Ignoring these symptoms can lead to further damage or inconvenience, making timely replacement essential.

Step-by-Step Replacement Guide
Step 1: Prepare Your Workspace
Start by ensuring your workspace is clean and well-lit. Park your vehicle on a level surface and allow the engine to cool down completely before beginning the replacement process.
Step 2: Drain the Coolant
Locate the radiator drain plug and carefully drain the coolant into a suitable container. This step is crucial to prevent spills and ensure a safe working environment.
Step 3: Remove the Dashboard
Using plastic trim removal tools, carefully detach the dashboard components to access the heater core. Take note of the arrangement of wires and connectors to avoid damage during reassembly.
Step 4: Disconnect the Heater Core
Once the dashboard is removed, locate the heater core and disconnect the hoses connected to it. Be prepared for some residual coolant to spill out.
Step 5: Install the New Heater Core
Position the new heater core in place and reconnect the hoses securely. Ensure all connections are tight to prevent leaks.
Step 6: Reassemble the Dashboard
Carefully reattach the dashboard components, ensuring everything is securely fastened. Double-check all wiring and connections to avoid electrical issues.
Step 7: Refill the Coolant
Refill the radiator with the recommended coolant type for your Hyundai Elantra. Start the engine and allow it to run for a few minutes to check for leaks or issues.
