Here's a general procedure. Consult your owner's manual for specific details and diagrams, as variations may exist depending on your exact model.
Tools You'll Need:
* A large drain pan (at least 5 gallons capacity)
* A wrench (likely 10mm or 13mm, check your manual) for the radiator drain petcock.
* A bucket or container for catching overflow.
* Rags or shop towels.
* Optional: Funnel to help direct coolant flow.
Procedure:
1. Locate the Radiator Drain Petcock: The radiator drain petcock is typically located at the bottom of the radiator, usually on the driver's side. It's a small valve.
2. Position the Drain Pan: Place the drain pan under the radiator drain petcock. Make sure it's positioned to catch all the coolant.
3. Open the Drain Petcock: Carefully open the drain petcock using the appropriate wrench. Turn it counter-clockwise. The coolant will begin to flow out. This may take some time.
4. Open the Radiator Cap (Optional): Some mechanics recommend also opening the radiator cap after opening the drain petcock. This can help speed up the draining process. However, always ensure the engine is completely cool before opening the radiator cap. Hot coolant under pressure can cause serious burns.
5. Wait for the Coolant to Drain: Let the coolant drain completely. This might take 15-20 minutes or more.
6. Close the Drain Petcock: Once the flow has stopped, close the drain petcock by turning it clockwise until it's tight.
7. Check for Leaks: Inspect the area around the drain petcock for any leaks.
8. Dispose of Coolant Properly: Coolant is toxic and should be disposed of properly. Check with your local waste management facility or auto parts store for proper disposal methods. Do not pour it down the drain or onto the ground.
Important Considerations:
* Coolant Type: Note the type of coolant used in your Sebring before draining. This will help you refill with the correct type. (Usually 50/50 mix of antifreeze and distilled water).
* Refilling: After draining, you'll need to refill the radiator with the correct coolant mixture. Consult your owner's manual for the correct procedure and capacity. You'll likely need to add coolant through the radiator cap and then bleed the system to remove air bubbles (see your owner's manual for this process). It's usually advisable to use a funnel to avoid spills.
* Flushing (optional but recommended): If you're doing a complete coolant flush, you'll also need to remove the lower hose from the radiator to ensure a more complete draining of the system. You would then refill and flush several times, using water initially then the correct coolant mix, before finally refilling with the correct mixture.
Remember, this is a general guide. Always refer to your owner's manual for the most accurate and detailed instructions for your specific 2002 Chrysler Sebring LX V6 2.7L model. If you're uncomfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic.
