Maintenance and service/Cooling system
Check the fuse and replace it if necessary.
Refer to Fuses 11-42 and Fuses and
circuits 12-10.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness.
