Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical issues.
Allow the engine to cool completely before starting work.

2. Drain Cooling System

Place a drain pan under the radiator.
Open the radiator drain valve and allow coolant to fully drain.
Close the drain valve once the coolant has been drained.

3. Remove Radiator

Disconnect the upper and lower radiator hoses using a hose clamp tool.
Remove any electrical connectors or sensors attached to the radiator.
Unbolt the radiator from its mounts using a socket wrench.
Carefully lift the radiator out of the engine bay.

4. Inspect and Repair

Check for cracks, corrosion, or pinholes in the radiator.
If the damage is minor, clean the area around the leak and apply a radiator sealant as per the product instructions.
For significant damage, replace the radiator with a new one.

5. Install New or Repaired Radiator

Place the radiator back into the engine bay and secure it with bolts.
Reconnect electrical connectors and sensors.
Reattach the upper and lower radiator hoses, ensuring clamps are tight.

6. Refill Cooling System

Open the radiator cap and fill the radiator with a mixture of coolant and distilled water (50/50 ratio).
Fill the overflow reservoir to the recommended level.
Start the engine and let it run until it reaches operating temperature, checking for leaks.

7. Final Checks

After the engine has cooled, check coolant levels and top off as needed.
Reconnect the negative battery terminal.
