Buick 2005 LaCrosse - Manual (Page 300)

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 arrows on the cap line
up with the overflow tube on the radiator filler neck.
The radiator pressure cap is located in the front of the
engine compartment on the passenger’s side of the
vehicle. See Engine Compartment Overview on
page 5-12 for more information on location.
Engine Overheating
There is a coolant temperature gage and a warning light
on the instrument panel cluster that indicate an
overheated engine condition. See Engine Coolant
Temperature Gage on page 3-38 and Engine Coolant
Temperature Warning Light on page 3-38 for more
information.
In addition, if your vehicle is equipped with a Driver
Information Center (DIC), you will find an ENGINE
COOLANT HOT and a REDUCED POWER STOP
WHEN SAFE message displayed on the DIC. See DIC
Warnings and Messages on page 3-53 for more
information.
If Steam Is Coming From Your Engine
{ CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood. Stay
away from the engine if you see or hear steam
coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
See Overheated Engine Protection Operating
Mode on page 5-26 for information on driving
to a safe place in an emergency.
