Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery for safety.

2. Inspect and Remove the Heater Core

Remove the dashboard or trim panels as necessary to access the heater core.
Disconnect the heater core inlet and outlet hoses.
Remove mounting screws and carefully pull the heater core out of its housing.

3. Inspect and Repair/Replace

Examine the heater core for leaks or corrosion.
- If leaking:
  - Replace the heater core with a new one.
- If not leaking:
  - Inspect the hoses for wear and replace if necessary.
Reinstall the heater core in the housing by reversing the removal steps.

4. Refill Cooling System

Reconnect the heater hoses and ensure all connections are tight.
Refill the cooling system with the recommended coolant type and mixture (usually a 50/50 mix of antifreeze and distilled water).
Bleed the cooling system to remove air pockets.

5. Reassemble

Reinstall the dashboard or trim panels.
Reconnect the battery.
