Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Change Engine Oil and Filter

Drain Old Oil
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug (use a socket wrench).
- Allow the oil to fully drain.
- Reinstall the drain plug and torque it to the manufacturer's specification (typically 25-30 Nm).
Replace Oil Filter
- Locate the oil filter (usually on the side of the engine).
- Use an oil filter wrench to remove the old oil filter.
- Prepare the new oil filter by applying a thin layer of new oil to the rubber gasket.
- Install the new oil filter and hand-tighten (do not over-tighten).
Add New Engine Oil
- Remove the engine oil filler cap.
- Pour the recommended type and amount of oil into the engine (check owner’s manual for specifications).
- Replace the oil filler cap securely.

3. Test and Inspect Oil Pressure

Install Mechanical Oil Pressure Gauge
- Locate the oil pressure sending unit and remove it.
- Install the mechanical oil pressure gauge in place of the sending unit.
- Start the engine and observe the oil pressure reading on the gauge. It should be within the manufacturer's specified range (typically 1.5 - 3.5 bar at idle).
Inspect Oil Pump (if pressure is low)
- If pressure is low, the oil pump may need to be inspected or replaced.
- Remove the oil pump (refer to the service manual for specific steps).
- Inspect for wear, damage, or blockages.
