Engine Coolant; Checking The Coolant Level - Subaru 1998 Forester Owner's Manual

Your vehicle employs an electric cooling fan which is thermostatically
controlled to operate when the engine coolant reaches a specific tem-
perature.
If the radiator cooling fan does not operate even when the engine cool-
ant temperature gauge exceeds the normal operating range, the circuit
of the cooling fan may be defective. Check the fuse and replace it if nec-
essary. If the fuse is not blown, have the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is necessary, 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.

J Checking the coolant level
WARNING
D Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolant
is under pressure, you may suffer serious burns by a spray of
boiling hot coolant when the cap is removed.
D Never let engine coolant contact your eyes because engine
coolant can be harmful to your eyes. If engine coolant gets in
your eyes, immediately flush them thoroughly with clean water.
For safety, when performing this work, wearing eye protection is
advisable.
Check the coolant level at each fuel stop.
