Instructions:
1. Prepare the Vehicle:
- Park your vehicle on a level surface and engage the parking brake.
- Let the engine cool down completely if it's been running.
- Disconnect the negative terminal of the battery.
2. Drain the Oil:
- Place the oil drain pan beneath the oil drain plug located under the oil pan.
- Use the appropriate wrench or socket to loosen the drain plug and let the oil drain completely into the pan.
3. Remove the Oil Filter:
- Locate the oil filter near the top of the engine.
- Use an oil filter wrench to loosen and remove the oil filter.
- Clean the filter mounting area and discard the old filter.
4. Remove the Oil Pump:
- Identify the oil pump, usually located near the front of the engine.
- Disconnect any hoses or electrical connectors attached to the pump.
- Use a socket set to remove the bolts holding the oil pump in place.
- Be careful not to drop any bolts into the engine compartment.
5. Replace the Oil Pump Gasket:
- Remove the old oil pump gasket from the mounting surface.
- Clean the mating surface thoroughly to ensure a proper seal.
- Apply a thin layer of sealant (if specified) to the new gasket.
6. Install the New Oil Pump:
- Place the new oil pump gasket onto the mounting surface.
- Carefully position the new oil pump and secure it using the bolts you removed earlier.
- Tighten the bolts evenly in a star pattern to ensure proper sealing.
7. Reconnect Hoses and Connectors:
- Reconnect any hoses or electrical connectors you disconnected earlier.
8. Add New Oil:
- Remove the oil filler cap and add new oil to the engine.
- Use a funnel to avoid spills and refer to your owner's manual for the recommended oil quantity.
9. Replace the Oil Filter:
- Install the new oil filter and hand-tighten it until snug.
- Do not overtighten the oil filter.
10. Test the Oil Pump:
- Reconnect the negative battery terminal.
- Start the engine and let it run for a few minutes.
- Check for any leaks around the oil pump and oil filter.
10. Complete Fluid Check:
- Verify the oil level on the dipstick to ensure it's between the "Full" and "Add" marks.
Once the oil pump replacement is complete and you've ensured there are no leaks, you can take your vehicle for a test drive to check its proper operation.
