2019 Subaru Forester Owners Manual - Cooling system

Cooling system

Your vehicle employs an electric cooling fan which is thermostatically controlled to operate when the engine coolant reaches a specific temperature.

If the radiator cooling fan does not operate even when the coolant temperature high warning light blinks or illuminates in RED, the cooling fan circuit may be defective. Refer to “Coolant temperature low indica- tor light/Coolant temperature high warning light”  P168.

Check the fuse and replace it if necessary. Refer to “Fuses”  P476 and “Fuse panel located in the engine compartment”

 P499.

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.

“FULL” level mark

“LOW” level mark

Check the coolant level at each fuel stop.

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

If the level is close to or lower than the “LOW” level mark, add coolant up to the “FULL” level mark. If the reserve tank is empty, remove the radiator cap and refill coolant up to just below the filler neck as shown in the following illustration.

Fill up to this level.

After refilling the reserve tank and the radiator, reinstall the cap and check that the rubber gaskets inside the radiator cap are in the proper position.

It may be difficult to change the coolant. Have the coolant changed by your SUBARU dealer if necessary.

The coolant should be changed according to the maintenance schedule in the “War- ranty and Maintenance Booklet”.

The air cleaner element functions as a filter screen. When the element is perforated or removed, engine wear will be excessive and engine life shortened.

It is not necessary to clean or wash the air cleaner element.
