Important Considerations:
* Check your owner's manual: The best source of information is always your owner's manual. It will specify the recommended type and concentration of antifreeze.
* Color is not a reliable indicator: The color of antifreeze varies by manufacturer and doesn't indicate its type or compatibility.
* Flush and refill: When changing antifreeze, it's best to flush the cooling system thoroughly to remove old, degraded antifreeze.
* Distilled water: Always use distilled water, not tap water, to mix with antifreeze. Tap water contains minerals that can damage the cooling system.
Using the wrong antifreeze can severely damage your engine, so double-checking your owner's manual and using a reputable brand are vital.
