How to Install KA24E Oil Pumps
The KA24E is a four-cylinder 2.4-liter engine that Nissa made from 1988 to 1996. It appears in a variety of Nissan vehicles from this period, such as the Stanza from 1990 to 1992. An oil pump circulates oil through the engine to keep the moving parts lubricated while the engine is running. The oil pump in a KA24E engine consists of an inner and outer gear, which require replacement at the same time.

Disconnect the negative battery cable with a socket wrench to prevent the engine from starting. Remove the front engine cover with the oil strainer tube still attached. Discard the gasket for the front engine cover.
2Remove the retaining screw and mounting bolts from the cover of the oil pump with a socket wrench. Detach the cover for the oil pump from the front engine cover. Remove the inner and outer gears for the oil pump from the gear cavity.
3Clean the mating surfaces of the oil pump cover and the gear cavity with a shop rag. Place the new outer gear for the oil pump into the gear cavity. Place the new inner gear into the gear cavity with the grooved side facing up. Ensure the two gears mesh together properly and pack petroleum jelly into the gear cavity.
4Replace the cover for the oil pump and tighten the retainer screws to between 22 and 36 foot-pounds with a torque wrench. Tighten the mounting bolts for the oil pump cover to between 12 and 15 foot-pounds.
5Install a new gasket for the front engine cover, and replace the engine cover with a socket wrench. Attach the cable for the negative battery terminal and start the engine. Correct any oil leaks.
