Wipers - Saab 9001994 Owner's Manual

78 Car care and technical information
NOTE
In conditions other than normal driving,
Turbo models may require a different
spark plug than is fitted as standard
e9u!pment. Extensive idling, stop-and-go
driving and operation in cold climates
over repeated short trips without sufficient
engine warmup may cause Turbos to re-
~uire
the spark plug listed for City Driving
In
the Specification section of this book.
Discuss this with your dealer.
If the spark plugs are removed, take care
that no dirt enters the cylinders. Use only
the recommended spark plug heat range.
Gap the spark plug to specification.
Resistor-type plugs should not be used.
Ignition lead runs
S3797
Resistive wire leads are used for radio in-
terference suppression.
To remove the plugs you must first remove
~he
two screws holding the spark plug cover
In
place and remove the cover. On all en-
gines remove the plug wires by gripping the
protective boot with special boot removal
pliers to prevent damage to the wire. Never
pull directly on the wire. Install spark plugs
carefully to avoid damage to the threads in
the
~Iuminum
cyli.nder head. The firing or-
der
IS
1-3-4-2 (cylinder number 1 is closest
to the firewall).
Wipers
Inspect and clean the rubber blades of the
win~shield
at regular intervals. Methyl alco-
hol
IS
recommended for cleaning. If the
blades show signs of wear, they should be
replaced. For best windshield wiper perfor-
mance the glass must be free of wax and
oily road grime.
Changing the windshield wiper
blades
Lift the wiper arm away from the windshield.
Depress the plastic clip (1) and slide the
complete wiper blade assembly out of the
loop at the end of the wiper arm (2).
Free the blade rubber from the retainer (see
illustration) by pressing together the two
shiny metal pieces and twisting the rubber
to disengage the retainer from the recess
in the blade. The rubber can now be with-
drawn through the other retainers. To fit the
rubber, slide it through the four retainers
and then tighten it so that the retainer at one
end engages the recess in the blade rub-
ber.
Complete replacement blade assemblies
are also available from your Saab dealer.
