1998 Oldsmobile Achieva heater

, ,- CAUTION:
~ Heater and radiator hoses, and other engine
1 parts, can be very hot. Don’t touch them. If you
l do, you can be burned.
Don’t run the engine
if there is a leak. If you run
1 the engine, it could lose all coolant. That could
cause an engine
fire, and you could be burned.
’ Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fan is running.
If the
engine is overheating, the fan should be running.
If it
isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ coolant 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.)
5-19

A CAUTION:
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
A CAUTION:
~
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
5-21

NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL’ (silicate-free) coolant.
If coolant other than DEX-COOL is added to the
system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs
first. Damage caused by the
use of coolant other than DEX-COOL’
is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts.
If you use this mixture,
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture, With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant,

NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater core
and other parts.
If you have to add coolant more than four times a year,
have your retailer check your cooling system.
I NOTICE: I
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
The surge tank is located on the passenger’s side of the
engine compartment.
