WINDSHIELD WASHER FLUID
The reservoir capacity is 4.0 quarts
(3.8L); use windshield washer fluid
that meets the Ford specification
listed. Refer toLubricant
specificationsin this chapter.
Inspect the fluid level in the washer
reservoir when insufficient fluid is
sprayed.
State or local regulations on volatile
organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
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 or washer system.
Do not put engine coolant in the washer fluid reservoir. Engine
coolant can severely reduce visibility if sprayed on the
windshield.
