Radiator Fan Thermo Switch for Honda Cooling System ️

This OEM-style coolant temperature switch controls the radiator fan so your engine keeps the right working temperature. It’s small, tough, and vital for daily reliability. When coolant heats up to factory-set range (about 93°C),the switch closes and powers the fan; when it cools down, it opens to stop the fan. Simple, mechanical, and dependable.

Why you need this part ✅

Without correct fan control, heat builds up fast. This switch prevents overheating in traffic, helps the A/C condenser, and stabilizes engine temperature for clean combustion and longer gasket, hose, and oil life.

How it works ⚙️

Mounted in the thermostat housing or radiator, the two-pin thermo switch senses coolant temperature. At the set point it completes the circuit to the fan relay. No complex programming—just precise on/off at the right temperature.

What happens if it’s faulty

  • Fan never turns on: overheating, boiling coolant, warped head risk
  • Fan stuck on: long warm-up, extra noise, battery load
  • Intermittent operation: unstable temperature, weak A/C at idle

Tech tips for install ️

  • Replace sealing washer, clean threads, and torque to spec
  • Top up coolant and bleed air after install
  • Test by warming engine or briefly bridging the connector to verify fan/relay
