Isuzu 1-87310835-0 is the engine water pump with its stacked V belt and multi rib pulleys on a sealed bearing, the aluminium body with the round outlet spigot, and the open impeller face with its gasket groove. It is used on Isuzu 6HK1 engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.

Yes, it is a direct replacement for the Isuzu 1-87310835-0 with the same fitting.
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.
Most failures come from contamination, cavitation from a restricted inlet, or running low on fluid. Check the inlet and the fluid before fitting the new water pump.
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 Isuzu 1-87310835-0. It is not made by the original manufacturer; the number only shows what it replaces.
