Hybrid Racing Replacement Coolant Switch Keep your K-swap running cool and trouble-free with the Hybrid Racing Replacement Coolant Switch. Engineered to factory-grade tolerances, this direct-fit sensor threads into any Hybrid Racing K-Swap radiator—or other M14 x 1.5 fan-switch ports—to automatically trigger your radiator fan the moment coolant temps rise above the safe limit. No more guessing, splicing, or risky toggle-switch rigs; just reliable, hands-off fan control that protects your investment lap after lap and mile after mile. Why it belongs in every K-series build OEM-style accuracy – calibrated to activate the fan at ~199 °F (92 °C) and deactivate at ~189 °F (87 °C) for consistent temperature management. Plug-and-play for K-swaps – mates directly with the factory K-series chassis harness or Hybrid Racing fan-relay kits; no repinning required. Built for abuse – brass body resists vibration, corrosion, and extreme under-hood temps common to track and boosted applications. Leak-proof sealing – pre-installed crush washer ensures a tight, drip-free fit the first time you snug it down. Compact insurance – a 5-minute upgrade that can save a head gasket, protect your tune, and keep you on track instead of on the trailer.
