This comprehensive guide will walk you through the steps on how to replace a Mitsubishi Magna heater core, ensuring you enjoy a warm and cozy ride all winter long.

1. Gather the Necessary Tools and Materials

Before you start, make sure you have all the necessary tools and materials on hand. Here’s a list of what you’ll need:

• Replacement heater core for Mitsubishi Magna
• New coolant (antifreeze)
• Radiator flush kit
• Garden hose
• Bucket
• Screwdriver set
• Pliers
• Wrench set
• Safety glasses
• Gloves

2. Prepare Your Mitsubishi Magna

Park your Mitsubishi Magna on a level surface and turn off the engine. Allow the engine to cool down completely to avoid burns. Disconnect the negative battery terminal to prevent any electrical accidents.

3. Drain the Coolant

Locate the radiator drain plug, which is usually found at the bottom of the radiator. Place a bucket underneath the drain plug to catch the coolant. Open the drain plug and allow all the coolant to drain out.

4. Remove the Heater Core Hoses

Follow the heater core hoses from the firewall to the engine compartment. Use pliers to loosen the hose clamps and disconnect the hoses from the heater core. Be careful not to spill any remaining coolant.

5. Remove the Heater Core

Locate the heater core box, which is usually situated behind the dashboard. Remove the screws or bolts that secure the heater core box to the firewall. Carefully remove the heater core from the box.

6. Install the New Heater Core

Place the new heater core in the heater core box, making sure it fits snugly. Reinstall the screws or bolts that secure the heater core box to the firewall.

7. Reconnect the Heater Core Hoses

Reattach the heater core hoses to the heater core and tighten the hose clamps securely.

8. Refill the Coolant

Mix the new coolant with water according to the manufacturer’s instructions. Pour the coolant mixture into the radiator until it reaches the “Full” mark.

9. Bleed the Cooling System

Start the engine and let it run for a few minutes with the heater turned on. Check for any leaks around the heater core hoses and connections. If there are no leaks, turn off the engine and allow it to cool down.

10. Test the Heater

Start the engine again and turn on the heater. Adjust the temperature setting to the highest level and feel the air coming out of the vents. If the air is warm, the heater core replacement was successful.

Replacing the heater core in your Mitsubishi Magna may seem like a challenging task, but by following these steps and taking the necessary precautions, you can successfully complete the job and enjoy a warm and comfortable ride during the winter months.
