1994 CADILLAC FLEETWOOD cooling

TMLER TOWING PACMGE (OPTION)
If your Fleetwood is equipped with either V92 or V4P package, you can
increase your vehicle's trailer towing capability to
5,000 pounds (2270 kg)
or 7000 lbs. (3178 kg). To determine which package you have, see the
Service Parts Label located on the underside
of the trunk lid. These
packages include a trailering harness located
in the trunk, heavy-duty
engine and transmission cooling.
Also included are heavy-duty front and
rear springs, 2.93:l rear axle ratio and Eagle
GA P235/70R15 tires.

ELECTRONIC CLIMTE CONTROL
With this system you can control the ventilation, heating and air
conditioning in your vehicle automatically by setting the desired
temperature. The digital screen displays the outside temperature, the
I
inside temperature setting, fan speed, and the ECC selection you have
selected.
OUT TEMP (Outside Temperature)
Push this to get the outside temperature. Push it again to return to the
regular system display.
TEMP (Inside Temperature)
Sets the interior temperature you want. Press the lower portion (blue
arrow) to lower the inside temperature setting. Press the upper portion
(red arrow) to raise the temperature setting. Once you set the
temperature, the system will automatically maintain the set temperature.
You can change the temperature from 65 F (18 C) to 85 F (29 " C), one
degree at a time. You may also choose
60 " F (16 " C), for maximum
cooling, and 90°F
(33 "C), for maximum heating, the fan will stay on high
speed unless you select a different speed.
In maximum heating most of
the air will
flow out the heater ducts. In maximum cooling, the system will
recirculate the air inside your vehicle instead of pulling air from outside.

HILL AND MOUNTMN ROADS
Driving on steep hills or mountains is different from driving in flat or
rolling terrain.
If you drive regularly in steep country, or if you’re planning to visit there,
here are some tips that can make your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transmission. These parts can work
hard on mountain roads.
Know how to go down hills. The most important thing to know is this:
let your engine do some
of the slowing down. Shift to a lower gear
when you go down a steep or long hill.

Engine Cooling When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as;
Climbing grades steeper than 4% at ambient temperatures above
90’Fahrenheit (32O Celsius)
with a loaded vehicle and trailer.
0 Stopping after high-speed driving.
0 Idling for long periods in stop and go traffic.
If the “TEMP” warning light comes on, pull
to the side of the road as
soon as it is safe to do
so. When the vehicle is at a complete stop, shift the
transmission selector to P (Park) and allow the engine to idle. If your
Electronic Climate Control system is on, shut it
off. Do not turn off the
engine or increase engine speed above a normal idle. Within
two or three
minutes the system should cool sufficiently to allow A/C operation to
resume. At that time resume driving at a reduced speed. Return to
normal driving after
10 minutes if the “TEMP” warning light is not
displayed.
Maintenance when Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer.
See the Maintenance Schedule for details. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, engine drive belt, cooling system, and
brake adjustment. Each of these is covered in this manual. The Index will
help you find them quickly. If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to
see that all hitch attaching nuts and bolts are tight.

r COOLING SYSTEM
When you decide it’s safe to lift the hood, here’s what you’ll see:
A. Coolant surge tank
B. Electric engine fans (If equipped)
If the coolant inside the coolant surge tank is boiling, don’t do anything
else until it cools down.
225

I
The coolant level should be at or above the seam inside the surge tank. If
it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cooling system.
NOTICE:
Engine damage from running your engine without coolant isn’t \
covered
by your warranty.
If there seems to be no leak, check to see if the electric engine fans are
running.
If the engine is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

r_ How to Add Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t visible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is cool
before you do it. (See “Engine Coolant” in the Index for more
information about the proper coolant mix.)
227

1. You can remove the coolant surge tank pressure cap when the cooling
system, including the coolant surge tank pressure cap and upper
radiator hose, is
no longer hot.
Turn the pressure cap
slowly about
one-quarter turn to
I the left and then stop.
-
~
If you hear a hiss, wait for that to stop. A hiss means there is still some
pressure left.
2. Then keep turning the pressure cap slowly, and remove it.
3. Fill the coolant
surge tank with
the proper
mix, up
to the base of the
filler neck.
