Installation Notes and Tips

Confirm thermostat requirements separately, since this inlet is supplied without a thermostat.

For fitment-specific service, confirm the vehicle year and model against the listed applications before ordering Four Seasons 85353. This part is commonly searched as a Toyota Camry water inlet, Toyota Highlander coolant inlet, or Lexus RX330 engine coolant water inlet.
