CAUTION:
If your vehicle has air conditioning, the auxiliary electric fan
under the hood can start up even when the engine is not running
and can injure you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant surge tank is boiling, don't do anything else
until it cools down.
The coolant level
should be
at

the COLD mark. If it
isn't, you may have a
leak in the radiator
hoses, heater hoses,

or somewhere else in
the cooling system.
