Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Disconnect the battery to prevent any electrical short circuits during work.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.

2. Engine Oil Change

Tools Required: Oil filter wrench, socket set, oil catch pan, funnel.
Drain the engine oil:
1. Remove the oil drain plug and allow oil to fully drain into the catch pan.
2. Replace the drain plug and torque it to the manufacturer’s specifications (typically around 25 Nm).
Replace the oil filter:
1. Use the oil filter wrench to remove the old oil filter.
2. Lubricate the rubber gasket of the new filter with a small amount of oil and install it hand-tight.
Refill the engine with the recommended oil type (5W-30 or as specified in the owner's manual) using a funnel.

3. Inspect and Replace Engine Mounts (if necessary)

Tools Required: Socket set, torque wrench.
Remove the old engine mounts:
1. Support the engine with a jack or hoist.
2. Remove the bolts securing the mounts to the engine and chassis.
3. Replace with new mounts, ensuring proper alignment.
Torque bolts to manufacturer specifications (consult repair manual for exact values).

4. Timing Belt/Chain Inspection (if applicable)

Tools Required: Timing tool kit, socket set, torque wrench.
Inspect the timing belt/chain:
1. Remove the timing cover to access the belt/chain.
2. Check for signs of wear, fraying, or damage.
3. If worn, replace with a new timing belt/chain and tensioner.
Torque new components to the specified values.
