PROCEDURE TO ADJUST THE SUBARU SUPER COOLANT CONCENTRATION

To adjust the concentration of SUBARU Super Coolant according to temperature, find the proper SUBARU Super Coolant concentration in the table, and add dilution water to the SUBARU Super Coolant (concentrated type) until it reaches the proper dilution.

TEMPERATURE CHART

Recommended engine coolant and dilution water

Refer to "RM" for recommended engine coolant and diluting water. Refer to COOLANT , RECOMMENDED MATERIALS, Recommended Materials.

1. Push the release lever to retract the push rod of the operating cylinder and check if the fluid level in the clutch reservoir tank rises or not.
2. If the fluid level rises, pedal free play is correct.
3. If the fluid level does not rise, or the push rod cannot be retracted, adjust the clutch pedal. Refer to «CLUTCH PEDAL»(ref-357242-S41420872202010031100000) .
4. Check the fluid level using the scale on the outside of the clutch reservoir tank (A). If the level is below "MIN" (B), inspect the clutch master cylinder, operating cylinder and hydraulic line for fluid leaks. If fluid leaks are found, repair or replace. If fluid leaks are not found, add clutch fluid to bring it up to "MAX" (C) of clutch reservoir tank.

Recommended clutch fluid: Refer to Recommended Materials information. Refer to FLUID , RECOMMENDED MATERIALS, Recommended Materials.

Note. Avoid mixing brake fluid of different brands to prevent fluid performance from degrading. Be careful not to allow dirt or dust to get into the reservoir tank.

1. Drain the gear oil by removing drain plug. CAUTION: If transmission gear oil is spilt over the exhaust pipe, wipe it off with a cloth to avoid emitting smoke or causing a fire. NOTE: Before starting work, cool off the transmission gear oil well. Drain the gear oil by removing drain plug using TORX® bit T70.
2. Replace the gasket with new part, and then tighten the drain plug to specified torque. Tightening torque: 44 N.m (4.5 kgf-m, 32.5 ft-lb) (Aluminum gasket silver) 70 N.m (7.1 kgf-m, 51.6 ft-lb) (Copper gasket brown) 70 N.m (7.1 kgf-m, 51.6 ft-lb) (Metal gasket black)
3. Fill the transmission gear oil through the oil level gauge hole up to the upper point of level gauge.

Recommended gear oil: Refer to Recommended Materials information. Refer to LUBRICANTS , RECOMMENDED MATERIALS, Recommended Materials.

Note. Each oil manufacturer has its base oil and additives. Thus, do not mix two or more brands.

Gear oil capacity: Refer to "Specifications" information. Refer to CAPACITY , Impreza.

WHEEL ALIGNMENT OF FRONT SUSPENSION

1. Check the alignment of front suspension to make sure the following items are within tolerance. Toe-in Camber Caster Steering angle Refer to «WHEEL ALIGNMENT»(ref-357247-S38606193512010031100000) .
2. When the caster angle does not conform to the reference value obviously, visually inspect the following components and replace deformed parts. Suspension components [Strut assembly, crossmember, front arm, etc.] Parts connecting suspension and body
3. When the toe-in and camber are out of tolerance value, adjust them so that they conform to standard value.
4. When the right-and-left turning angles of tire are out of standard, adjust to standard value.

WHEEL ALIGNMENT OF REAR SUSPENSION

1. Check the alignment of rear suspension to make sure the following items are within tolerance. Toe-in Camber Thrust angle Refer to «WHEEL ALIGNMENT»(ref-357248-S26494784682010031100000) .
2. When the camber angle does not conform to tolerance value, visually inspect the following components. If the deformation is observed, replace the damaged parts. Suspension components [Shock absorber, front lateral link, rear lateral link, upper arm, trailing link and sub frame] Parts connecting suspension and body
3. When the toe-in and thrust angle are out of tolerance value, adjust them so that they conform to tolerance value.
