• A low-pressure type cap has been adopted for the cooling system cap. It is installed on the coolant reserve tank to improve serviceability when adding engine coolant and bleeding air.
• A degassing type coolant reserve tank has been adopted, to integrate the simple airtight sub-tank and the air/water separating tank, improving the air/water separating function. The integrated and large-size degassing tank consists of a labyrinth structure with internal barriers to lengthen the distance to the outlet and reduce the flow speed to lengthen the time the engine coolant has to accumulate, improving the air/water separation function.
