For 1990-2009 cars

There is a High Engine Coolant Temperature/Automatic Transaxle Fluid Temperature Warning Light, and a Low Coolant Level Warning Light on your Saturn instrument panel.

If the light comes on and stays on, you could have one or both of the following two conditions:

• | Overheated engine coolant

• | Overheated automatic transaxle fluid

### 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 the engine catches fire because of being driven with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty.

### If No Steam Is Coming From Your Engine

If you get an engine overheat warning with no warning messages, 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.

If you get the overheat warning with no sign of steam, try this for a minute or so:

1. If you have an air conditioner and it's on, turn it off.
2. Turn on your heater to full hot at the highest fan speed and open the window as necessary.
3. Try to minimize engine load. If you're in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving.

If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn't come back on, you can drive normally.

If the warning continues and you have not stopped, pull over, stop, and park your vehicle right away.

If there's still no sign of steam, you can idle the engine for two or three minutes while you're parked. If you still have the warning, TURN OFF THE ENGINE AND GET EVERYONE OUT OF THE VEHICLE until it cools down.

You may decide not to lift the hood, but to get service help right away. When you decide it's safe to lift the hood, here's what you'll see:

• | Coolant surge tank with pressure cap

• | Electrical engine coolant fan

If the coolant inside the coolant surge tank is boiling, don't do anything else until it cools down. The coolant surge tank should always be cool to the touch before the surge tank cap is removed.

The vehicle should be parked on a level surface. The coolant level should be in the "MIN./MAX. COLD" range. If it isn't, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.

If there seem to be no leak, with the engine running, check to see if the electric engine cooling fan is running. If the engine is overheating, the fan should be running. If it isn't, your vehicle needs service. Turn off the engine.
