Drive belts
1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulley
The alternator, power steering pump, and air condi-
tioner compressor depend on drive belts. Satisfactory
performance requires that belt tension be correct.
To check belt tension, place a straightedge (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.
