WARNING: This page is about a different car, the 2002 Subaru Forester and 2001 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When checking operation, securely apply the hand brake.

When testing with gauges, connect gauges as shown. See Fig 1
. After bleeding air from pressure gauges, proceed to each check.
