What color antifreeze do you put in a lEXUS 300 coup?

For a Lexus SC 300, it's recommended to use a pink or red coolant that meets Toyota's specifications, typically a long-life ethylene glycol-based antifreeze. This is often referred to as Toyota's Super Long Life Coolant (SLLC). Always check your owner's manual for specific recommendations and ensure proper dilution with distilled water if needed.
