Drive belts
1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulley
The alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires that belt tension be correct.
To check belt tension, place a straight-
edge (ruler) across two adjacent pulleys
and apply a force of 22 lbs (98 N, 10 kg)
midway between the pulleys by using a
spring scale. Belt deflection should be the
amount specified. If a belt is loose,
cracked, or worn, contact your SUBARU
dealer.
