Cooling System

Water Pump

The water pump is equipped with a sealed bearing. Adjusting or greasing will not be necessary.

Hose Connections

Check periodically to ensure all the connections are in good order and the clips are tight. A leaking connection results in loss of coolant and thus engine efficiency.

When using antifreeze in the cooling system, it is absolutely essential to have efficient connection so check these and should there be any doubt as to their serviceability, renew.

Fan & Fan Belts

A plastic fan is mounted on water pump and is driven vide fan belt by the main drive pulley. While the engine is in operation, the fan sucks air through the radiator core.

Slippage of belt on pulley can cause over heating. The Fan belts shall always be dry and free from oil or Grease. Incorrect belt tension results in its rapid wear.
