COOLING SYSTEM CAP, COOLANT RESERVE TANK CONSTRUCTION [LF]
• A low-pressure type cap has been adopted for the cooling system. 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.
