Coolants

Presence of dirt in coolant chokes up passages in radiator,
cylinder head and crankcase, thereby causing overheating
of engine.
To prevent rust formation and freezing of coolant inside the
passages of radiator, crankcase and cylinder head use only
branded premixed coolant.
Coolant should be drained and fresh premixed coolant filled
every two years or 50,000 km., whichever is earlier.
