Subaru engines are water-cooled. The Subaru EN engine, which was introduced in 1988, replaced the air-cooled EK series engine and was modified to be a water-cooled engine. All of Subaru’s six-cylinder engines are also liquid-cooled. The cooling system in a Subaru engine works by circulating liquid coolant through passages in the engine block and heads to absorb heat from the engine.
