Product Details

The Four Seasons Water Inlet line focuses on engine coolant components that match OE-style dimensions and sealing requirements. Part number 85399 is an aluminum inlet designed for direct replacement use in cooling system service on Hyundai Accent, Kia Rio, and Kia Rio5 models from 2006 through 2011. This water inlet is specified without a thermostat, making it the correct choice when replacing the inlet housing separately from the thermostat assembly. This part cross-references Dorman - Conduct-Tite 85399 for the same application.

Common Problems This Part Can Address

  • Coolant leakage at the inlet housing or seal surface
  • Cracked or corroded original coolant inlet housing
  • Improper sealing after thermostat housing service
  • Cooling system service on a worn Hyundai Accent, Kia Rio, or Kia Rio5 inlet
  • Replacement of an OE-style coolant inlet that no longer seals correctly

Installation Notes and Tips

Verify inlet diameter, bolt spacing, and flange dimensions before installation. Clean the mating surfaces thoroughly and inspect the gasket seat for debris or corrosion. Because the thermostat is not included, transfer or replace the thermostat separately only if your repair requires it. Confirm vehicle application by year and model before ordering; this part fits 2006-2011 Hyundai Accent, 2006-2011 Kia Rio, and 2006-2011 Kia Rio5.

Quality Assurance

Four Seasons lists this part as meeting or exceeding OEM requirements, supporting OE-style fitment and sealing performance for cooling system repair.
