Solution

1. Preparation

Gather tools and materials.
Ensure the engine is cool before beginning work.
Disconnect the battery to prevent electrical issues.

2. Replace Oil Filter and Oil

Tools Required: Oil filter wrench, socket set, drain pan.
Sub-steps:
1. Drain the engine oil by removing the oil drain plug with a socket wrench and allow the oil to fully drain into the pan.
2. Remove the old oil filter using an oil filter wrench. Apply a thin layer of new oil to the rubber gasket of the new filter before installing.
3. Install the new oil filter and tighten it to the manufacturer's specifications.
4. Replace the oil drain plug and torque it to the specified value (typically around 25-30 ft-lbs).
5. Refill the engine with the appropriate type and amount of oil (5W-20 for most 2.5L engines).

3. Repair Oil Leaks

Tools Required: Wrench set, gasket scraper, RTV silicone sealant.
Sub-steps:
1. If oil leaks are found at the valve cover gasket, remove the valve cover by loosening the securing bolts.
2. Clean the mating surfaces with a gasket scraper to remove old gasket material.
3. Apply a new gasket or RTV silicone sealant according to the instructions and reattach the valve cover.
4. Tighten the bolts to the specified torque (usually around 7-10 ft-lbs).
5. If leaks are found at the oil pan, repeat the same cleaning and sealing process after removing the pan.

4. Verify Component Integrity

Tools Required: Torque wrench, inspection mirror.
Sub-steps:
1. Inspect all hoses and seals around the engine for cracks or wear.
2. Replace any damaged hoses or components as necessary.
3. Ensure all connections are secured and there are no obstructions.
