Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery cable to ensure safety.
Allow the engine to cool down if it has been running.

2. Change Engine Oil and Filter

Raise the vehicle: Use jack stands to secure the vehicle at a comfortable height.
Remove the oil drain plug: Place an oil catch pan under the oil pan and remove the drain plug. Allow the oil to drain completely.
Remove the old oil filter: Use an oil filter wrench to unscrew the old oil filter. Make sure the rubber O-ring comes off with it.
Install new oil filter: Apply a small amount of new oil to the rubber gasket of the new filter. Screw it on by hand until snug, then tighten an additional 3/4 turn.
Reinstall the drain plug: Replace the oil drain plug and tighten to manufacturer specifications (typically around 25 ft-lbs).
Add new engine oil: Fill the engine with the recommended type and amount of oil (typically 5W-20 for this model) using a funnel. Check the owner's manual for exact specifications.

3. Inspect and Replace Oil Pump (if necessary)

Remove the oil pan: Drain any remaining oil, then unbolt the oil pan from the engine and remove it. Clean the mating surfaces on the engine block.
Remove the oil pump: Unbolt the oil pump from the engine block and disconnect any oil pickup tube attached to it.
Inspect the oil pump: Check for wear or damage. Replace the pump if it is damaged.
Install the new oil pump: Position the new pump and secure it with bolts to the manufacturer's torque specifications.
Reinstall the oil pan: Use a new gasket or sealant as necessary. Bolt the pan back in place.
