11.8 HEATER
CONNECTING LINE
The line is o
combinotion of steel pipes
ond
rubber hoses. All connections must be tightened
with clips of
the strip
type (see
Fig. 11.411) or
the wire type (bleed
hose). Toke
core not to
overtighten the clips of the lotter type os there
is o risk of domoging the rubber.
The hose from the pipe
of the thermostot
body on the engine is routed to the heoter
through the f loor tunnel, the return bronch
possing ogoin through the tunnel to the pipe
of
the pump.
Arronge the hoses olong the sides
of
the floor tunnel so
thot they do not touch other
ports in the tunnel.
For detoiled informotion obout the routing of
the hoses refer to
Chopter 12.7.
11.9 otl COOLER
The oil cooler is stondord
equipment of
Skodo
120 LS models. lts construction resembles thot
of the rodiotor. lt is
instolled in the
engine
comportment (boy)
ond ottoched to the right-
-hond engine guord.
Speciol pressure
hoses
connect it with the engine. lts connecting
diogrom is shown in
Fig. 11.911.
As regords oil coolers for subtropicol ond
tropicol regions, refer to
Chopters 16.1
ond '16.2.

Diogrom

Outlet from engine-right-hond cooler socket,
2 -
Oil cooler, 3 -
Inlet into engine -
left-hond
cooler socket Removol ond
Refitting
Disconnect the hoses fronr the engine ond,
occording to circumstonces ond the purpose
of
the removol, detoch the oil cooler from
the
engine guord
or remove the engine guord
together with the cooler ond brocket. Empty the
oil contoined in the hoses ond the oil cooler
into o suitoble vessel. When refitting the oil
cooler into the cor,
proceed in occordonce with the circumstonces
of the removol. Secure the bolts conecting the
oil cooler with the engine guord
ond the brocket
(the brocket being locoted between the cooler
ond the guord)
with spring
woshers. Bolt down
the guord
over ploin
woshers ond use o spring
wosher for the bolted connection of the brocket
with the bodywork.
Use seoling
woshers when connecting hoses
to the engine ond the oil cooler, ond put
o seoling wosher olso under the bolt. Close the
bolt of the engine port
ot the flonge with the
pressure switch. Fosten the hoses so thot they
ore not stressed in their bends. The
hose from
the timing geor
cover should be routed horizon-
tolly ond the hose ot
the engine inlet so thot
it includes o downword ongle of obout 15 de-
grees with the horizontol plone. Top up
oil in
the engine.
11.10 COOLING SYSTEM DEFECTS,
TESTING, REPAIRS, AND
CLEANING
Defects ond Testing o) lf there is o marked loss of coolont, check
oll connections for leokoge. The
loss of coolont
con olso be coused by o leokoge of the rodiotor
(or heoter). lf the leokoge point
is not visible,
pressure-test the system without removing it
from the cor. Admit seoled-off oir ot o pressure
of 0.12 MPo
(1.2 kglcmz) into the filler neck ond look for
ploces where the coolont is seeping or dripping
out. Inspect not only the rodiotor but olso the
lreoter. An excessive loss of the coolont con be olso
coused by engine overheoting. In thot cose,
look for the couse of engine overheoting.
b) Points to check if the engine
is overheoting
- coolont level
- operotion of thermostots ond rodiotor fon
- condition of rodiotor (whether
clogged out-
side with dirt, or whether cooted inside with
scole)
c) Points to check if the engine does not worm
up properly:
- operotion of thermostots
