* Check your owner's manual: This is the *most* important step. The manual will specify the exact type of coolant recommended by the manufacturer for your specific 1999 Camaro engine (it might vary slightly depending on the engine). Ignore this at your own risk!
While Dex-Cool was common, some owners have successfully used other coolants, but only after careful consideration and research. Using a different coolant could lead to compatibility issues and potential damage to your engine.
If you can't find your owner's manual, a reputable auto parts store can help identify the correct coolant for your specific Camaro based on the Vehicle Identification Number (VIN). Always prioritize the information in your owner's manual.
In summary: Don't guess. Check your owner's manual first. If it specifies Dex-Cool, use a coolant that meets that specification. If it doesn't, follow the manual's recommendations precisely.
