1995 SUBARU LEGACY low oil pressure

NOTE:
After installing condenser, ensure that guide on lower side
of condenser is inserted into hole in radiator panel. Tighten
attaching bolts.
9) Charge refrigerant.
B: INSPECTION
1) Make sure the condenser fins are free from dust and
insects. If the fins are clogged, clean by blowing air or
water through them.
NOTE:
To prevent dust and water from getting into the condenser,
this work must be done when the condenser is installed in
an actual vehicle.
2) Check the condenser to see if it shows any sign of oil.
Should oil ooze or gas leak from the condenser replace it
with a new one.
