2010 CHEVROLET IMPALA oil temperature

What to Use
{
WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s 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-COOL
®
coolant. If using this mixture, nothing else
needs to be added. This mixture:
•
Gives freezing protection down to−34°F (−37°C),
outside temperature.
•
Gives boiling protection up to 265°F (129°C),
engine temperature.
•
Protects against rust and corrosion.
•
Will not damage aluminum parts.
•
Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater core,
and other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 7-10for more information.

Overheated Engine Protection
Operating ModeThis 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 firing groups of
cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The coolant 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 6-15.
Power Steering Fluid
The power steering fluid
reservoir is located toward
the rear of the engine
compartment on the
passenger’s side of the
vehicle. SeeEngine
Compartment Overview on
page 6-14for reservoir
location.
When to Check Power Steering FluidIt is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
