DESCRIPTION
An internal high capacity/high efficiency cooler is used on all vehicles these coolers are an oil-to-coolant type, which consists of plates mounted in the
radiator outlet tank (Fig. 36). Because the internal oil cooler is so efficient, no auxiliary oil cooler is offered. The cooler is not serviceable separately
from the radiator.
