Reinstall the expansion tank filler cap. After a test drive recheck the coolant level. See "filling capacities" for amount
required.

Manual Transmission oil
Both transmission and final drive are
combined in one housing. The lubricant used
is hypoid oil.
The manual transmission oil should be
checked and changed by your Porsche dealer
and at the intervals specified in your
Maintenance Schedule.
77

Automatic Transmission Fluid The torque converter and the transmission are lubricated with Automatic Transmission Fluid
(ATF). The final drive requires hypoid oil SAE
90 only.
Do not tow the car or run the engine
without ATF in the transmission.
Checking the ATF level
The ATF has to be checked at frequent
intervals, for instance, when the engine oil is
being checked or at least at the specified
intervals (see Maintenance schedule). A
correct ATF level is very important for the
proper functioning of the transmission. The
reading should be done when the ATF is warm, with the engine idling, the selector lever in Neutral and the parking brake applied.
The level of the ATF fluid can be checked
visually through the transparent reservoir. This reservoir is located at the rear end of the
transmission housing. You have enough ATF
if the fluid level is between the Min. and Max.
marks. It should never be above or below
these marks.
The difference between the two marks is 1
U.S. pint or 0.4 liter.
If level is too high or too low do not just add or
drain ATF. Have your dealer check and
correct the cause as soon as possible.
For correct ATF specifications, see "Filling
Capacities".
Changing the ATF

The ATF and the hypoidoil in the final drive
has to be changed at specified intervals (see
Maintenance schedule).

Jacking at any other place may damage the vehicle o r may
result in personal injuries.
Changing a Tire
WARNING - Failure to follow these
instructions may result in serious personal injuries to you or to bystanders.
If you have a flat tire, move a safe distance off the road. Turn the emergency flasher on and use other warning devices
to alert other motorists.
Passengers must not remain in the vehicle when it is jacked up. Before you change a tire, be sure the ground is level and firm. If necessary, use a board under the jack to ensure that the jack does not sink into the ground. Set the parking brake and block the wheels opposite the flat tire on the other
side of the vehicle.
The jack is only to be used for changing
a tire. Do not use it as a support to work
under the car.
Never jack the car up by the body or the bumpers.
Sequence of operations:
1.
Loosen all wheel nuts. Do not yet remove
nuts.
2.
Securely place the jack in the jack support
at the indicated point. Place the jack at an
angle so that the jack base rests firmly on
the ground. If the ground is not firm under
the jack, use a board.
Do not raise the vehicle until you are sure
the jack is securely engaged.
3.
Raise the car by turning the handle
clockwise. Only raise the car as much as is
needed to change a wheel.
4.
Fully unscrew wheel nuts and remove wheel.

5. After you have mounted the spare wheel, insert the wheel nuts and hand tighten them crosswise. Snug wheel nuts with socket wrench and breaker bar.
6. To lower the car, turn the handle
counterclockwise till tire touches ground.
7.
Then go crosswise from one nut to another
tightening them firmly with the socket
wrench and breaker bar.
8. Fully lower the vehicle and remove jack.
9. Correct the air pressure of the tire you have just put on. Have flat tire repaired at next service stop.
Correct tightness of the wheel nuts is
important. The torque of 94 ft Ib (130 Nm) can
be obtained with a socket wrenc
h and breaker bar by any person of average strength. If in
doubt about the correct tightness of the wheel
nuts, have it checked with a torque wrench by
your dealer or a service station.

Lifting Vehicle

The jack ports are located below the middle of the door underneath the left and right rocker
panels, hidden from view.
Lifting with car jack
The car jack must never be used as a
support to work underneath the vehicle. If
the jack is accidentally dislodged, you
could be seriously injured. When working
under the vehicle always use safety stands specifically designed for this purpose.
WARNING
Jacking at any other place may damage the vehicle or may result in personal injuries.
The vehicle should never be lifted or jacked up from underneath the engine oil pan, the transmission housing, or the front or rear axle. This could lead to serious
damage.
Lifting with workshop hoist
Make sure there is sufficient clearance
between pads and vehicle before driving
vehicle onto hoist, especially if the vehicle
has a large front panel or spoiler. The vehicle must be lifted only at the lift points illustrated.
The front lift points are located on the inboard
side members of the underbody.
The rear lift points are located on the side
reinforcement brackets of the underbody.
Take care to avoid damaging critical
components which are close to the lift
points.
WARNING
When removing components such as
engine block, transmission housing, fuel
tank, wheels, front or rear axle, anchor
vehicle to hoist or add corresponding
weights to maintain the center of gravity.
Otherwise the vehicle might tilt or slip off
the hoist, causing serious damage or
personal injury.
Lifting with floor jack

The same lift points as illustrated for the hoist
also apply when using a floor jack. To avoid
damage to the underbody or chassis frame, it
is necessary to insert a rubber pad between
the floor jack and the lift points.

must be charged at least every 6 weeks. A
discharged battery allows rapid formation of
sulfates, leading to premature deterioration of
the plates.
WARNING
Charge battery in a well ventilated area.
Keep away from open flame or electrical
spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
Electrolyte fluid that may spill during charging should be washed off with a solution of warm water and baking soda to neutralize the acid. If you get electrolyte in your eyes or on your
skin, immediately rinse with cold water for
several minutes and call a doctor.
Never charge a frozen battery. It may
explode because of gas trapped in the ice.
Allow a frozen battery to thaw out first. Never use a fast charger as a booster to start the engine. This may seriously damage the
vehicle's electrical system and the charger.
Fast charging a battery is dangerous and
should only be attempted by a competent
mechanic with the proper equipment.
