Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, impact wrench, multimeter.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Inspect and Replace Engine Oil

Remove the engine oil dipstick and check the oil level; top off if necessary.
If the oil is dirty or low, drain the old oil using a wrench to remove the oil pan bolt.
Replace with manufacturer-recommended oil and a new oil filter. Ensure to torque the oil pan bolt to manufacturer's specifications.

3. Check Engine Mounts

Raise the vehicle using a jack and secure it with jack stands.
Inspect engine mounts for cracks or separation. If found, remove the bolts securing the mounts using a socket set.
Replace with new engine mounts and torque bolts to specified values.

4. Inspect Exhaust System

Visually inspect the exhaust system for loose clamps, missing bolts, or damaged components.
Tighten any loose connections. If parts are damaged, replace them as necessary.

5. Inspect Drive Belts and Pulleys

Check the condition of the drive belts for wear and tension.
If worn, remove the belt by loosening the tensioner and replace it with a new one. Ensure proper tension is applied to the new belt.
