Engine Coolant - Ford Mustang Owner's Manual

as methanol should be used in freezing weather
(temperatures below 32˚F [0˚C]). State or local
regulations on Volatile Organic Compounds
(VOCs) may restrict use of the most common
antifreeze, methanol. Washer fluids containing
non-methanol antifreeze agents should be used
only if they provide cold weather protection
without damaging the vehicle's paint finish,
wiper blades, and windshield washer system.

Checking the Engine Coolant
NOTE: Be sure to read and understand
Precautions When Servicing Your
Vehicle at the beginning of this chapter.
The cooling fan is automatic and may
come on at any time. Always disconnect
the negative terminal of the battery before
working near the fan.
Your vehicle's coolant protects your engine from
overheating in the summer and from freezing in
the winter. Check the level of the coolant at least
once a month. Simply look at the engine coolant
reservoir located in the engine compartment. To
locate the reservoir, see the diagram of your
vehicle's engine under Engine Type, in this
chapter.
The coolant additives also protect the entire
cooling system from internal passageway
corrosion and these additives lubricate the water
pump. The coolant should be serviced as noted
in the Maintenance Schedule booklet.
