Yes, it was made for the Isuzu 3KB1, and 4 more listed under compatible equipment. Check the old water pump is marked 8-97069387-0 or one of the cross references, because makers change parts between serial ranges.
On the Isuzu 3KB1, 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.
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.
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.
No. It is an aftermarket water pump made to replace the Isuzu 8-97069387-0. It is not made by the original manufacturer; the number only shows what it replaces.
