How to Replace an Oil Pump in a Dodge Ram

by Contributor

Losing lubrication in an engine will destroy it. The oil pump makes sure this doesn't happen by cycling oil through the engine and keeping it lubricated. In most cases, the oil pump lasts the lifetime of a car, but if there is an accident or if an engine needs overhauling, the oil pump in the Dodge Ram sometimes needs to be replaced.

Remove the Old Oil Pump

Step 1

Drain the cooling system of your Dodge Ram into a pan the disconnect the negative battery cables. Remove the accessory drive belt and the cooling fan and shroud.

Step 2

Take out the radiator and the oil fill tube with its adapter. Carefully remove the crankshaft pulley and the front cover.

Remove the oil pump then clean the surfaces with a rag to rid them of all debris and contaminants.

Install the New Oil Pump

Step 1

Install the new oil pump, tightening the first bolts to 44 in-lb and the second bolts to 18 ft-lb.

Step 2

Put the front cover back on and reinstall the crankshaft pulley. Add the oil fill tube and adapter then the radiator.

Step 3

Reinstall the cooling fan and shroud and the accessory drive belt. Reconnect the negative battery cables.

Turn the Dodge Ram on and check for leaks around all the parts replaced. Drive your car off the lifts if there are no leaks.
