This could damage your cooling
system. Do not add engine coolant to
the washer fluid reservoir. This could
damage your wiper/washer system.
Use specially formulated windshield washer
fluid rather than plain water, because specially
formulated washer fluids contain additives that
dissolve road grime. For safety reasons, washer
fluids containing an appropriate antifreeze such

regulations on Volatile Organic Compounds
(VOC's) 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.
Washer solution contains methanol
which is poisonous. Observe all
warnings indicated on label of
washer solution.
