how to fix Honda CR-V Fifth Generation (2017-2022) engine knocking noise

Solution

1. Preparation

• Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, engine oil, oil filter.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical issues.

2. Check Engine Oil

• Sub-steps:
  1. Remove the oil dipstick and wipe it clean. Reinsert and remove it to check the oil level.
  2. If the oil is low, add the recommended engine oil (5W-20 for Honda CR-V).
  3. If the oil is dirty or has debris, proceed to change the oil and filter.

3. Change Engine Oil and Filter

• Sub-steps:
  1. Place an oil catch pan under the engine and remove the oil drain plug using a socket.
  2. Allow the old oil to drain completely, then replace the drain plug and torque it to manufacturer specifications (typically around 29 ft-lbs).
  3. Remove the old oil filter using an oil filter wrench. Apply a thin layer of new oil on the rubber seal of the new filter and install it.
  4. Fill the engine with new oil through the oil filler cap.

4. Inspect and Replace Components

• Sub-steps:
  1. Inspect engine mounts for cracks or wear; replace if damaged.
  2. Check the timing chain/belt for wear; replace if necessary.
  3. Tighten any loose components in the engine bay that may be causing noise.

5. Reassemble and Test

• Reconnect the negative battery terminal.
• Start the engine and listen for any remaining knocking noises.
