Safety With the Cooling System
Keep these 8 safety precautions in mind when working with the cooling system.
1. When working on the cooling system, remember
that at operating temperature, the coolant is
extremely hot, approximately 220 plus degrees
Fahrenheit. Touching the coolant or spilling the
coolant on the body can cause serious injury.
2. When replacing the water pump or thermostat, any
coolant spilled on the floor can be very slippery.
Immediately wipe up any coolant that spills to
reduce or eliminate the chance of injury.
3. Always wear proper clothing and eye protection
when using coolant additives to remove silicate
and calcium deposits. They may be very corrosive.
4. When working on the fan, water pump, or belts,
make sure the engine ignition system is off, or the
battery is disconnected, or both.

5. When working on the cooling system and running
the engine, always keep fingers, tools, and clothing
away from the moving fan.
6. Never remove the pressure cap when the engine
is hot. Removing the pressure cap releases the
pressure on the cooling system. This reduces the
boiling point of the coolant. The coolant will then
boil violently and burn or injure a person's hands
7. Keep antifreeze away from children and animals.
Antifreeze has a sweet taste, and, if consumed
can lead to death in as little as 24 hours. If
antifreeze is ingested, immediately contact a
doctor, hospital, or poison control center.
8. Always dispose of used antifreeze in an approved
container. Never pour used antifreeze down the
water drain. To dispose of antifreeze, take it to a
recycling center (if one is available) or take it to
local service garage for disposal. Always check
the local and state EPA requirements before
