GENERATOR DESCRIPTION
All models are equipped with cross-flow radiators,
which provide horizontal coolant flow for improved
cooling characteristics. For specifications and us­
age, refer to the radiator charts In section 6A.
Pontiac and Tempest radiators are supported by-
insulated cradle type brackets (Fig. 1 3 - 1 ) , which
retain both the lower and upper radiator tanks. The
two upper cradles are attached to the bottomside of
the upper panel mounting assembly (Figs. 1 3 - 2 and
3) which, in turn, is fastened to the front end support
and baffle assembly.
The Firebird radiator is attached by cap screws
to the radiator support. The fan shroud on all V- 8
models is mounted in two bottom slots and secured
at the top by one center bolt.
