How much antifreeze is in a 1989 2.9l Ford Ranger?

A 1989 Ford Ranger with a 2.9L engine typically has a coolant capacity of about 14 to 16 quarts (approximately 3.5 to 4 gallons) when including the engine and the radiator. The antifreeze-to-water ratio is generally recommended to be 50/50 for optimal performance, which means you'd need around 7 to 8 quarts of antifreeze mixed with an equal amount of water. Always check the owner's manual or a repair guide for precise specifications.
