Engine Coolant - Subaru WRX 2021 Owner's Manual

Temperature gauge
1) Normal operating range
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to "Temperature gauge"
F3-11.
Check the fuse and replace it if necessary.
Refer to "Fuses" F11-42 and "Fuses and
circuits" F12-10.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
If the frequent addition of coolant is
necessary between vehicle service visits,
it is recommended that you have your
vehicle inspected by an authorized
SUBARU dealer to check for leaks, da-
mage, or looseness.

1. Check the coolant level on the outside
of the reservoir while the engine is cool.
