Here's a general outline of the process. Specifics will vary depending on which freeze plug is failing and the engine in your Sebring (2.0L or 2.5L). Consult a repair manual specific to your vehicle's year, model, and engine for detailed instructions and diagrams. A Haynes or Chilton manual would be invaluable.
Tools you'll likely need:
* Repair manual specific to your 1999 Chrysler Sebring Convertible: Absolutely essential.
* Socket set: Various sizes, including deep sockets.
* Ratchet and extensions: To reach tight spots.
* Pry bar or screwdriver (flat head and possibly a punch): To help remove the old freeze plug. A freeze plug installer tool is highly recommended.
* Hammer: Use carefully!
* Penetrating oil (like PB Blaster): To help loosen rusted plugs.
* New freeze plug(s): The correct size and type for your engine.
* Jack and jack stands: To safely lift and support the vehicle.
* Drain pan: To catch coolant.
* Coolant: To refill the system after the repair.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
* Optional: Freeze plug installer tool: This tool makes installing the new plug much easier and reduces the risk of damage.
General Steps (Consult your repair manual for precise locations and procedures):
1. Safety First: Disconnect the battery negative terminal. Support the vehicle securely with jack stands.
2. Drain the coolant: Locate the drain plug on the radiator and engine block (if applicable) and drain the coolant into a suitable container.
3. Access the freeze plug: This often requires removing various components like belts, pulleys, hoses, and potentially even the exhaust manifold or other parts to get proper access. Your repair manual will show exactly what needs to be removed for the specific freeze plug you're replacing.
4. Prepare the old freeze plug: Spray penetrating oil around the freeze plug's edge to help loosen it. Let it soak for a while.
5. Remove the old freeze plug: This is the most delicate part. Gently use a pry bar or screwdriver to start loosening the plug. Work carefully to avoid damaging the engine block. You may need to tap the pry bar or screwdriver gently with a hammer. A small punch can be useful for making a starting point. Avoid using excessive force.
6. Clean the area: Once the old freeze plug is removed, carefully clean the area where the new plug will go. Remove any rust, debris, or old sealant.
7. Install the new freeze plug: If you have a freeze plug installer tool, use it. This ensures even pressure during installation. If not, carefully tap the new freeze plug into place using a hammer and a block of wood (to distribute force evenly and avoid damaging the new plug or block). Don't use excessive force. The plug should seat flush with the engine block.
8. Reassemble: Carefully put everything back together in reverse order of disassembly, ensuring all bolts, nuts, hoses, and connections are properly tightened to the specifications in your repair manual.
9. Refill the cooling system: Add the correct type and amount of coolant to your vehicle's cooling system.
10. Check for leaks: Start the engine and let it run for a while. Carefully check for any leaks around the new freeze plug and other areas where you worked.
Important Considerations:
* Engine Type: The process varies depending on whether your Sebring has a 2.0L or 2.5L engine.
* Location: The location of the freeze plug significantly impacts the difficulty of replacement. Some are easy to reach, while others require significant disassembly.
* Rust: Older vehicles often have rusted freeze plugs, making removal more challenging.
* Damage: Incorrect removal or installation can damage the engine block.
Again, this is a general guide. Refer to a repair manual specific to your 1999 Chrysler Sebring Convertible for accurate and detailed instructions. If you're not comfortable performing this repair, it is highly recommended to take your vehicle to a qualified mechanic. Improper repair could result in serious engine damage.
