1987 PORSCHE 944 Tire

Sealed Beam Headlights
Replacing light units
1.
Turn on the ignition and depress light switch to the second stop to raise the concealed
headlights. Then turn off the ignition.
2.
Remove Phillips screw from headlight trim
(arrow), take off the plastic cover.
3.
Remove only the three recessed screws
(arrows) which secure the lamp unit
retaining ring, remove retaining ring, and
take out sealed beam unit.
4.
Disconnect plug from rear of unit.
5. Attach plug to rear of new unit.
6. Insert sealed beam unit and retaining ring,
tighten hold-down screws.
7.
Check headlight adjustment.
8. Install headlight trim and tighten retaining
screw.

Adjusting Headlights
Headlight adjustment should be done with a
headlight aiming device under the following
conditions:
At curb weight of car (i. e. car ready for use
and with full fuel tank).
Driver's seat should be occupied by a person
or a weight of approx. 165 Ibs (75 kg).
Tire pressure must be correct.
Roll car forward a few feet so that the
suspension seeks its normal position.

Engine Oils
Use only engine oils which meet the
specifications designated by PORSCHE. Your Porsche dealer will be glad to advise you on
the correct type of oil for your engine.
All current engine oils are compatible with each other, i. e. when making an oil change it
is not necessary to flush the engine if you
wish to use a different brand or grade of oil. Since, however, each brand of oil has a
special composition, you should, if possible,
use the same oil brand if it becomes
necessary to top up between oil changes.
PORSCHE engines have long intervals
between oil changes. You can make best use
of these long oil change intervals by using
multigrade oils since these are largely
independent of seasonal fluctuations in
temperature.
If your vehicle is used frequently in stop-and-
go traffic in winter, the engine will not always
be properly warmed up. Condensation from
products of combustion may accumulate in
the oil. In this case, it is advisable to change
the oil in spring so that your engine once
again has a 100% efficient engine oil.
Engine oil performance class

Engine oil is not only a lubricant, but also
serves to keep the engine clean, to neutralize
the dirt which penetrates into the engine
through combustion and to protect the engine
against corrosion. To perform these functions, the oil is provided with additives which have
been specially developed for these functions.
So-called mineral oils are produced directly
from crude oil. The oils can be further refined
(hydrocrack oils) or totally converted through a number of chemical processes (synthetic oils). These oils are structurally more efficient and
require fewer additives than simple mineral
oils.
The efficiency of an oil is expressed, for
example, by the API classifications which are
divided into categories "S" and "C". The
degrees of quality are expressed by final
letters in alphabetical order: The requirements for PORSCHE engines are API class SE/CC
to SF/CD.
Viscosity
Like all liquids, engine oil is viscous when
cold, and thin-bodied when warm.

The viscosity of an oil is expressed by its SAE class. For cold viscosity (measured at
temperatures below 0°C) the SAE class is
given as a number and the letter "W" (as in
winter); for hot viscosity (measured at 100°C) the SAE class is given only as a number. The viscosity of an oil is, therefore, always the same if it has the same number of an SAE
class.
E. g.: A 10 W -30 oil and a 10 W-40 oil have
the same viscosity when cold (below 0°C);
when hot (at 100°C) the oil with the number 30 is thinner than the oil with the number 40.
Single-grade/multigrade oils
Oils with two viscosities are called multi-g
rade oils; oils with only one viscosity are termed
single-grade oils.
Single-grade oils can only be used for the
narrow temperature range identified by their
SAE number; multigrade oils cover a wider
temperature range (see chart).
Fuel efficient oils
Fuel efficient oils reduce internal friction in the
engine. PORSCHE approves only fuel
efficient oils which are structurally so stable
that they can be used in PORSCHE engines
both as summer and winter oils (see chart of
areas of application for oils of different
viscosity). These conditions are currently
fulfilled by synthetic or hydrocrack fuel
efficient oils.

*** Applies only if the basic rack of the original Porsche Roof Transport System is used. If old type Porsche ski and luggage racks are used the
permissible roof weight is 35 kg (77 Ibs.).
The vehicle capacity weight (max. load), the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Wei ght Ratings (GAWR) for front and
