Gates CO35012 engine coolant water outlet for the 2018-2019 Hyundai Sonata 4-cylinder 2.0L and other vehicles routes coolant out of the engine at the thermostat housing. It is designed to fit and perform like the original and to give long service life.
Coolant residue around the housing, a cracked or warped plastic body, or steady coolant loss can mean the outlet is leaking. Before you replace it, rule out a loose hose clamp, a worn hose or a failed thermostat that could be behind the same coolant loss.
It is listed for a wide range of Hyundai and Kia models, including the 2018-2019 Hyundai Sonata 4-cylinder 2.0L, the 2016-2019 Kia Optima 4-cylinder 2.0L and the 2016-2018 Kia Sorento 4-cylinder 2.0L. Open the "Vehicles it fits" section to check your exact model and engine.
