What You’ll Need 🛠️

Before you get started, you’ll need to gather a few tools and materials. Here’s what you’ll need:

  • A drain pan

Step-by-Step Guide 📝

Here are the steps you need to follow to change the coolant in your 2011 Subaru Legacy:

Step 1: Locate the Radiator Drain Plug 🚽

The first step is to locate the radiator drain plug. This is usually located on the bottom of the radiator and can be accessed from underneath the car.

Step 2: Remove the Radiator Drain Plug 🛠️

Once you’ve located the drain plug, use a socket wrench to loosen it and remove it from the radiator. Make sure you have your drain pan underneath the radiator to catch the coolant as it drains out.

Step 3: Drain the Coolant 💧

Allow the coolant to drain completely from the radiator into the drain pan. This may take a few minutes, so be patient. Once the coolant has finished draining, replace the drain plug and tighten it securely.

Step 4: Refill with Water 💦

Next, refill the radiator with distilled water. You can use a funnel to make it easier to pour the water into the radiator.

Step 5: Run the Engine 🚗

Once you’ve refilled the radiator with water, start the engine and let it run for a few minutes. This will help to circulate the water throughout the engine and flush out any remaining coolant.

Step 7: Refill with New Coolant 🆕

Once you’ve drained the water, it’s time to refill the radiator with new coolant. Make sure you use the correct type of coolant for your Subaru Legacy. You can find this information in your owner’s manual or by consulting with a mechanic.

Step 8: Run the Engine Again 🚗

Start the engine again and let it run for a few minutes to circulate the new coolant throughout the engine.

Step 9: Check the Coolant Level 🔍

After you’ve run the engine for a few minutes, turn it off and allow it to cool completely. Then, check the coolant level in the radiator and add more coolant if necessary.

Step 10: Dispose of Old Coolant Properly ♻️

Make sure you dispose of the old coolant properly. Do not pour it down the drain or into the ground. Check with your local waste management facility to find out how to dispose of it safely.
