Coolant

ENGINE COOLANT
50/50 mixture of clean, drinkable water and use only DEX-COOL Coolant.

ENGINE COOLANT
The cooling system in the vehicle is filled with DEX-COOL engine coolant. This coolant is designed to remain in the vehicle for 5 years or 240,000 km (150,000 mi), whichever occurs first, if you add only DEX-COOL extended life coolant. The following explains the cooling system and how to add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating. A 50/50 mixture of clean, drinkable water and DEX-COOL coolant will:

- Give freezing protection down to -37°C (-34°F).

- Give boiling protection up to 129°C (265°F)).

- Protect against rust and corrosion.

- Help keep the proper engine temperature.

- Let the warning lights and gauges work as they should.

Notice: Using coolant other than DEX-COOL may cause premature engine, heater core, radiator, and fuel operated heater (van models only) corrosion. In addition, the engine coolant may require changing sooner, at 50 000 km (30,000 mi) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL (silicate-free) coolant in the vehicle.

WHAT TO USE
Use a 50/50 mixture of clean, drinkable water and DEX-COOL coolant which will not damage aluminum parts. If using this mixture, nothing else needs to be added.

Warning: Adding only plain water or some other liquid to the cooling system can be dangerous. Plain water and other liquids, 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.

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.

If coolant has to be added more than four times a year, check the vehicle cooling system.

Notice: If you use extra inhibitors and/or additives in your vehicle's cooling system, you could damage your vehicle. Use only the proper mixture of the engine coolant listed in this manual for the cooling system.

Never dispose of engine coolant by putting it in the trash, pouring it on the ground, or into sewers, streams, or bodies of water. Have the coolant changed by an authorized service center, familiar with legal requirements regarding used coolant disposal. This will help protect the environment and your health.
