On automatic transmission models, the radiator contains a heat exchanger to cool the transmission fluid.
Use caution: do not attempt to remove the expansion tank cap when the engine is hot, as you run the risk of getting burned. If the cover must be removed under these conditions (although it is NOT recommended), you need to reduce the pressure in the system. Cover the lid with a thick layer of cloth so as not to burn yourself, slowly unscrew the neck cap until a hissing sound is heard. Once the hissing stops, slowly unscrew the filler cap.
Do not allow antifreeze to get on the skin or painted surfaces of the car. Wash off any antifreeze stains immediately with plenty of water. Never leave antifreeze in an open container. Children and pets are attracted to the pleasant smell of antifreeze, but inhaling antifreeze can be fatal.
If the engine is hot, the cooling fan may turn on even if the engine is not running, so be careful to keep your hair, clothes, etc. out of the way while working in the engine compartment. were away from the fan.
