Solution

1. Preparation

Gather tools and parts: OBD-II scanner, pressure tester, socket set, coolant, radiator repair kit (if applicable), safety glasses, gloves.
Ensure the engine is cool and disconnect the battery to prevent electrical issues.

2. Drain the Cooling System

Place a drain pan under the radiator.
Locate the drain plug at the bottom of the radiator and remove it to drain the coolant.
Close the drain plug securely after the coolant has been drained.

3. Remove and Inspect the Radiator

Disconnect the upper and lower radiator hoses using a hose clamp tool.
Remove any mounting bolts or clips securing the radiator to the vehicle frame.
Carefully lift the radiator out of the engine bay and inspect for visible damage or leaks.

4. Repair or Replace the Radiator

If minor damage is found, use a radiator repair kit according to the product instructions.
If the radiator is significantly damaged, replace it with a new unit:
- Install the new radiator and secure it with mounting bolts.
- Reconnect the upper and lower hoses, ensuring they are tight and secure.

5. Refill the Cooling System

Refill the radiator with the appropriate coolant mixture (check owner's manual for specifications).
Start the engine and let it run until it reaches operating temperature, checking for leaks.
Top off the coolant in the reservoir as necessary.

6. Final Checks

Reconnect the battery.
Perform a pressure test again to ensure no leaks are present.
Clean up any spilled coolant and properly dispose of used coolant.
