Tools You'll Need:
* Drain pan (large enough to hold several quarts of coolant)
* Socket wrench (possibly a 10mm or similar, depending on your drain petcock)
* Gloves (to protect your hands from the coolant)
* Funnel (optional, but helpful for refilling)
* New coolant (the correct type for your Malibu – check your owner's manual)
Steps:
1. Locate the radiator drain petcock: This is usually located at the bottom of the radiator, on the driver's side. It's a small valve. Your owner's manual will show you precisely where it is.
2. Position the drain pan: Place the drain pan under the radiator drain petcock to catch the coolant.
3. Open the drain petcock: Carefully open the drain petcock using the appropriate socket wrench. The coolant will begin to flow out. Be patient; it might take some time for it to drain completely.
4. Open the radiator pressure cap (optional but recommended): This will help the coolant drain more quickly and completely. Be extremely cautious when doing this, as the coolant will be hot if the engine wasn't completely cool. Let the pressure release slowly before removing the cap fully.
5. Wait for complete drainage: Once the flow slows to a trickle or stops, the radiator is mostly drained.
6. Close the drain petcock: Tighten the drain petcock securely once the coolant has stopped draining.
7. Refill the radiator: Once the radiator is drained, refer to your owner's manual for the correct type and amount of coolant to use. Use a funnel to avoid spills. Fill the radiator to the appropriate level (usually indicated by a "MAX" line or similar marking).
8. Start the engine and check for leaks: Run the engine for a few minutes to circulate the new coolant. Then turn off the engine and let it cool down completely. Carefully check for any leaks around the drain petcock and other connections.
9. Top off the coolant (if necessary): After the engine cools down, check the coolant level and top it off if needed.
Important Notes:
* Coolant is toxic: Wear gloves and eye protection to prevent contact with skin or eyes. If contact occurs, flush the area thoroughly with water and seek medical attention if necessary.
* Dispose of old coolant properly: Do not pour old coolant down the drain or onto the ground. Check with your local waste disposal facility for proper disposal methods. Auto parts stores often take used coolant for recycling.
* Consult your owner's manual: This guide provides general instructions. Your owner's manual will have specific instructions for your 2001 Chevrolet Malibu, including the location of the drain petcock, the type of coolant to use, and the proper coolant capacity.
If you are uncomfortable performing this task yourself, it is best to take your vehicle to a qualified mechanic. They have the tools and expertise to do it safely and efficiently.
