The moin pipeline
routed under the cor f loor
consists of front ond reor pipes.
They ore em-
bedded in o chonnel moulded in the floor
boords ond rest on on insuloting (polysterene)
podding. From below, they ore protected
by
o guord,
the copscrews of which ore locked
in
position by spring woshers.
Use pipe
holders (yokes) to fosten the pipe-
line to the floor. In
the front
ond reor port
of
the cor, tighten
the pipes
over the insulotion
lrod ond insert
spring ond ploin
woshers under
the nuts.
Do not use insulotion pods
for bends
forming the tronsition from
the front
ond reor
lower flot ports.
Use spring woshers under
the
heods of copscrews.
Before instolling the pipes, prepore
ouxiliory
yokes (or use lengths of wires ottoched to the
provisionolly screwed-in copscrews of the pipe-
line guord) to liold the pipes
in the moulded
chonnel in
the floor before
the finol fostening
of their guord.
The woter line runs
under the cor together
with other lines, pull-rods,
etc. For their mutuol
ref otive orrongement see Chopter 12.7. Removol
To moke the underbody occessible for hond-
ling the pipes,

see the illustrotion in Chop-
ter 15.'13.
3. Remove one hose clip in the middle
of the
cor to disconnect
the pipes
(ottention -
the
remoining coolont will f low out), ond dis-
ossemble the line.
4. Disconnect the pipe
ends from the hoses,
ond detoch the pipes
from the floor or other
ports of the cor.
5. Pull out the reor pipes
possing
them core-

Reinstollotion Reverse the dismontling procedure
when re-
instolling the woter line. While connecting the
steering linkoge, poy
ottention to the condition
of boll pin
seoling cups (fit
new cups if the old
ore domoged). Fill in the recommended
coolont
ond bleed the cooling system.
11.5 COOLANT TEMPERATURE CONTROL
Throughf low Thermostot
This thermostot shuts off the inlet of the
coolont into the rodiotor
during the engine
heoting-up period. lt is mounted on the engine
- see Chopter 2.3, por.
30.
The thermostot operotes within the following
volues:
it begins to open ot 80+2"C
it is fully open ot 90+4oC
its lift ot full opening
11 mm
When closed, it
is permitted
to let poss
o nroximum
of 0.5 litres
of coolont per
minute,
ond it must not be closed by o bock pressure
of 0.16 MPo (1.6
kg/cm2).
When removing the thermostot by rototing
