GMC 2005 Savana - Manual (Page 264)

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.
Notice: If your engine catches fire because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not
be covered by your warranty.
If No Steam Is Coming From Your
Engine
If you get an engine overheat warning but see or hear
no steam, the problem may not be too serious.
Sometimes the engine can get a little too hot when you:
• Climb a long hill on a hot day.
• Stop after high-speed driving.
• Idle for long periods in traffic.
• Tow a trailer. See “Driving on Grades” under
Towing a Trailer on page 4-36.
