Perfect Fit: Our 1-Year Test of the Hyundai/Kia Thermostat Housing Assembly

Over the past year, we’ve put the Engine Coolant Thermostat Housing Assembly (model 255002E085) to the test in our 2018 Hyundai Elantra. This direct-fit replacement part designed for 2017-2020 Elantra models (also compatible with select Kia Seltos, Forte, and Soul vehicles) has exceeded our expectations.

Installation was straightforward-the housing aligned perfectly with existing mounting points, and we didn’t need to modify anything. The quality of materials appears to match OEM standards, with no signs of degradation despite a full year of temperature cycles.

What impressed us most was the consistent engine temperature regulation. Before replacement, our Elantra had persistent cooling issues, but this assembly restored proper function immediately. The price point offers significant savings compared to dealer parts, without sacrificing durability.

For Hyundai and Kia owners needing a reliable thermostat housing replacement, we can confidently recommend this part.
