How to Replace an Oil Pump on a Jeep CJ7

The Jeep CJ is a series of commercial vehicles that resemble the Willys military Jeep from World War II. American Motors Corporation manufactured the Jeep CJ7 from 1976 to 1986. These vehicles have several different engines, with a four-cylinder 2.5-liter engine being one of the most common. The oil pump for a Jeep CJ7 is under the engine, so you must access it from below the vehicle.

Instructions

Remove the cable from the batterys negative terminal with a socket wrench to prevent anyone from starting the engine. Raise the vehicle with a jack and support it on jack stands.

Place a drain pan under the oil drain on the crankcase. Remove the drain plug with a socket wrench, and allow the oil to drain into the drain pan. Replace the drain plug and store the oil.
