For a 2007 Buick Lacrosse, it is recommended to use a dex-cool antifreeze, which is a specific type of coolant formulated for GM vehicles. Look for a 50/50 mix of dex-cool antifreeze and distilled water, or a pre-mixed version. Ensure it meets the GM specification of GM 6277M. Always check your owner's manual for specific recommendations and guidelines.
