Buick 2005 manual Radiator Pressure Cap, Engine Overheating, If Steam Is Coming From Your Engine

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 for the 3400 V6 engine and the 3.6L V6 engine are located in different areas of the engine compartment. See Engine Compartment Overview on page 5-12for more information on location.

Engine Overheating

You will find an engine coolant temperature gage on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 3-46. You also have an engine coolant temperature warning message on

your instrument panel. See Engine Coolant Temperature Warning Message on page 3-52. If your vehicle is equipped with the 3.6L V6 engine, you will have a reduced engine power message as well. See Reduced Engine Power Message on page 3-53.

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 5-30 for information on driving to a safe place in an emergency.
