AUTOMATIC TRANSAXLE FLUID
When to Check and Change:
A good time to check your automatic transaxle fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can
be a little difficult, you may choose to have
this done at a Cadillac dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you
could get a false reading on the dipstick.

NOTICE:

Wait at least 30 minutes before checking the transaxle fluid level if you
have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is
180’F to 200°F (82°C to 93OC).
Get the vehicle warmed up by driving about 15 miles (24 km) when
outside temperatures are above
50°F (10” C). If it’s colder than 50’F
(10 C), you may have to drive longer.
To check the fluid level:
0 Park your vehicle on a level place.
Place the shift lever in “P” (Park) with the parking brake applied.
With your foot on the brake pedal, move the shift lever through each
gear range, pausing for about three seconds in each range. The\

How to Add Fluid:
Refer to the Maintenance Schedule to determine what kind of transaxle
fluid to use. See “Recommended Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper fluid to bring the
level into the cross-hatched area on the dipstick. It doesn’t take much
fluid, generally less than a pint. Don’t overfill. We recommend you use
only fluid labeled DEXRON@-IIE, because fluids with that label are

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) .
0 Give boiling protection up to 262OF (128O C) .
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
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

Engine Coolant Supplement (sealer) with any complete coolant change.
If you use these, you don’t need to add anything else.
Adding only plain water to your cooling system can be
dangerous. Plain water, or some other liquid like alcohol, can
boil before the proper coolant mix will. Your vehicle’s cwlant
warning system is set for the proper coolant mix With plain
water or the wrong mix, your engine could get too hot but you
wouldn’t get the overheat warning. Your engine could catch fire
and you or others could be burned. Use a 50/50 mix of dean
water and a proper anti€reeze,
