Solution

1. Preparation

Tools Required: Engine oil, oil filter, socket set, oil pressure gauge.
Check the owner's manual for specific oil type and capacity.

2. Change Engine Oil and Filter

Warm Up Engine: Run the engine for a few minutes to warm the oil, making it easier to drain.
Lift Vehicle: Safely raise the vehicle using jack stands.
Drain Old Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug and allow the oil to drain completely.
- Replace the drain plug and tighten to specified torque (typically 20-30 lb-ft).
Remove Old Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new filter with a bit of fresh oil.
- Install the new oil filter, tightening it by hand until snug.
Add New Engine Oil:
- Remove the oil fill cap and pour in the recommended amount of new oil.
- Replace the oil fill cap.

3. Test Oil Pressure

Connect Oil Pressure Gauge:
- Remove the oil pressure sending unit and install the oil pressure gauge.
Start Engine:
- Start the engine and observe the gauge reading. It should be within the manufacturer’s specifications (typically 25-65 PSI at idle).
Turn Off Engine:
- Shut off the engine and remove the gauge, reinstall the oil pressure sending unit.
