a.
Radiator Construction.
Automobile, truck, and tractor radiators consist of two water tanks (upper
and lower) joined by a core which does the actual cooling. Water from the
cylinder block usually enters the upper tank through the inlet, flows
through the core, and leaves by the lower tank. An overflow pipe in the
upper tank carries away excess steam or water. In the radiator assembly,
cast metal tanks are bolted to the side members. Gaskets between the tanks
and core make a watertight connection. This type of rigid radiator
construction is usually used on heavyduty trucks and tractors. Figure 34
illustrates stamped metal radiators that are formed by soldering drawn or
stamped metal tanks to the radiator core. The side members are straps of
steel soldered to upper and lower tanks.
