Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off and cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Oil Filter

Tools Required: Oil filter wrench, socket set, drain pan.
Remove the old oil filter using the oil filter wrench.
Ensure the rubber gasket from the old filter is removed from the engine mount.
Apply a small amount of new oil to the gasket of the new oil filter.
Install the new oil filter by hand, tightening it securely (do not over-tighten).

3. Change Engine Oil

Tools Required: Socket set, drain pan, funnel.
Place the drain pan under the oil pan and remove the drain plug with a socket wrench, allowing the old oil to drain completely.
Replace the drain plug and torque it to the manufacturer's specifications (typically around 20-25 ft-lbs).
Pour the new engine oil into the engine using a funnel, ensuring you are using the correct oil type and viscosity (refer to the owner's manual).

4. Test Oil Pressure

Tools Required: Oil pressure gauge.
Install the external oil pressure gauge into the oil pressure sending unit port.
Start the engine and observe the oil pressure reading on the gauge. It should be within the manufacturer's specified range (usually between 25-65 PSI at idle).
If pressure is low, replace the oil sending unit.

5. Reassemble and Final Checks

Reinstall any components removed during the process.
Reconnect the battery.
Start the vehicle and check for leaks around the oil filter and drain plug.
