Installation Notes and Tips

Verify the housing shape, inlet port diameter, and bolt spacing before installation. Because the thermostat and gasket or seal are not included, transfer or replace those components as needed during service. Clean the mating surfaces thoroughly and inspect the coolant passages, hose connections, and fasteners before reassembly. Confirm fitment for your exact year and engine configuration on Hyundai Elantra, Tucson, Tiburon, and Kia Soul, Sportage, Spectra, or Spectra5 applications.
