What it does
The oil pump pushes oil to the bearings, cam and valvetrain, building the pressure the engine needs to survive. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Prime the new pump with oil before installation so it picks up quickly on first start.
- Oil pan gasket: The pan usually comes off for this job.
- Oil and filter: Start fresh after the job.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
