Lamborghini Huracan oil cooler 4S117015B

The 4S117015B is a high-performance heat exchanger specifically designed for the Lamborghini Huracán platform. This unit is primarily responsible for regulating the temperature of the 7-speed LDF (Lamborghini Doppia Frizione) dual-clutch transmission fluid. Maintaining optimal oil temperature is critical for ensuring the lightning-fast shift times and clutch longevity that the Huracán is known for.

Technical Specifications

• Compatibility: * Lamborghini Huracán LP610-4, LP580-2, and EVO models.

  • Shared platform compatibility with the Audi R8 (4S) V10.

• Core Construction: High-efficiency aluminum “plate and fin” design, optimized for maximum surface area in a compact footprint.

• Connection Type: Features precision quick-release ports for the high-pressure oil lines and coolant hoses.

• System Integration: Operates as a liquid-to-liquid cooler, utilizing the car’s main engine coolant to draw heat away from the transmission oil.

Key Performance Features

• Thermal Stability: Engineered to handle the extreme heat spikes generated during “Thrust Mode” (launch control) starts and aggressive downshifting in Corsa mode.

• Compact Lightweight Design: Specifically shaped to fit within the dense packaging of the Huracán’s mid-engine bay without compromising airflow to other components.

• Durability: Pressure-tested to withstand the high-flow rates required by the LDF gearbox’s internal hydraulic pumps.

Professional Installation & Maintenance

When replacing the 4S117015B, it is vital to follow these professional steps:

1. Seal Replacement: Always use new O-rings (typically Viton or high-temp rubber) on the oil line connectors to prevent leaks under high pressure.

2. Fluid Level Check: After installation, the transmission fluid level must be re-checked at a specific temperature (usually between 35°C and 45°C) using diagnostic software to ensure the new cooler is fully primed.

3. Debris Inspection: If the previous cooler was replaced due to a transmission failure, the lines must be thoroughly flushed to ensure no metal shavings remain to contaminate the new unit.
