YOLLKY Coolant Thermostat Housing Assembly for Hyundai Elantra/Kona/Veloster 2.0L — Direct Fit, Leak-Resistant

YOLLKY Coolant Thermostat Housing Assembly replaces the factory thermostat housing on compatible Hyundai Elantra, Kona, and Veloster 2.0L engines to restore coolant routing and sealing reliability.

If your vehicle shows symptoms like erratic temperature readings, coolant leaks around the thermostat area, or the housing is cracked or corroded, replacing the thermostat housing can prevent overheating and coolant loss. This YOLLKY assembly is engineered to match the original equipment form and function for selected Hyundai 2.0L models, helping you maintain proper engine coolant flow and thermostat operation without guessing on fit or orientation.

Which Hyundai models and years does this part fit?

This thermostat housing fits Hyundai Elantra 2.0L (2017–2020), Kona 2.0L (2018–2021), and Veloster 2.0L (2017–2021). Always verify compatibility by matching the OE number and engine configuration before purchase.

• Check bolt pattern, port layout, and sealing surface against the removed part

How do I confirm this is the correct replacement for my car?

Confirming fit requires checking the original equipment part number and comparing the physical configuration of your old housing to the replacement. Differences in port count, bolt locations, or sensor bosses can prevent proper installation if not matched precisely.

• Verify engine size is 2.0L and matches the vehicle's build year
• Inspect the removed housing for identical ports, bolt holes, and gasket profile
