Radiator Support And Mounting Parts - Pontiac Grand Prix Service Manual

RADIATOR SUPPORT AND MOUNTING PARTS
GENERAL DESCRIPTION
All models are equipped with cross-flow radiators,
which provide horizontal coolant flow for improved
cooling characteristics. For specifications and usage,
refer to the radiator charts in Section 6A.
Pontiac, Grand Prix and Tempest V-8 radiators are
supported by insulators which are. cradled in the fan
shroud (Figs. 13-1 and 2). The fan shroud is firmly
attached to the support and baMe assembly. Tempest
6 cylinder radiators are supported by insulatedcradle
type brackets (Fig. 13-3), which retain both the lower
and upper ends of the radiator tanks. The two upper
cradles are attached to the bottomside of the upper
panel mounting assembly (Fig. 13-2) which, in turn, is
fastened to the front end support and baffle assembly.
NOTE: Tempest 6 cylinder rqdiator is held at bottom by
two cradle type brackets and insulators secured to
support and baffle assembly (Fig. 13-3).
REPLACE
1. Replace radiator assembly by reversing the above
procedure, making sure the lower insulators are
properly located in the radiator bottom tank recesses.
2. Torque all upper panel mounting screws to 12 Ib. ft.,
all fan shroud to upper panel mounting screws to 7 Ib.
ft., and all cradle
type
bracket attaching screws to 12
lb. ft.
3. Refill radiator with enough coolant to ensure all
weather corrosion protection.
The Firebird radiator is attached by cap screws and
FIREBIRD
insulating nuts on one side to the radiator support. The
fan shroud on all V-8 models is mounted in two
