SERVICING
20 Replacing the air cleaner paper filter
The air cleaner consists of a plastic cover
with replaceable paper filter insert. The
i nsert should be replaced after every
40,000 km (25,000 miles). Replacement
should be carried out more frequently if
the driving conditions are often dusty. No
other kind of servicing is required outside
these intervals.
To replace release the tensioning clips
securing the air cleaner cover. The cover
can then be opened so much that the in-
sert is accessible for replacement.

20 a Replacing foam plastic filter for
evaporative control system
On vehicles fitted with an evaporative
control system, the foam plastic filter in the
holder on the cowl to the right in the
engine compartment should be replaced
every 40,000 km (25,000 miles).
21 Valves
The valve clearances should be checked
after every 10,000 km (6000 miles).
This check should be carried out by a
workshop.
22 Compression test
To get some idea of the condition of the
engine, a compression test should be
made after every 10,000 km (6000 miles).
This test should preferably be carried out
by a workshop.
23 Fan belt
The fan belt tension should be checked
every 10,000 km (6000 miles). Due to wear
or dirt, this belt can start slipping with
poor cooling and poor alternator output
as the result.
The check can suitably be carried out by
a Volvo workshop.
To test the tension provisionally press in
the fan belt at a point midway between the
alternator and the fan. It should be pos-
sible to press down the belt about 10 mm
(

with normal pressure (11.5-14 kp =
85-100 Ib.ft.)
24 Check the coolant level
The cooling system must be well filled
with coolant and not leak if it is to operate
at maximum efficiency. Check the coolant
l evel when filling up with fuel. The level
should be between the "Max" and "Min"
marks on the expansion tank.
The check should be carried out with
particular thoroughness when the engine
i s new or the cooling system has been
empty.
Do not remove the filler cap other than
for topping-up with coolant. Frequent
removal interferes with the coolant circu-
l ation between the engine and the expan-
sion tank during engine warming up and
cooling.
