9. Run engine, with radiator cap removed,
until normal operating temperature is
reached.
10. Check and adjust coolant to proper level
and install radiator cap. Make certain red
stripe on cap lines up with overflow tube.
It is the owner's responsibility to keep the
freeze protection at a level commensurate with
the temperatures which may occur in the area of
vehicle operation.
• Maintain cooling system freeze protection at
_40°F. or below to ensure protection against
corrosion and loss of coolant from boiling,
even though freezing temperatures are not
expected.
• Add ethylene glycol base coolant that meets
GM Specification 1899-M when coolant
additions are required because of coolant
loss or to provide additional protection
against freezing at temperatures lower than
-40·F.
NOTE: Alcohol or methanol base coolants
or plain water are not recommended for
your Cadillac at any time.
THERMOSTAT
The cooling system is protected and controlled
by a thermostat installed in the engine coolant
outlet to maintain a satisfactory operating tem-
perature of the engine. This thermostat is de-
signed for continuous use through both winter
and summer and need not be changed seasonally.
When replacement is necessary, Delco Parts are
recommended.
Rear axle
or
final drive
lubricant
Every 4 months or 6,000 miles, whichever occurs
first, check lubricant level and add lubricant, if
necessary, to fill to level of filler plU9 hole_ Use
SAE 90 GL-5 Gear Lubricant. In areas with
extreme cold weather or in vehicles normally oper·
ated in Canada, use SAE 80 GL-5 Gear Lubricant.
Clean area around filler hole before removing
filler plug and take care to prevent dirt from
entering hole and contaminating the lubricant.

Power
steering
system
Check the fluid level in the pump reservoir at each
engine oil change period. Add GM Power Steering
Fluid (or DEXRON Automatic Transmission
Fluid) as necessary to bring level into proper range
on filler cap indicator depending upon fluid tem-
perature.
If
at operating temperature (approximately
15lf'F - hot to the touch). fluid should be
between "HOT" and "COLD" marks. If at room
temperature (approximately lO·FI, fluid should
be between "ADD" and "COLD" marks. Fluid
does not require periodic changing. Fasten cap
securely after checking.
