why does my Genesis G70 have excessive engine noise at startup?

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, mechanic’s stethoscope, oil catch pan, engine oil, new oil filter.
• Allow the engine to cool before starting the repair process.
• Disconnect the battery to ensure safety while working.

2. Change Engine Oil and Filter

1. Drain Engine Oil

   • Position an oil catch pan under the oil pan.
   • Remove the oil drain plug using a socket set and allow the oil to completely drain.
   • Reinstall the drain plug and torque it to the manufacturer's specifications.

2. Replace Oil Filter

   • Locate the oil filter and use an oil filter wrench to remove it.
   • Apply a small amount of new oil to the rubber gasket of the new filter.
   • Install the new filter, tightening it according to manufacturer specifications.

3. Add New Engine Oil

   • Add the appropriate type and amount of engine oil as specified in the owner’s manual.
   • Start the engine and let it run for a few minutes, checking for leaks around the oil filter and drain plug.

3. Inspect Timing Chain/Belt

1. Remove Engine Covers
   • Use a socket set to remove any engine covers blocking access to the timing chain/belt.
2. Inspect Tensioners and Guides
   • Check the tensioner for wear or failure; replace if worn.
   • Inspect the guides and the condition of the chain/belt for any signs of damage.
