Yes, it was made for the Mitsubishi 6D16, and 3 more listed under compatible equipment. Check the old water pump is marked ME996800 or one of the cross references, because makers change parts between serial ranges.
On the Mitsubishi 6D16, often 5,000 to 10,000 hours with clean fluid, much less with dirt or air in the system. It is usually changed on condition, not by hours.
Leaks from the seal or weep hole, noise or whining, overheating, or falling pressure or flow under load.
Clean them right back to metal and fit the new gasket or O-ring dry, unless the engine manual calls for sealant.
If the coolant is old or dirty, yes. Worn coolant is the usual cause of seal failure, and a new pump in old coolant fails the same way.
No. It is an aftermarket water pump made to replace the Mitsubishi ME996800. It is not made by the original manufacturer; the number only shows what it replaces.
