Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, mechanic's stethoscope, compression tester.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before starting any work.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place an oil catch pan under the oil pan and remove the drain plug to allow old oil to drain completely.
3. Replace the oil filter using an oil filter wrench.
4. Install a new drain plug with the correct torque specifications (typically 20-25 lb-ft).
5. Fill the engine with the manufacturer-recommended oil (usually 5W-30 or 0W-20) until the proper level is reached on the dipstick.

3. Inspect and Replace Timing Chain/Belt (if necessary)

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt (e.g., engine covers).
2. Align timing marks on the crankshaft and camshaft to the manufacturer specifications.
3. Remove the old timing chain/belt and inspect it for wear.
4. Install the new timing chain/belt, ensuring all timing marks align correctly.
5. Reassemble the components and check for proper installation.

4. Replace Engine Mounts (if necessary)

Sub-steps:
1. Support the engine with a jack and a block of wood to avoid damage.
2. Remove the bolts securing the damaged engine mount to the frame and engine.
3. Install the new engine mount, securing it with the appropriate torque specifications.
4. Lower the engine and check if the mount is properly seated.
