MECHANICAL SEAL INSPECTION

Remove the under cowl (page 2-11) (CBR650F/FA
only).
Check the bleed hole [1] of the water pump for signs of
coolant leakage.
• A small amount of coolant weeping from the bleed
hole is normal.
• Make sure that there are no continuous coolant
leakage [2] from the bleed hole while operating the
engine.
Replace the water pump body if necessary.

specified level after installation (page 3-9).
Drain the coolant (page 8-4).
