the air cleaner intake and this is designed to ensure that
the intake air maintains a constant temperature of around
86°F (30°C). There are two air intakes, one for cold air
and one for heated air. The cold air intake points for-
ward while the preheated air is supplied by a hose con-
nected to a box mounted on the exhaust pipe.

Checking
To carry out the following check, disconnect the cold air
intake from the valve assembly and observe the position
of the valve.
1. With the engine switched off and cold, and an am-
bient temperature of less than 68°F (25°C), the valve
should shut off the cold air intake.
2. When the engine is running and the ambient air tem-
perature is less than 86°F (30°C), the valve should be
in the intermediate position, allowing cold and warm
air to mix to a suitable temperature. At very low tem-
peratures, the cold air intake will be shut off complete-
Iv. When the ambient temperature exceeds 86°F (30°C)
the warm air supply will be completely shut off.
Checking dismantled valve assembly
Sweden-version, model 1976 and 1977
1. Remove the air preheater from the air cleaner.
2. Place the flap valve under running water with a tem-
perature of 68°F (25°C). The flap valve will now
shut the cold air intake.
3. Raise the water temperature to 95°F (35°C). The
flap valve will now shut the warm air intake.
