Cooling System: Service and Repair

Engine Coolant

Replacement

Draining Of Engine Coolant
1. Lift-up the vehicle.
2. Remove the under cover.
3. Remove the drain cock to drain engine coolant into container.

NOTE:
^ Remove the coolant filler tank cap so that engine coolant will drain faster.
^ If engine coolant adheres to the exhaust pipe, wipe it off completely.





4. Install the drain cock.

Filling Of Engine Coolant
1. Pour cooling system conditioner through the filter neck.
^ Cooling system protective agent: COOLING SYSTEM CONDITIONER (Part No. SOA635071)
2. Fill engine coolant into the coolant filler tank up to filler neck position.
^ Coolant capacity (fill up to "FULL" level):
^ AT model Approximately 7.6 L (8.0 US qt, 6.7 Imp qt)
^ MT model Approximately 7.7 L (8.1 US qt, 6.8 Imp qt)

CAUTION: Do not mix up the coolant filler tank side cap with radiator side cap.

NOTE:
^ Do not remove the radiator side cap when filling engine coolant.
^ The SUBARU Genuine Coolant containing antifreeze and anti-rust agents is especially made for SUBARU engine, which has an aluminum crankcase. Always use SUBARU Genuine Coolant, since other coolant may cause corrosion.

3. Fill engine coolant into the reservoir tank up to "FULL" level.





4. Close the coolant filler tank cap, start the engine and race 5 to 6 times at less than 3,000 rpm, then stop the engine. (Complete this operation within 40 seconds.)
5. Wait for one minute after the engine stops, open the coolant filler tank cap. If the engine coolant level drops, add engine coolant to the filler neck position of radiator.
6. Perform the procedures 4) and 5) again.
7. Attach the coolant filler tank cap and reservoir tank cap properly.
8. Start the engine and operate the heater at maximum hot position and the blower speed setting to "LO".
9. Run the engine at 2,000 rpm or less until radiator fan starts and stops.

NOTE:
^ Be careful with the engine coolant temperature gauge to prevent overheating.
^ If the radiator hose becomes to harden by the pressure of engine coolant, air bleeding operation seems to be almost completed.

10. Stop the engine and wait until engine coolant temperature lowers to 30°C (86°F) or less.
11. Open the coolant filler tank cap. If the engine coolant level drops, add engine coolant into the coolant filler tank up to the filler neck position and the reservoir tank to "FULL" level.
12. Attach the coolant filler tank cap and reservoir tank cap properly.
13. Operate the heater at maximum hot position and the blower speed setting to "LO" and start the engine. Race at less than 3,000 rpm. If the flowing sound is heard from heater core, repeat the procedures from step 9).
14. Install the collector cover.
