Always use genuine auxiliary tank
cap. A proper cap firmly fitted
maintains pressure in the cooling
system and makes engine more
efficient by permitting a slightly
higher operating temperature.
Vacuum created in the system is
relieved by a valve provided in the
cap. Descale and clean cooling
system regularly.
Cleaning of cooling system.
This should be done at every
80,000 km or every two years
whichever is earlier.
While cleaning, the system is to be
totally drained out. Coolant from vent
pipes is to be drained out by
disconnecting these pipes from
auxiliary tank end side.
Fill the system with industrial soap
solution through filler cap in auxiliary
tank.
Wait for 2 to 3 minutes to allow air
to be vented and add solution to
bring the level to the top.
Do not install filler cap.
Operate engine for 5 mins. with the
flushing solution temperature above
80
0
C. at maximum engine speed.
Stop engine and drain soap solution.
Fill system with clean water. Be sure
to vent the engine for complete
filling.
Do not install filler cap.
Again operate the engine for 5 mins.
with water temperature above 80
0
C
at maximum engine speed.
Stop engine and drain water.
If water drained is still dirty, system
must be flushed again until water
drained out is clean.
Use a mixture of 50% water and 50%
ethylene glycol non-amino base
antifreeze to fill cooling system.
Fill the system slowly to prevent air
locks. During filling air must be
vented from the engine and radiator.
Wait for 2 to 3 minutes to allow the
air to be vented and then add
mixture to bring coolant level to the
top.
Install filler cap. Operate engine until
it reaches a temperature of 80
0 C, and
check for coolant leaks.
Wait until the coolant temperature
reaches below 50
0
C. Check coolant
level again to make sure the system
is full of coolant.
