Where is the coolant temperature sensor located on the Hyundai Elantra?

Modern Elantra coolant temperature sensor is located at the front end of the engine water inlet pipe. Most vehicles use water-cooled engines, which rely on coolant circulating continuously within the engine for heat dissipation, requiring a coolant temperature sensor. The engine coolant needs to be replaced regularly. If not changed for a long time, the coolant's freezing point will rise and boiling point will decrease, affecting normal engine operation. In water-cooled engines, the coolant follows two circulation paths: major circulation and minor circulation. When the engine is first started and at low temperature, the coolant performs minor circulation to help the engine warm up quickly. During minor circulation, the coolant bypasses the radiator. When the engine reaches normal operating temperature, the coolant switches to major circulation to maintain optimal engine temperature.
