Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repair.

2. Check and Top Off Engine Oil

Tools Required: Oil container, funnel
If oil level is low, add the correct type and viscosity of engine oil as specified in the owner's manual.
Start the engine and let it run for a few minutes, then check the dipstick again to confirm proper oil level.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set, drain pan
Position the drain pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Lubricate the rubber O-ring of the new oil filter with a little fresh oil.
Install the new oil filter and tighten it according to the manufacturer’s torque specifications.

4. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper
Drain the engine oil completely into the drain pan.
Remove the oil pan by unscrewing the bolts and carefully prying it off.
Inspect the oil pump for damage; if faulty, remove it by unscrewing the mounting bolts.
Replace with a new oil pump, ensuring all gaskets are replaced and torqued to specifications.

5. Refill Engine Oil

Tools Required: Funnel
Reinstall the oil pan with a new gasket and torque to specifications.
Refill the engine with the recommended oil through the oil filler cap.
Start the engine and let it run, then check for leaks.
