1. DRAINING OF ENGINE COOLANT
S176060A2001
1)   Lift-up the vehicle.
2)   Remove under cover.
3)   Remove drain cock to drain engine coolant into container.
NOTE:
Remove radiator cap so that engine coolant will
drain faster.

3)  Warm-up engine completely for more than five minutes at 2,000 to 3,000 rpm.
4)   If engine coolant level drops in radiator, add engine coolant to filler neck position.
5)   If engine coolant level drops from upper level of reservoir tank, add engine coolant to upper level.
6)  Attach radiator cap and reservoir tank cap prop­erly.

2. FILLING OF ENGINE COOLANT
S176060A2002
1) Fill engine coolant into radiator up to filler neck position.
Coolant capacity (fill up to "FULL" level): Non-turbo AT model
Approx. 6.4 £ (6.8 US qt, 5.6 Imp qt) Non-turbo MT model
Approx. 6.3 £ (6.7 US qt, 5.5 Imp qt) Turbo model
Approx. 7.2 £ (7.6 US qt, 6.3 Imp qt)
CAUTION:
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.
TEMPERATURE
S176060A1001
The concentration and safe operating temperature of the SUBARU coolant is shown in the diagram. Measuring the temperature and specific gravity of the coolant will provide this information.

ENGINE COOLANT
Cooling
[Example]
If the coolant temperature is 25°C (77°F) and its specific gravity is 1.054, the concentration is 35% (point A), the safe operating temperature is -14°C (7°F) (point B), and the freezing temperature is -20°C (-4°F) (point C).
[Example]
Assume that the coolant concentration must be increased from 25% to 40%. Find point A, where the 25% line of coolant concentration intersects with the 40% curve of the necessary coolant concentration, and read the scale on the vertical axis of the graph at height A. The quantity of cool­ant to be drained is 2.1 liters (2.2 US qt, 1.8 Imp qt). Drain 2.1 liters (2.2 US qt, 1.8 Imp qt) of cool­ant from the cooling system and add 2.1 liters (2.2 US qt, 1.8 Imp qt) of the undiluted solution of SUBARU coolant.
If a coolant concentration of 50% is needed, drain all the coolant and refill with the undiluted solution only.

2. PROCEDURE TO ADJUST THE CONCENTRATION OF THE COOLANT
S176060A1002
To adjust the concentration of the coolant accord­ing to temperature, find the proper fluid concentra­tion in the above diagram and replace the neces­sary amount of coolant with an undiluted solution of SUBARU genuine coolant (concentration 50%). The amount of coolant that should be replaced can be determined using the diagram.
