Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Low oil pressure is serious. A worn pump, clogged pickup or worn bearings can all cause it. 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.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
