Radiator Fan Switch Sensor for Yamaha YFM400FA 2003‑2006, Durable Metal Water Temperature Sensor Replacement

Radiator Fan Switch Sensor for Yamaha YFM400FA 2003‑2006, Durable Metal Water Temperature Sensor Replacement Description

Radiator Fan Switch Sensor replacement designed to restore reliable temperature control in compatible ATV cooling systems. This metal temperature sensor senses coolant temperature with accuracy and signals the radiator fan to engage, helping maintain stable engine temperature during operation. Key benefits Accurate temperature sensing for reliable fan control and consistent engine cooling. Direct replacement with original OE reference for straightforward fitment and compatibility. Durable metal construction resists temperatures and corrosion for longer service life. Simple swapout replacement that can resolve overheating or fan cycling issues when the original sensor fails. What it does Monitors the coolant temperature and activates the radiator fan heatsink as needed to regulate engine temperature. Uses the referenced OE design and specifications to match original performance and electrical characteristics. Compatibility OE number: 4BA 82560 00 00 (molded and designed on original data) Fits for 400 YFM400FA 4X4 model years 2003 to 2006 Fits for 400 YFM400FAH 4X4 model years 2004 to 2006 Please double check your vehicle part number before ordering; matching information is provided for reference. Material and performance Constructed from metal material for heat resistance and strength. Designed for accurate temperature sensing to ensure timely fan engagement and stable cooling performance. Package contents 1 x Sensor Typical applications and use scenarios a failed or intermittent radiator fan switch to stop overheating and restore normal fan operation during trail or utility use. Preventive replacement during routine cooling system maintenance before the riding season to reduce the risk of heatrelated failures. Troubleshooting intermittent fan cycling or coolant temperature spikes by swapping in a known good sensor to confirm operation. Notes Verify the OE number 4BA 82560 00 00 and your vehicle model year before to ensure proper fitment. If you are unsure whether this sensor matches your equipment, check the existing part number before buying to avoid unnecessary returns.
