1994 CADILLAC FLEETWOOD cooling

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.

Adding Coolant
Your cooling system when hot is under a lot of pressure. If the “LOW
COOLANT” light should appear, you need to add coolant. If it doesn’t
the coolant
is at the proper fill level.
To Check Coolant
When your engine is cold, the coolant level should be at the base of the
filler neck.
To Add Coolant
If you need more coolant, add the proper mix at the surge tank, but only
when the engine is cool.

The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight
aim, bumper height, vehicle ground clearance, and tire or tire \
chain clearance to the body and chassis.
