What kind of coolant does a 98 chevrolete 454 use?

A 1998 Chevrolet 454 typically uses a mixture of ethylene glycol-based antifreeze and water, commonly referred to as coolant. The recommended coolant is usually a phosphate-free, extended life antifreeze, often in a 50/50 ratio with distilled water for optimal performance. Always consult the owner's manual or a professional mechanic for specific recommendations and to ensure compatibility with your vehicle.
