r_ ENGINE O'VERHEATING
You will find the warning light about a hot engine on your Cadillac
instrument panel.
If Steam Is Coming From Your Engine

NOTICE:
If your engine catches fire because you keep driving with no
coolant, your vehicle can be badly damaged. The costly repairs \
would not be covered by your warranty.
IfNo Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no steam, the problem
may not be too serious. Sometimes the engine can get a little too hot
when you:
0 Climb a long hill on a hot day.
Stop after high speed driving.
0 Idle for long periods in traffic.
Tow a trailer.

If you get the overheat warning with no sign of steam, try this for a
minute or

window
as necessary.
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower
for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right
away.
If there’s still no sign of steam, you can idle the engine for two or three
minutes while you’re parked, to see if the warning stops. But then, if you
still have the warning, TURN
OFF THE ENGINE AND GET
EVERYONE OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.

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.)

NOTICE:
In cold weather, water can freeze and crack the engine, radiator, \
