Solution

1. Preparation

Tools Required: Socket set, coolant catch pan, OBD-II scanner, multimeter
Allow the engine to cool before beginning work to avoid burns.

2. Coolant Level Check

Locate the coolant reservoir and remove the cap.
If coolant is low, fill it with the recommended coolant type (typically a 50/50 mix of water and antifreeze).
Replace the cap securely.

3. Inspect and Replace Radiator Fans

Disconnect the battery to prevent electrical shorts.
Remove the radiator fan assembly by unscrewing the mounting bolts.
Test the fan motor using a multimeter to check for proper operation.
If faulty, install a new fan assembly.
Reconnect the battery and ensure fan operation.

4. Check and Repair Leaks

Inspect the radiator and hoses for leaks using the coolant catch pan to collect any dripping fluid.
Replace any damaged hoses or a leaking radiator.
Tighten any loose connections to ensure a proper seal.

5. System Flush and Refill

If the coolant is dirty or contaminated, perform a coolant flush.
Drain the old coolant from the radiator by removing the drain plug.
Flush the system with clean water until it runs clear.
Refill with the manufacturer-recommended coolant.
