2007 SATURN RELAY coolant temperature

3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transaxle Fluid,” earlier in this section.
4. When the correct uid level is obtained, push
the dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs rst,
if you add only DEX-COOL
®extended life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have a
problem with engine overheating, seeEngine
Overheating on page 435.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning messages and gages work
as they should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.

{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. Do not spill
coolant on a hot engine.
Occasionally check the coolant level in the
radiator. For information on how to add coolant to
the radiator, seeCooling System on page 438.
Radiator Pressure Cap
Notice:The radiator cap on your vehicle
is a pressure-type cap and must be tightly
installed to prevent coolant loss and possible
engine damage from overheating. Be sure
the cap is properly closed.
SeeEngine Compartment Overview on page 422
for more information on location.
Engine Overheating
You will nd an engine coolant temperature gage
on your vehicle’s instrument panel. SeeEngine
Coolant Temperature Gage on page 228.
Your vehicle may also have an ENGINE
COOLANT HOT message displayed in the Driver
Information Center (DIC). SeeDIC Warnings
and Messages on page 241.

If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. If your air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
3. If you are in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving — DRIVE (D) or THIRD (3).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not come
back on, you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there is still no sign of steam, idle the engine
for three minutes while you are parked. If you still
have the warning, turn off the engine and get
everyone out of the vehicle until it cools down.
Also, see “Overheated Engine Protection
Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
This emergency operating mode allows your
vehicle to be driven to a safe place in an
emergency situation. If an overheated engine
condition exists, an overheat protection mode
which alternates ring groups of cylinders helps
prevent engine damage. In this mode, you
will notice a signicant loss in power and engine
performance. The temperature gage will
indicate an overheat condition exists. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life
system. SeeEngine Oil on page 423.

(g)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(h)Change automatic transaxle uid and lter if
the vehicle is mainly driven under one or more of
these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i)Drain, ush, and rell cooling system. See
Engine Coolant on page 432 for what to
use. Inspect hoses. Clean radiator, condenser,
pressure cap, and ller neck. Pressure test
the cooling system and pressure cap.
(j)Check system for interference or binding and
for damaged or missing parts. Replace parts
as needed. Replace any components that have
high effort or excessive wear. Do not lubricate
accelerator or cruise control cables.(k)A uid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the uid level checked.
Add uid if needed.
(l)If you drive regularly under dusty conditions,
the lter may require replacement more often.
(m)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
Owner Checks and Services
These owner checks and services should be
performed at the intervals specied to help ensure
the safety, dependability, and emission control
performance of your vehicle. Your Saturn retailer
can assist you with these checks and services.
Be sure any necessary repairs are completed at
once. Whenever any uids or lubricants are added
to your vehicle, make sure they are the proper
ones, as shown inRecommended Fluids and
Lubricants on page 530.
