Cooling system :
If engine overheating occurs, there could be a fault in the cooling system
which may be on account of :
1. Less coolant in the system or dirt/ scale having accumulated inside
coolant passages, especially in the radiator core.
2. Chocking of radiator passages due to foreign material or damages.
3. Defective/stuck thermostat.
4. Loose fan drive belt.
5. Coolant leakage from system.
Always use genuine radiator cap of 1.0 kg/cm2 ( 14 psi ), if required to be
replaced. A proper radiator cap firmly fitted maintains pressure in the
cooling system.
Prevention of rust formation :
Use genuine co-branded premixed coolant in the cooling system to
prevent rust formation and freezing of coolant inside the crankcase
passages.
Fill the engine coolant auxiliary tank upto ‘FULL’ mark.
Changing of coolant in the cooling system :
(At every 50000 km or 2 years whichever is earlier)
a. Drain the cooling system and flush it with clean water.
b. Pour the genuine co-branded coolant into the radiator until it is full.
c. Start the engine. Top up the radiator with coolant.
d. Fill the auxiliary tank upto ‘FULL’ mark.
e. Ensure no leakage in the system.

rake system
The dual circuit service brake system operated through the tandem
master cylinder is designed such that one circuit will continue to provide
braking action if the other circuit fails. This vehicle is fitted with disc brakes
at front and drum brakes at rear.
Stopping the vehicle after loss of the brake fluid in one circuit will require
more pedal pressure and pedal travel than normal. Also stopping distance
will be longer.
Service brakes are vacuum assisted. In case of failure of vacuum, the
vehicle can still be stooped, however with a higher effort.
Bleeding the brake system
If the brake pedal becomes spongy, this may be due to air in the
hydraulic brake system.
Whenever any repair / overhaul or disconnecting of any brake pipe is
done, or level of brake fluid has fallen so low that air has been drawn
into master cylinder, it is necessary to bleed the system to remove the
trapped air.
Proceed as follows for bleeding the brake system :
a.
Clean all dirt from around the fluid container. Remove cap and top-
up fluid upto the maximum level.
b.
Remove dust cap at each bleed screw and clean the area around it.
c.
Attach the bleed tube to the front left calliper bleed screw and place
the other end in a clean jar containing sufficient fluid to submerge
the end of the tube.
d.
Pump the brake pedal 3-4 times slowly throughout its stroke and by
holding the pedal depressed, loosen the bleed screw and watch for
air bubbles in the glass jar.
