How to Replace the Oil Pump on a 1989 Ford Econoline Van

An automobile engine will run only if it is properly lubricated, and the oil pump is responsible for this task. It pulls oil from the oil pan and distributes it throughout the engine. If you have a 1989 Ford Econoline van with an oil pump that needs to be replaced, even a novice mechanic can get the job done in less than an hour, using a few basic automotive tools.

Tools Used: Floor jack, 2 jack stands, Oil drain container, Ratchet and socket set, Torque wrench, Gasket scraper, Shop rags, Oil pump gasket, Oil pump, Oil pan gasket

Replace the Oil Pump

Park the van in a flat, well-lighted area. Turn off the motor and set the parking brake.

Raise the front end of the van with a floor jack. Place jack stands under the van and lower the vehicle down onto them with the floor jack. Roll the floor jack out from underneath the van.

Position a container to catch the oil underneath the oil pan drain plug. The oil pan is located under the engine at the front of the vehicle. It has a smooth metal cover. The drain plug is at the back of the pan. Use a ratchet and socket to remove the drain plug and allow the oil to drain into the container. Remove the container from beneath the van.

Remove the retaining bolts of the oil pan with a ratchet and socket. If the van has a diesel engine, lower the pan down onto the cross member. If it has a gasoline motor, remove the pan and set it aside.

Remove the oil pump mounting bolts with a ratchet and socket. You will see the pump and the strainer screen protruding down at the back of the engine (the area where the oil pan was the deepest). Pull the pump down and out of the engine. On gas engines, a pump drive shaft will come out with it. On diesel engines, lower the pump and tube retainers into the oil pan. Slide the oil pan and pump off of the cross member and onto the ground, and dispose of the old pump.

Remove all old gasket material from the oil pump mounting surface and from the oil pan sealing surface. Use a gasket scraper and shop rags to make sure they are clean.

Pour engine oil into the inlet port of the oil pump. Hand-turn the pump to allow the oil to be drawn in. This will prime the pump.

Install the new oil pump. On gasoline engines, push the drive shaft and oil pump up into the engine. Be sure to use a new gasket. Reinstall the oil pump mounting bolts and tighten them to 22 to 32 foot-pounds with a torque wrench. On diesel engines, put the pump into the oil pan first and then put the oil pan back on top of the cross member. At this point you can install the oil pump and new gasket. Tighten the mounting bolts to 22 to 32 foot-pounds.

Reinstall the oil pan and new gasket. Tighten the oil pan bolts with a ratchet and socket.

Raise the van with the floor jack until the van no longer rests on the jack stands. Remove the jack stands and use the jack to lower the van to the ground. Open the hood and use a funnel to pour new oil into the oil-fill port on top of the engine. The port is labeled with an oil can symbol. Check your owner's manual for the correct amount and type of oil to use.

Start the engine and make sure the oil pressure light goes off and stays off. Check for leaks beneath the vehicle. If you see any, the oil pan bolts may need further tightening.

Tips & Warnings

Dispose of old oil by taking it to a recycling center. Many automotive repair shops and auto parts stores also will dispose of your oil, usually at no charge.
