Does antifreeze go in a diesel engine?

Yes, antifreeze is used in diesel engines to prevent the engine from freezing in cold weather. Antifreeze is a mixture of water and chemicals, such as ethylene glycol or propylene glycol, which lower the freezing point of water. This is important because diesel engines operate at much higher temperatures than gasoline engines, and the coolant needs to be able to withstand these high temperatures without freezing. Antifreeze also helps to protect the engine from corrosion and overheating.
