Yes, it was made for the Caterpillar C7, and 2 more listed under compatible equipment. Check the old water pump is marked 224-3253 or one of the cross references, because makers change parts between serial ranges.
On the Caterpillar C7, 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.
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 Caterpillar 224-3253. It is not made by the original manufacturer; the number only shows what it replaces.
