VARIATIONS


There are two types of radiators -- downflow and crossflow:

Downflow radiators permit coolant to enter the top of the radiator and flow downward to the bottom. These radiators have cooling fins that run horizontally. The radiator cap is usually in the center of the radiator.


DOWNFLOW RADIATOR

Crossflow radiators permit coolant to enter the side of the radiator and flow across to the other side. These radiators have cooling fins that run vertically. The radiator cap is usually on one side of the radiator. Most modern engines use the crossflow radiator because of its greater efficiency.
