Brake fluid

Clutch control fluid
The fluid level in the brake and
clutch
control hydraulic
systems
should be checked after every 5 000
km (3 000 miles). The fluid should
be up to the level marks in the
containers.
Use brake fluid for both
systems.

Oil filler cap
The oil filler cap is fitted with a
filter. If this filter becomes blocked
there
will be excessive pressure in
the crankcase and this can lead to
oil leakage. This filter must there-
fore be cleaned after about every
40 000 km (25 000 miles).
12
Crankcase ventilation
Some models are provided with po-
sitive
crankcase ventilation
which
prevents crankcase gases from being
released into the atmosphere. The
valve (4) should be replaced at In-
tervals of 40 000 km (25 000 miles).
The oil trap (6), the hoses (3 and 5),
the
nipple (1) and the filter (2)
should be removed at the same time
and thoroughly cleaned. If the rub-
ber hoses should be in a poor con-
dition, then replace them.
13
Oil filter
The oil filter traps any impurities
i
n the oil so that the filter becomes
blocked after a time. For this reason
it
must be replaced regularly, for
example after every 10 000 km
(6 000 miles), and preferably by a
Volvo
workshop. If the filter is
replaced
without
the
oil
being
changed, 0.5 litre (A Imp. pints =
1
1
/4
US pints) of oil should be ad-
ded.
38
Brake fluid
The brake fluid used in the hydrau-
lic
brake system
must
meet the
standards laid down in SAE 70 R 3.
From the point of view of traffic
safety it is extremely important to
ensure that poor quality brake fluid
is
not used in the hydraulic brake
system.
A top-quality brake fluid
must satisfy strict conditions con-
cerning resistance to cold and heat
and must have no detrimental effect
on the rubber components in the
brake system.
