Replacing the Radiator

If you’re replacing the radiator, follow these steps to install the new one:

1. Install the New Radiator: Carefully lower the new radiator into place, ensuring it’s properly aligned with the mounting points.

2. Secure the Radiator Support: Secure the radiator support by reattaching the bolts or clips you removed earlier.

3. Connect the Radiator Hoses: Connect the radiator hoses to the new radiator and tighten the clamps securely.

4. Reconnect the Radiator Fan: If your car has a radiator fan, reconnect it by attaching the electrical connector and securing it to the radiator.

5. Refill the Coolant: Add new coolant to the radiator and fill the coolant reservoir to the recommended level.

6. Start the Engine: Start the engine and check for any leaks.

7. Bleed the Cooling System: Bleed the cooling system to remove any air bubbles.

8. Lower the Car: Lower the car using the jack and remove the jack stands.

9. Reconnect the Battery: Reconnect the negative battery terminal.

Final Thoughts: Beyond the Removal
