•
A corrugated fin type radiator has been adopted.
•
The radiator tanks are made of plastic and the
core is made of aluminum for weight reduction.
•
The down-flow direction of water inside the
radiator causes air to bleed from the cooling
system easier.
•
Four mounting rubbers are utilized to decrease
vibration.
•
The radiator has an ATF oil cooler in the lower
