Mitsubishi ME993473 is the aluminium bodied water pump with four bolt pulley hub and steel impeller. It is used on Mitsubishi 4M40 engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
The same part is also sold as Mitsubishi ME200411 and Mitsubishi ME996789.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

All of these numbers are the same part.
Coolant leak from the weep hole
Coolant dripping from the pump body means the seal has failed. Replace the pump before the engine runs low and overheats.
Overheating
A worn impeller moves less coolant. If the engine runs hot with a good thermostat and radiator, check the pump.
Bearing noise or play
A rumble or play at the pulley means the bearing is worn and the seal will follow.
Service at the same time
Change the thermostat, belts and coolant while the pump is off.
