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. Main drive pulley is assembled on a roller bearing mounted shaft. Grease nipple is provided on front cover to grease the bearings. Grease the bearings every 250 hrs. of operation.
NOTE: Grease Specification: Mahindra’s Pro RED (or equivalent grease only to be used for greasing). Excessive greasing not recommended for bearings.
Draining the System Two drain plugs must be opened. One is on L.H. side of crankcase and one on radiator bottom tank. To speed up draining, remove the radiator cap. Ensure that the drains are not clogged. Close the taps after draining is complete. Cleaning out Dirt and Sludge Drain cooling system as directed above. Fill the cooling system with a solution of 1.0 Kg. of ordinary baking soda to 8.0 litres (2.11 US Gallons) of water. Do not replace the radiator cap. Operate the engine until the coolant is hot. Drain, flush with clean water and refill with a rust inhibitor or anti-freeze solution.
