The dipstick is located on the right-hand
side of the engine. The oil level should be
between the MAX and MIN marks on the
dipstick. To add oil, pour the oil into the
dipstick pipe. The clutch fluid is supplied
from the brake fluid reservoir.

Check the oil level as follows:
Set the hand brake and run the engine for at
least 15 seconds at idling speed with the
gear selector lever in the D position. Then at
least 15 seconds in the R position and 15
seconds in the P position, whereupon the
check is performed with the selector lever
still in the P position (engine running). Gra-
duations are provided for cold oil (104°F)
and hot oil (194°F). Note that at very low
temperatures the oil level can therefore lie
considerably under the level for cold oil
which has been graded for oil at a tempera-
ture of 104°. The difference between the
minimum and maximum levels is 1 pint
(0.5 litres).

To check the oil level, remove the filler hole
plug. Correct oil level is at or just below
(1/4
inch) the bottom ofthe filler hole. Use only
SAE EP80, API GL-4, or 5 gear oil for top-
ping up.
Cooling system
The cooling system is pressurized with a
crossflow radiator and expansion tank.
Until the engine has reached its operating
temperature, the radiator inlet is closed by
a thermostat and the coolant circulates
through the engine and the fresh air heater
until it reaches the temperature at which
the thermostat opens. The radiator fan is
electrically operated and is regulated by a
