Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, multimeter, engine oil.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before opening any components.

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 drain old oil.
3. Replace the oil filter using an oil filter wrench.
4. Clean the drain plug and reinstall it with the specified torque setting (usually around 20-30 ft-lbs).
5. Refill the engine with the correct grade of engine oil as specified in the owner’s manual.

3. Inspect and Replace Components

Sub-steps:
1. Inspect all belts for wear and replace any that are frayed or cracked.
2. Check engine mounts for signs of damage or excessive wear and replace if necessary.
3. Tighten any loose bolts or connections in the engine bay, focusing on exhaust components and brackets.

4. Compression Testing (if needed)

Sub-steps:
1. Remove spark plugs using a socket set.
2. Insert the compression tester into the first cylinder and crank the engine for several seconds.
3. Record the compression reading and repeat for each cylinder.
4. Compare values to manufacturer specifications; address any cylinders with significantly lower readings.
