Show original supplier description
The Mugen Fan Switch, part number 37760-XK5-00N0, is a high-performance thermoswitch engineered to improve engine cooling efficiency by activating the cooling fan at a lower temperature. It engages the fan at 80°C, a significant reduction from the factory's 93°C setting, helping to maintain optimal engine temperatures under demanding conditions. This premium component is designed for specific Honda applications, including those with J32A1, J32A2, and J35A engines. It is a direct fit for a wide range of Honda and Acura models, providing a crucial upgrade for enthusiasts seeking enhanced thermal management. Vehicles compatible with this fan switch include the Del Sol (1993-1997), Civic (1992-2005), Integra (1994-2001), RSX (2002-2006), S2000 (2000-2009), and TSX (2004-2008). For optimal performance and to prevent potential issues, it is recommended to use this Mugen Fan Switch in conjunction with a Mugen low-temperature thermostat. This pairing ensures that the thermostat opens at a lower temperature, complementing the fan switch's earlier activation for a more effective cooling system operation.
