11-14Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33F ( –36 C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,
even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehic le emp loys an elec tric c ooling fan whic h is thermostatic ally
