Safety First:
* Let the engine cool completely. Working on a hot engine is incredibly dangerous. Wait several hours after driving before starting.
* Wear safety glasses and gloves. Coolant is corrosive.
* Work in a well-ventilated area.
* Have the correct coolant type ready. Check your owner's manual for the recommended type (usually a 50/50 mix of coolant and distilled water).
Tools and Materials:
* Large drain pan: To catch the old coolant.
* Wrench(es): To remove the drain plug(s) (size will vary depending on your car – check your owner's manual or look at the plugs beforehand).
* Hose and adapter: To connect to the radiator drain and fill points. You might need a hose to reach your drain pan.
* Garden hose: To flush the radiator.
* Funnel: To add the new coolant.
* New coolant: The correct type and amount for your Camaro (check your owner's manual).
* Shop rags or paper towels: For cleanup.
Procedure:
1. Locate the radiator drain plug: This is usually located at the bottom of the radiator, on the passenger side. Consult your owner's manual if you can't find it.
2. Place the drain pan under the drain plug: Position it to catch all the old coolant.
3. Open the radiator cap: This releases pressure and allows for easier draining. Do this *after* positioning the drain pan.
4. Open the drain plug: Slowly unscrew the plug to allow the coolant to drain into the pan. Be cautious as it will be hot if the engine wasn't completely cool.
5. Once drained: Allow the radiator to drain completely. This may take some time.
6. Close the drain plug: Tighten it securely, but don't overtighten.
7. Connect the garden hose: Attach the hose to the upper radiator hose (the hose coming from the engine to the radiator) using an appropriate adapter if needed. Route the other end into a drain.
8. Turn on the garden hose: Run water through the radiator until the water runs clear from the drain plug. This step helps remove any remaining debris or old coolant.
9. Turn off the garden hose: Disconnect the garden hose.
10. Reconnect the upper radiator hose: If you had to remove it for the flush.
11. Open the radiator cap: Carefully open the radiator cap.
12. Fill the radiator: Use a funnel to carefully add the new coolant mix to the radiator. Refer to your owner's manual for the correct amount.
13. Run the engine: Run the engine for 10-15 minutes, allowing the thermostat to open and circulate the new coolant throughout the system. Monitor the coolant level and add more as needed.
14. Check for leaks: Inspect the radiator and hoses for any leaks after running the engine.
15. Top off the coolant: Once the engine has cooled, check the coolant level and top it off to the proper level. Remember to use the proper coolant mix.
Important Considerations:
* Block Drains: Some systems also have drain plugs on the engine block. Check your owner's manual to see if yours does, and repeat the drain and flush process for these as well. This would improve the thoroughness of the flush.
* Radiator Flush Chemicals: You can use a radiator flush chemical to help loosen up sediment and debris, but follow the manufacturer's instructions carefully. Usually, you add the chemical, run the engine, then drain and flush with water.
* Pressure Testing: For a more comprehensive check of your cooling system, consider a pressure test to identify any leaks that might not be immediately apparent.
