

• High Temperature & Pressure Resistance: The air discharged from the turbocharger is extremely hot (can exceed 150°C). Ordinary rubber hoses tend to age and burst. Silicone hoses maintain elasticity and strength under extreme temperatures ranging from -60°C to over 200°C.

• Sealing & Leak Prevention: Ensures that the pressurized air enters the intercooler or engine combustion chamber efficiently and without leakage, guaranteeing engine power output.
