In a very rare case if the noise is still heard,
the HLA is stuck in compressed position and
has to be replaced.
NOTE
There is no danger of damage to other
components if engine is run for few minutes
on no load condition.
e) Piston Cooling Nozzle :
Piston cooling nozzle is fitted on the block such
that the oil sprayed from it hits the underside of
the piston crown. This is very essential to cool the
piston crown temperature.
Refer Cylinder Block dismantling and Assembly in
this section for removal and fitment instructions.
f) Oil Pressure Switch :
An Oil pressure switch is used as a safety device
to indicate loss in oil pressure.
In a vehicle when the ignition is switched ON the
oil pressure warning light is illuminated because
the engine is not running and hence no oil
pressure is generated.
When the engine is running, pressure is built up in
the engine and the oil pressure warning light goes
off.
If the oil pressure is not as per the specified value,
the oil pressure light in the Instrument Cluster
glows. The most common reason for low oil
pressure is loss of oil.
