What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 1052271) or SAE 8OW-90 GL-5 gear
lubricant.
ENGINE COOLANT
The following explains your cooling system and how to add coolant when
it is low. If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your Cadillac
will:
Give freezing protection down to -34 F (-37 C).
Give boiling protection up to 262 F (128 C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
I Let the warning lights work as they should.
1 What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 1825-M,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to GM
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use this mixture, you don’t need to add anything else.

When replacing the pressure cap, make sure it is tight.
SURGE TANK PRESSURE CAP
NOTICE:
Your surge tank cap is a 15 psi (105 kPa) pressure-type cap and
must be tightly installed to prevent coolant loss and possible
engine damage from overheating. Be sure the arrows on the cap \
line up with the
overflow tube on the radiator filler neck.
When you replace your surge tank pressure cap, an GM cap is
recommended.
THERMOSTAT
Engine coolant temperature is controlled by a thermostat in the engine
coolant system. The thermostat stops the
flow of coolant through the
radiator until the coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
