Tools and Materials You'll Need:
* New coolant: Use the correct type and concentration specified in your owner's manual (usually a 50/50 mix of coolant and distilled water). Failure to use the correct coolant can damage your engine.
* Distilled water: Tap water contains minerals that can damage your cooling system.
* Drain pan: Large enough to hold several gallons of coolant.
* Wrench: To remove the drain plug (size will vary depending on your specific vehicle - check your owner's manual).
* Funnel: To help pour coolant into the radiator.
* Hose clamp pliers (optional): If you're replacing hoses.
* Gloves: Protect your hands from the hot coolant.
* Safety glasses: Protect your eyes from splashes.
* Cooling system flush kit (optional but recommended): These kits help ensure thorough cleaning of the system. They often include a cleaner and a conditioner.
* Pressure tester (optional but recommended): Checks for leaks in the system after filling.
Procedure:
1. Safety First: Let the engine cool completely before starting. Hot coolant can cause severe burns.
2. Locate Drain Plug: Consult your owner's manual to find the location of the radiator drain plug and engine block drain plug (if applicable). Some systems only have a radiator drain.
3. Drain the Coolant: Place the drain pan under the drain plug(s). Carefully open the drain plug(s) to allow the old coolant to drain completely. This may take some time.
4. Flush the System (Optional, but highly recommended):
* Using a Flush Kit: Follow the instructions provided with your chosen flush kit. This typically involves adding the cleaner to the system, running the engine for a specified time, then flushing with water.
* Without a Flush Kit: Fill the radiator with distilled water. Start the engine and let it run for about 10-15 minutes, with the heater turned on to circulate water through the entire system. Drain the water, and repeat this process at least once more until the drained water runs relatively clear.
5. Refill the System: Once the flushing is complete (or if skipping the flush), carefully add the pre-mixed coolant to the radiator using the funnel. Add coolant until the radiator is full, but don't overfill.
6. Bleed the Air: This is crucial to prevent overheating. There are usually bleed valves (small screws) located on the engine or the heater core. Consult your owner's manual for their location. Open the bleed valves and squeeze the upper radiator hose a few times to help release trapped air. Close the valves once coolant flows freely.
7. Check Coolant Level: Add more coolant as necessary to bring the level up to the proper mark (usually indicated on the radiator or overflow tank). The level might drop a bit as the system cools.
8. Run the Engine: Start the engine and let it run for about 15-20 minutes, keeping an eye on the temperature gauge. Check for any leaks. Top up coolant if necessary.
9. Check for Leaks: Carefully inspect the system for leaks. Use a pressure tester if available for a more thorough check.
10. Final Check: Once the engine has cooled down, check the coolant level again and add coolant if necessary.
Important Notes:
* Consult Your Owner's Manual: This is the most reliable source of information for your specific vehicle. The exact procedures and specifications may vary slightly.
* Coolant Type: Use the correct type of coolant recommended in your owner's manual. Mixing different types of coolant can lead to problems.
* Disposal: Dispose of the old coolant properly. Most auto parts stores accept used coolant for recycling.
This procedure provides a general guideline. Always refer to your owner's manual for specific instructions and recommendations for your 2000 Chrysler Sebring Convertible. If you're not comfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic.
