Engine Oil
For diesel engine vehicles, see“Engine Oil”in the Duramax dieselsupplement.
To e n s u r e p r o p e r e n g i n eperformance and long life, carefulattention must be paid to engine oil.Following these simple, butimportant steps will help protectyour investment:
.Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.
.Check the engine oil levelregularly and maintain theproper oil level. See“CheckingEngine Oil”and“When to AddEngine Oil”in this section.
.Change the engine oil at theappropriate time. SeeEngine OilLife System0221.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.
Checking Engine Oil
Check the engine oil level regularly(every 650 km (400 mi), especiallyprior to a long trip. The engine oildipstick handle is a loop. SeeEngine Compartment Overview0218for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center(DIC) message displays, check theoil level.
Follow these guidelines:
.To g e t a n a c c u r a t e r e a d i n g , p a r kthe vehicle on level ground.Check the engine oil level afterthe engine has been off for atleast two hours. Checking theengine oil level on steep gradesor too soon after engine shutoffcan result in incorrect readings.Accuracy improves when

Caution (Continued)
fluid could come out and fall on
hot engine parts or exhaust
system parts, starting a fire. Too
little fluid could cause the
transmission to overheat. Be sure
to get an accurate reading if
checking the transmission fluid.
Wait at least 30 minutes with theengine off, before checking thetransmission fluid level if the vehiclehas been driven:
.In hot weather, when outsidetemperatures are above 32 °C(90 °F).
.The vehicle is heavily loaded.
.At high speed for quite a while inhot weather.
.In heavy traffic and hot weather.
.While pulling a trailer.
After driving under these conditions,ahotcheckcanbeperformed.Thefluid should be hot, which is 71 °C to93 °C (160 °F to 200 °F).
Acoldfluidlevelcheckcanbeperformed after the vehicle hasbeen sitting for eight hours or morewith the engine off, but this is usedonly as a reference. Let the enginerun at idle for five minutes if theoutside temperature is between 15 °Cto32°C(60°Fto90°F).Shouldthe fluid level be low during this coldcheck, the fluid must be checkedwarm or hot before adding fluid.If the outside temperature is colderthan 15 °C (60 °F) or hotter than 32 °C(90°F),acoldcheckcannotbeperformed.
Awarmfluidlevelcheckcanbeperformed by driving the vehicleunder lightly loaded conditions andoutside temperatures between 10 °Cto 27 °C (50 °F to 80 °F). Thevehicle should be driven for at least24 km (15 mi) before performing awarm check. Checking the fluidwarm or hot will give a moreaccurate reading of the fluid levelthan a cold check.
Because the vehicle is equippedwith a high-efficiency air-to-oilcooler, the transmission fluidtemperature may not reach the
required hot fluid level checkingtemperature under normal lightlyloaded driving vehicle conditions.
Checking the Fluid Level
Prepare the vehicle:
1. Park the vehicle on a levelplace. Keep the enginerunning.
2. With the parking brake applied,place the shift lever in P (Park).
3. With a foot on the brake pedal,move the shift lever througheach gear range, pausing forabout three seconds in eachrange. When M is reached,move the selector from M1through M3. Then, position theshift lever in P (Park).
4. Let the engine run at idle fortwo minutes or more.
Then, without shutting off theengine, use the steps that follow.

Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.
Engine Coolant
The cooling system in the vehicle isfilled with DEX-COOL®enginecoolant. This coolant is designed toremain in the vehicle for 5 years or240 000 km (150,000 mi), whicheveroccurs first.
The following explains the coolingsystem and how to check and addcoolant when it is low. If there is aproblem with engine overheating,seeEngine Overheating0230.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the
overheat warning. The engine
could catch fire and you or others
could be burned. Use a 50/
50 mixture of clean, drinkable
water and DEX-COOL coolant.
Use a 50/50 mixture of clean,drinkable water and DEX-COOLcoolant. If using this mixture,nothing else needs to be added.This mixture:
.Gives freezing protection downto✓37 °C (✓34 °F), outsidetemperature.
.Gives boiling protection up to129 °C (265 °F), enginetemperature.
.Protects against rust andcorrosion.
.Will not damage aluminum parts.
.Helps keep the proper enginetemperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
for the cooling system. See
Recommended Fluids and
Lubricants0305.
Never dispose of engine coolant byputting it in the trash, pouring it onthe ground, or into sewers, streams,
