oil cooler lines to lower radiator tank. It is essential
that no dirt enters the oil lines. When tightening oil
lines hold connectors on lower radiator tank with
pliers to avoid leakages. Ensure that no dirt enters oil
cooler. Torque to 11-15 Ibs. ft.
7. Install fan shroud.
9. Install lower radiator hose and add collected coo-
lant.
All Opel 1900's and Manta's are provided with a
radiator initial fill of an anti-freeze solution contain-
ing corrosion inhibitor. The anti-freeze has either a
glycol or glycerin base and protects the engine
against freezing, down to minus 22 degrees F. (minus
30 degrees C.). Before the start of the cold season,
coolant must be checked with a hydrometer and if
necessary, brought to the necessary specific gravity
by adding anti-freeze. Anti-freeze added, must have
a glycol or glycerin base. As the specific gravities of
all anti-freeze solutions having a glycol or glycerin
base are practically the same, the hydrometer can be
used for all these types. Because of the tolerances of
the hydrometer, or slight differences in specific
gravity, variations of plus or minus 5 degrees can be
expected. Coolant must be checked at a temperature
of plus 68 degrees F. (plus 20 degrees C.).
IO. Install negative battery cable and air cleaner.
