my Genesis G70 makes a knocking noise when I accelerate what's wrong

Solution

1. Preparation

• Gather tools: socket set, torque wrench, OBD-II scanner, and engine oil.
• Disconnect the battery to ensure safety while working on electrical components.

2. Engine Oil Inspection

• Remove the oil dipstick and check the oil level.
• If low, add the recommended type of engine oil (refer to the owner's manual).
• Check the oil condition; if it's dirty or contains metal shavings, perform an oil change.

3. Engine Mount Replacement (if necessary)

• Lift the vehicle securely using jack stands.
• Remove the bolts securing the engine mounts to the engine block and chassis.
• Replace the damaged mounts with new OEM parts, ensuring they are torqued to manufacturer specifications (usually around 40-60 lb-ft, check manual).
• Reinstall all removed components.

4. Exhaust System Check

• Inspect the exhaust hangers for wear; replace if necessary.
• Tighten any loose bolts on the exhaust system, particularly at the manifold and catalytic converter.

5. Drive Belt Inspection

• Check the condition of the drive belts for fraying or cracking.
• Realign or replace the belts if they are damaged.

6. Ignition Timing Adjustment

• Connect the timing light to the battery and the #1 spark plug wire.
• Start the engine and observe the timing mark; adjust the distributor or ECU settings as necessary to achieve proper timing as specified in the service manual.
