Solution

1. Preparation

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

2. Drain Coolant

Place a drain pan under the radiator.
Open the radiator drain valve or remove the lower hose to drain coolant completely.
Dispose of old coolant according to local regulations.

3. Remove the Radiator

Remove the radiator support brackets using a socket set.
Disconnect the upper and lower radiator hoses by loosening the clamps.
Disconnect any electrical connectors for the cooling fans.
Unscrew the mounting bolts securing the radiator and carefully lift it out.

4. Inspect and Replace

Inspect the old radiator for visible cracks or holes.
If damaged, install the new radiator by reversing the removal steps.
Ensure all hoses and connectors are secured and sealed properly.

5. Refill Coolant

Close the drain valve or reattach the lower hose.
Refill the radiator with a 50/50 mixture of coolant and distilled water.
Run the engine with the radiator cap off to purge any air from the system.

6. Finish Up

Replace the radiator cap securely.
Reconnect the negative battery terminal.
Check for leaks around all connections after running the engine for a few minutes.
